Stump Jump Chisel Ploughs

Stump Jump Chisel Ploughs CanberraThe stump jump chisel plough is an ideal tool for primary cultivation. The spring action of the tines and chisel points have been proven to penetrate where many other machines find conditions too hard. Other machines often have a closely bound spring, which means they become coil bound in hard ground and fail to penetrate. Our more open spring gives a longer, more progressive action, actually chiselling as the machine moves through the ground. This also reduces the horsepower requirement as each tine moving “averages” the load at any one point, whereas a rigid tine has no way of doing this. The machine is inexpensive and when used prior to rotary hoeing, power harrowing or discing there are many benefits. The subsequent operation is done faster, with less wear on the machine, less wear on the tractor and less diesel used. It is a question of the right machine for the job. In many cases a power harrow will manage primary cultivation – but it often does not do it easily as its design function is secondary cultivation. Use of a chisel plough prior more than offsets the cost of an additional operation as it means both machines are working to their optimum, saving time and money.

The five and seven tine machines have a 75 x 75 (3” x 3”) RHS perimeter fame with two centre supports which the top link frame is bolted to. The nine and eleven tine machines have two extra 75 x 75 RHS supports at each side. The frames all come fitted with wheel kit brackets. The lower link pin mounts are on the frame itself giving strength and a direct pull. Stepped pins (Cat 1 and 2) are fitted. The tine spacing is 300mm and adjustable. The tines themselves are extremely strong, Australian made silicone chrome spring steel. The machine has an excellent under frame clearance of 520mm. The standard points are 65mm wide reversible, 200mm and 400mm wide sweeps are also available.

Horsepower requirements vary widely but 8-10 HP per tine is a rough guide. Overall width of the machine is 9” wider than the cut width – ie 5 tine is 5’ 9”, 7 tine is 7’9” and so on. The wheel kit consists of a pair of 14” Holden wheels, height adjustable, fitted on the outside of the machine (increasing the overall width approx 450mm (18”)). Extra tines can be fitted if required to reduce tine spacing.

Comparisons against other brands: Most local brands are direct copies of the Berends whilst cheaper imported brands are usually designed for light, secondary cultivation conditions.

Rigid Tine Chisel Ploughs

Rigid Tine Chisel Ploughs CanberraThe rigid chisel plough is used in a similar fashion to the stump jump as a primary cultivator. The rigid tine is harder to pull as it has not got the ‘jack hammering’ effect of the stump jump tine. It should also be used in country which is known to be clean, as the tine is clamped onto the frame and will only shear the clamp bolts under load. The tines are extremely strong for this reason, using the same tines as the stump jump plough. The machine is ideal for lighter sandy soils where penetration and draft are not a problem, and also for customers where price is critical as it is cheaper than the stump jump. Tine spacing is 300mm and underframe clearance are similar to the stump jump, however the frame is 100 x 100 (4” x 4”) RHS.

Overall width of the machine is 9” wider than the cut width – ie 5 tine is 5’ 9”, 7 tine is 7’9” and so on. Horsepower requirements vary widely but 10 HP per tine is a rough guide. The wheel kit consists of a pair of 14” Holden wheels, height adjustable, fitted on the outside of the machine (increasing the overall width approx 450mm (18”)). Extra tines can be fitted if required to reduce tine spacing.

Comparisons against other brands: Most local brands are direct copies of the Berends whilst cheaper imported brands are usually designed for light, secondary cultivation conditions.

Coil Tine Chisel Ploughs

Coil Tine Chisel Ploughs CanberraThe coil tines are 30mm square, and are used for primary and secondary cultivation. They are ideal where deep penetration is required without bring subsoil up to the surface. They are commonly used in market garden operations to penetrate beneath the normal level of cultivation. The coil allows the tine to move, assisting penetration and reducing horsepower needed. Coil tines do not disturb the surface as much as the wider chisel plough tines. This is useful in operations as pasture renovation and plough or rotary hoe pan breaking. The finer tine is also good for secondary cultivation where a heavy machine is needed for heavy soils. The frame is 100 x 100 (4” x 4”) RHS, similar to the rigid chisel plough.

Horsepower requirements vary widely but 8-10 HP per tine is a rough guide.

Overall width of the machine is 9” wider than the cut width – ie 5 tine is 5’ 9”, 7 tine is 7’9” and so on. The wheel kit consists of a pair of 14” Holden wheels, height adjustable, fitted on the outside of the machine (increasing the overall width approx 450mm (18”)). Extra tines can be fitted if required to reduce tine spacing.

Comparisons against other brands: Most local brands are direct copies of the Berends whilst cheaper imported brands are usually designed for light, secondary cultivation conditions.

S Tine Cultivators

S Tine Cultivators CanberraS tines are one of the most versatile and valuable machines a farmer can own. By working with the weather, an S tine can be used from primary cultivation to creating a seed bed (like a power harrow). In fact the design brief of the original power harrows was to do the job of the S tine. The reason was that in Europe there is not much time between harvest and winter to re-sow paddocks, and with larger tractors being used and S tines being so easy to pull they were getting wider and wider models. These had to multi-fold to follow ground contours and travel down narrow European roads. The power harrow was designed to use the tractor horsepower via the pto to increase the cultivation action while reducing the overall width. They have some advantages over S tines and disadvantages. In many ways they are symptomatic of the problems associated with bringing European designed machines to Australian conditions. Larger European companies often put a lot of money into promoting machines, even when there are cheaper more appropriate machines on the market. In light pasture renovation and working up a clean paddock after a summer crop the S tine will work faster than a power harrow, using less diesel, less wear and tear on the tractor and less consumable cost. An S tine costs just 15% of a comparable size power harrow. For many farmers the S tine is a more suitable tool to their operation than a power harrow.

S tines are a wearing part. The cultivating action of the S tine involves it vibrating continuously, which can eventually lead to the tine breaking in hard conditions. If helper springs are fitted this will not occur for a long time, as the helper reduces the vibration and fatigue on the tine. Heavy Duty S tines act in the same way as the Standard S tines and helper springs are also available for these. Tine breakage is most commonly caused on newer machines by turning too sharp or going backwards.

Our S tines are manufactured in Italy by one of the leading tine manufacturers in the world, which are hot shot peened. This involves bombarding the tine during formation with tine steel balls which compresses the air pockets out of the tines. There are many inferior suppliers and we recommend you source your tines from us, as with “will fit” parts suppliers you get what you pay for – a cheaper part! Tines are not an expensive part, especially when the overall running cost of an S tine is compared to other cultivating machines such as power harrows.

The width of an S tine relates to its working width. The overall machine is 125mm wider than the listed width (ie 2.4m machine has overall width of 2.525m). If wheels are fitted these go on the outside adding another 500mm.

All S tines (Standard and Heavy Duty) are available with four point options:

  • Standard reversible point - suitable for general cultivation and pasture renovation.
  • Lucerne or pasture point – bi-metal point with the acting part being hard spring steel. Used, as the name implies, in lucerne but also commonly used to cut slots in pasture mat, which often gives a significant production increase at minimal cost.
  • 2 ½” Goosefoot – wider point is good at penetration and higher disturbance cultivation.
  • 4” Duckfoot – covers 100% of cultivation on the standard tine set-up. Used to quickly spill out weed growth in previously cultivated ground, or working up previously cultivated ground. Good at cutting off tap roots and mixing in fertiliser.

Crumbler rollers are optional and work especially well in cultivated ground. Clods on the surface can skip about when the machine is used without a crumbler roller, whereas the rollers breaks them down and pushes them in, allowing the tine to hit and break them up on a subsequent pass. In working down cultivated ground a roller may speed operations by 30% or more. The roller is also useful to help control depth of the machine, and even on opening up pasture, the roller can help level clumps and clods which may be thrown up.

Standard S Tine Cultivators 

 

Standard S Tine Cultivators 1The Standard S tine section is 32 x 10mm and is fitted to a 50 x 12 frame. We do not use the heavier frame on this size tine as it is too rigid and increases tine breakage (source: Kongskilde – originator of the S tine or Triple K) and we have no problems with the strength of the 50 x 12 frame, which is gusseted every 400mm. In fact, being less rigid, the whole machine vibrates more effectively, providing a better finish. All machines up to 2.4m are fitted with Cat 1 linkage frame with a single rear stay. All 2.8m to 3.6m machines are fitted with a Cat 2 linkage frame with three rear stays. Cat 1 and Cat 2 frames are interchangeable on request. The headstock can be offset if required for working under trees etc. The Standard model has four rows of tines providing extremely good trash clearance. Approximate horsepower requirements are as follows:

1.2m 18-25HP 1.6m 18-30HP 2.0m 20-40HP 2.4m 25-50HP
2.8m 35-60HP 3.2m 40-70HP 3.6m 45-80HP    

Standard S Tine Cultivators CanberraThe 5.4m folding wing S tine consists of a centre frame (approx 2.2m wide) and two outer frames (approx 1.6m wide each). The two outer frames fold up hydraulically to provide a transport width of 3.5m. There are four solid rubber wheels mounted on the unit to provide additional support for the frame. The crumblers are standard on this machine and overlap to provide the perfect finish.

Comparisons against other brands: Most local brands still mount the standards tines on a rigid 50 x 50 square frame. This is generally because they are unable to source the appropriate clamps to mount on the favoured 50 x 12 frame thus making their machine more rigid, less effective at vibrating and more prone to tine damage.

Heavy Duty S Tine Cultivators

The Heavy Duty S tine are designed to be more primary cultivation orientated than standard tines, being heavier and more rigid. The section of the HD S tine is 45 x 12mm and is fitted to a 50 x 50mm frame. They are ideal for working down hard ground and pasture renovation, especially when fitted with tine helpers. Tine helpers restrict the movement of the tine and reduce tine breakage greatly, especially in arduous conditions such as in rocky ground.

The 2.4m is fitted with a Cat 1 headstock and a single rear stay. The 3.0m and 3.6m are fitted with Cat 2 headstocks and three rear stays.

Approximate horsepower requirements are as follows:

2.4m 35HP+ 3.2m 45HP+ 3.6m 55HP+

Comparisons against other brands: There is not much competition in the Heavy Duty S tines.

Deep Tillage Ploughs

Deep Tillage Ploughs CanberraThe deep tillage plough is primarily used for breaking up the hard pan so as to increase water absorption, reducing water run off, aerating the soils and generally improving the soil profile. This is turn will lead to better microbial activity, nutrient breakdown and release and therefore increased pasture growth. Unlike other cultivation machinery such as rippers or disc ploughs, the soil layers are not mixed up and there is minimal disturbance to the surface. The main frame is made from 100 x 100 x 9mm material. The 24” high tensile cast shanks are Australian made and have an underframe clearance of 610mm and are protected by 1” shear-pins. The points and shin guards are replaceable and available with tungsten tips. Each tine has a breakout force of 4000ft.lbs. Tine spacing is set at approximately 12” (300mm) with a horsepower requirement of 15HP per tine. This will vary depending on the soil conditions. When working in cropping ground, a large diameter crumbler can be fitted to break down any clods, reducing crusting on the surface and provide a level penetration. The crumbler can be fitted with two adjustable ratchets or optional phasing cylinders (much more expensive).

Deep Tillage Ploughs CanberraThe 2 tine unit is mounted on a single headstock type frame only whilst the 3 tine unit consists of a single row toolbar approximately 1.8m wide with diagonal end supports. The 5, 7, 9 and 11 tine models are all mounted on a double row frame.

The overall widths (approx) are as follows:

 5 tine – 6’

 7 tine – 8’

 9 tine – 10’

 11 tine – 13’

The machine is standard with a pair of Holden wheels to help control working depth. The wheel kit is fitted on the outside of the machine (increasing the overall width approx 450mm (18”)). Extra tines can be fitted if required to reduce tine spacing.

Comparisons against other brands: There are a couple of Australian manufacturers but rarely any imported machines. The local companies tend to focus on the more elaborate machines to suit broad-acre applications. Nearly all are overpriced considering the tines and frames are of similar construction.

Ground Breakers

Ground breakers CanberraThe ground breaker is primarily used for breaking up the hard pan so as to increase water absorption, reducing water run off, aerating the soils and generally improving the soil profile. This is turn will lead to better microbial activity, nutrient breakdown and release and therefore increased pasture growth. Unlike other cultivation machinery such as rippers or disc ploughs, the soil layers are not mixed up and there is minimal disturbance to the surface. The specially curved and twisted European tines are designed to loosen the soil more effectively than conventional straight shank tines by gently vibrating the hard pan from the bottom up. This produces more lateral fracturing between the tines without bringing the sub-soil to the surface or burying residue. Retaining surface residue will prevent top soil erosion and reduce moisture loss through evaporation. It is also less likely to create clods on the surface, leaving a smoother finish. For a clean finish, it is most effective when there is some moisture in the soil but not too wet. Compact soils prevent root development and reduce water absorption. By loosening the soil, roots are able to access groundwater during dry periods.

Can be used prior to, or in conjunction with, using power harrows/rotary hoes. The tines on power harrows tend to compress the soil at the same depth creating a thin pan-layer which impedes root growth. Running the Groundbreaker 100mm lower than the harrows will bust the pan without bringing up the subsoil. By loosening the soil prior to cultivation also enables the tractor to be run at a higher gear saving fuel and time with less wear on that implement.

Ideal in “No-Till” planting systems as the Groundbreaker allows the stubble to remain anchored and upright, unlike other tillage implements which loosen the stubble and subsequently create difficulties for no-till drills.

Ground breakers CanberraAll tine components are made from boron steel which provides great flexibility and long wear life. The Special Heat Treatment Process offers a surface hardness of HRc50. The components are then shot-peened and painted. The 15mm tine shank provides 900mm under-frame clearance and is capable of digging down to 18” depth depending on soil conditions. Reversible point is 40mm thick and angled for easy soil penetration. Case hardened points are available. The frame is made from 150 x 150 x 10mm RHS with 25mm end plates. The clamp brackets are made from 32mm plate and are fitted with 20mm high tensile shear bolts. Replaceable 8mm shin guard prevents wear to tine.

They come standard in 2, 4 and 6 tine models and require approximately 20-35HP per tine, depending on soil conditions.

Comparisons against other brands: This style of machine is common in Europe however there are few local manufacturers/importers. A lot of Australian tillage equipment is based around American agricultural practises.

Disc Ploughs

Disc ploughs (sometimes referred to as disc harrows) are still a popular cultivation tool with good reason. They break up soil for preparing crops or controlling weeds. Discs can cut up and mix in trash, are very hard wearing, long lasting and easy to use. They will chop up matted pasture where a chisel plough will have difficulty breaking down the matted turfs once they are floating around on the surface. A number of passes can create a fine tilth suitable enough for seeding. They can also be useful for incorporating organic matter or fertiliser back into the ground. Disc are often used to create fire breaks around properties. All Berends discs are fitted with very high quality discs manufactured by Bellota, one of the worlds leading disc manufacturers. All Bellota discs are manufactured under strict quality specifications that ensure the right hardness and uniformity throughout the disc.

Bellota offers a Life-time warranty for any manufacturing failure.

Berends Linkage Offset

Berends Linkage Offset CanberraThis medium duty offset disc is designed for small to medium size tractors. They are fitted with 28mm (1 1/8”) square high tensile gang bolt axles and high quality triple sealed bearings. The 10, 12, 14 and 16 plate machines have four bearings whilst the 18 plate has 6 bearings. The 10 and 12 plate models are supplied with a single boom main frame with a support bar between the gangs whilst the 14-18 plate are supplied with a double boom main frame. Adjustment is very simple, the U – bolts which clamp the gangs on are simply loosened and the gangs can be adjusted laterally and for angle. Berends Linkage Offset CanberraThe standard set-up for an offset discs is the front gang running at a 21° angle whilst the rear gang is set at 23°. There is an art to setting up a disc, but if you have lateral and full angle adjustment like our discs have you are able to set a disc to give a level 20 finish. 10 plate machines are fitted with 18” x 4mm scalloped discs, 12 plates with 20” x 4mm scalloped discs and the remainder are fitted with 22” x 5mm scalloped discs. Other sizes and types of discs are available on request. Each machine takes approximately 2.5-3HP per disc to pull, depending on conditions. Prong scrapers are also available for heavy clay soils.

Comparisons against other brands: There are not many Australian disc manufacturers full stop and the rare few don’t focus their attention on the small to medium size range of linkage discs. They are generally not geared up to do production run quantities so when they do small discs they find they are usually over-priced. In recent times there have been some ‘cheap’ imported disc ploughs coming out of China however they tend to be too light for Australian conditions. They are usually made for light soil that has been worked up many times. Not only is the structure light, but the bearings (if they have any) and axles will often not cope with the odd rock or stump. Our bearings and axles have been proven for many decades in Australia and are even used on our larger trailing RM40 machine (which weighs over 1200kg). Most use disc blades made in China, India or South America. Many are made to a price with little concern for steel quality or the correct manufacturing processes. We often see inferior discs which have split (laminated) or broken in half.

GM40 Linkage Offset

GM40 Linkage Offset CanberraThis Gibbins Rawlings machine is a heavier duty version of the Berends linkage model. It is ideal for all types of terrain however it is most commonly used in market gardens, orchards and for firebreaks, where the operator wants the strength and weight of a large disc but the versatility and compactness of a linkage model.

Using solid cast iron disc spools instead of pipe spacer spools almost doubles the weight of the machine. Each spool is individually machined and by providing the weight in the gangs rather than on the frame (or ballast) reduces the load onto the bearings. More weight also means a better penetration in hard ground. The spools also have a different diameter at the points where they touch the discs. This means that the disc doesn’t have a ‘pinch’ point where the spool on either side of it, touch in the same place. This reduces the stress on this part of the disc when it is under load (during cultivation) compared to machines which run a straight spool between the discs.

The main frame and headstock is also much heavier. The headstock is supported by two spring loaded pressure screws which help prevent damage in rocky or undulating conditions.

They are fitted with 28mm (1 1/8”) square high tensile gang bolt axles and high quality greaseable flanged bearings. The 18 plate machines have six bearings whilst the 20, 22 and 24 plate discs have eight bearings. Berends use shorter axles on the heavier disc ploughs, which means more bearing support. This may cost more to produce but it provides a stronger set-up in hard going. All come standard with 22” x 5mm scalloped discs with other sizes and types available on request. Adjustment is very simple, the U – bolts which clamp the gangs on are simply loosened and the gangs can be adjusted laterally and for angle. The standard set-up for an offset discs is the front gang running at a 21° angle whilst the rear gang is set at 23°. There is an art to setting up a disc, but if you have lateral and full angle adjustment like our discs have you are able to set a disc to give a level finish. Each machine takes approximately 2.5-3HP per disc to pull, depending on conditions. Prong scrapers are also available for heavy clay soils.

Comparisons against other brands: There are few companies in Australia who make such a strong, heavy duty linkage offset disc. Many claim to be equivalent but sit somewhere between this model and the medium duty model in regards to weight and performance. As mentioned above, many companies just don’t focus their attention on these types of discs, and usually price themselves out of the market as a result. Most use disc blades made in China, India or South America. Many are made to a price with little concern for steel quality or the correct manufacturing processes. We often see inferior discs which have split (laminated) or broken in half.

TH30 Linkage Tandem

TH30 Linkage Tandem CanberraThis Gibbins Rawlings machine is a similar model to the GM40 above except that the four gangs are set up in a tandem arrangement. The front two gangs throw out to either side, whilst the rear two gangs throw the soil inwards. This set-up means that the operator doesn’t need to worry as much about angle set-up as each gang counter-acts the opposing gang resulting in an even pull. (Offset models can be problematic for pulling to one side when incorrectly setup). It is ideal for all types of terrain however it is most commonly used in market gardens, orchards, vineyards and for firebreaks, where the operator wants the strength and weight of a large disc but the versatility and compactness of a linkage model. Refer to the GM40 for more machine details.

The front and rear gangs are independently adjusted through a pair of heavy duty ratchets (optional rams available). This allows the operator to easily change from an aggressive cut to a light tickling of the top soil. A 21 spring loaded chisel plough tine is fitted in the middle of the frame to rip the small section of ground left untouched by the front two gangs.

Each machine takes approximately 2.5-3HP per disc to pull, depending on conditions. Prong scrapers are also available for heavy clay soils.

Comparisons against other brands: There are few companies in Australia who make such a strong, heavy duty linkage disc at such an affordable price.

RM40 Trailing Offset

RM40 Trailing Offset CanberraThis Gibbins Rawlings machine is heavy duty trailing version of the GM40 linkage model. It is ideal for all types of terrain but particularly suited to cropping and pasture renovation. It suits operators who don’t have the horsepower, the acreage or the money to justify a larger, heavier trailing model.

Refer to the GM40 regarding spools, bearings, and axle set-up. The main frame is supported by two spring loaded pressure screws which help prevent damage in rocky or undulating conditions and help with weight transfer on the gangs. Prong scrapers are standard on this machine with formed scrapers on request. The trailing model is fitted with a hydraulically controlled wheel kit (consisting of two Holden wheels). This enables the machine to be transported between cultivation. A transport bar is also fitted which locks the wheels down and protects the ram from shocks during transport.

The drawbar is bolted on and is fully adjustable. This allows the machine to be offset to one side for orchard (under tree) cultivation.

An optional jack is also available for this drawbar. Each machine takes approximately 2.5-3HP per disc to pull, depending on conditions.

Comparisons against other brands: There are few companies in Australia who make smaller trailing offset disc ploughs, instead focusing on the larger more expensive models. Refer to our ‘comparisons’ sections in the GM40 section.

RM75 Trailing Offset

RM75 Trailing Offset CanberraThis Gibbins Rawlings machine is a heavier version of the RM40 trailing model. It is ideal for all types of terrain but particularly suited to cropping and pasture renovation. It has bigger 40mm (1 ½”) square high tensile gang bolt axles. Therefore the bearings are bigger to suit and the solid cast spools are also much larger. This all increases the weight of the machine dramatically, providing better penetration than the RM40, and less passes required to achieve a similar cultivation depth. The heavier axles and bearings allow it to be used in harder country. The 18 and 20 plate models are fitted with 6 greaseable flanged bearings whilst the 22, 24 and 28 plate models are all fitted with 8 bearings. Each spool is individually machined and by providing the weight in the gangs rather than on the frame (or ballast) reduces the load onto the bearings. More weight also means a better penetration in hard ground. The spools also have a different diameter at the points where they touch the discs. This means that the disc doesn’t have a ‘pinch’ point where the spool on either side of it, touch in the same place. This reduces the stress on this part of the disc when it is under load (during cultivation) compared to machines which run a straight spool between the discs.

  • The main frame is supported by two spring loaded pressure screws which help prevent damage in rocky or undulating conditions and help with weight transfer on the gangs.
  • Prong scrapers are standard on this machine with formed scrapers on request.
  • The wheel kit on the RM75 consists of two Landcruiser wheels controlled by a hydraulic ram. This enables the machine to be transported between cultivation. A transport bar is also fitted which locks the wheels down and protects the ram from shocks during transport.
  • The drawbar is bolted on and is fully adjustable.
  • All come standard with either 24” x 5mm or 24” x 6mm scalloped discs.
  • An optional jack is also available for this drawbar. Each machine takes approximately 3-4HP per disc to pull, depending on conditions.

Comparisons against other brands: It is relatively simple in design (not over-designed) yet really strong. This model has been tried and tested for over 40 years with only small changes during that time. You will struggle to find a similar spec disc plough at better price. We have used Bellota discs for almost 20 years without fault. Some main brand suppliers keep chopping and changing disc suppliers based purely on price rather than quality and many could not tell you honestly that they have never had issues with disc qualities at some stage in the last ten years. Berends believe when you are on to a good thing then you stick to it.

RM80 Trailing Offset

RM80 Trailing Offset CanberraThis Gibbins Rawlings machine is virtually the same as the RM75 disc plough with only a few changes.

Why does Berends bother making two models with only small differences between them? Gibbins Rawlings had been making both these models since the 1960’s and we still continue to get asked today specifically for either an RM75 or an RM80. The fact is that both machines are great discs and when a farmer wants the same model as he first owned and not another model, then who are we to argue.

The specifications are basically the same as the RM75 except for the following details: The axles are shorter on the RM80 which means additional support in rocky country. The 20 plate model is fitted with 8 greaseable flanged bearings, the 24 and 28 plate models are both fitted with 12 bearings and the 32 plate is fitted with 16 bearings.

The drawbar is fitted with a pressure screw bar connected to the wheelkit. When the wheels are lifted off the ground, there will be a transfer of weight from the tractor to the front gang. The higher the lift the more pressure is created and the greater the front disc penetration.

The wheel kit on the RM80 consists of two flotation wheels controlled by a hydraulic ram. The drawbar is bolted on and is fully adjustable as well as having height adjustment for mounting to higher tractor drawbars. It is standard with a parking jack.

  • All come standard with either 24” x 5mm, 24” x 6mm or 26” x 6mm scalloped discs.
  • Each machine takes approximately 3-4HP per disc to pull, depending on conditions.

Comparisons against other brands: Refer to the RM75.

TH100 Trailing Tandem

TH100 Trailing Tandem CanberraThis Gibbins Rawlings machine is a similar model to the RM80 above except that the four gangs are set up in a tandem arrangement. The front two gangs throw out to either side, whilst the rear two gangs throw the soil inwards. This set-up means that the operator doesn’t need to worry as much about angle setup as each gang counter-acts the opposing gang resulting in an even pull. (Offset models can be problematic for pulling to one side when incorrectly setup).

The front and rear gangs are independently adjusted through a pair of heavy duty ratchets (optional rams available). This allows the operator to easily change from an aggressive cut to a light tickling of the top soil. A spring loaded chisel plough tine is fitted in the middle of the frame to rip the small section of ground left untouched by the front two gangs. The two rear gangs are fitted with a smaller furrow filler disc which helps create a level finish by knocking off any ridges produced by the front gangs. The 28 plate model is fitted with 8 greaseable flanged bearings, the 32 plate model is fitted with 12 bearings and the 36, 40, 44 and 48 plate models are fitted with 16 bearings.

  • The drawbar is fully adjustable for mounting to different height tractors and fitted with a high parallel lift for better transportation.
  • The wheel kit on the TH100 consists of four Landcruiser (750 x16) wheels controlled by a hydraulic ram. It is fitted standard with a parking jack and formed scrapers which are individually curved to suit the disc.
  • All come standard with either 24” x 5mm, 24” x 6mm or 26” x 6mm scalloped discs.
  • Each machine takes approximately 3-4HP per disc to pull, depending on conditions.

Comparisons against other brands: Extremely well priced yet a robust machine proven over many decades.

FTH100 Trailing Tandem

This model was developed for farmers and contractors who required a tandem disc which could be made narrower for road transport and getting through gates. The front and rear gangs are hydraulically controlled through a unique greaseable turntable system (similar to our hydraulic grader blades). This system allows the discs to be hydraulically adjusted from a straight cut (for fine tillage) to be running parallel with the main frame. This is a 90° adjustment and means that the overall width of the discs in transport mode is less than 8’ (2.4m) wide regardless of which size model it is. The main frame is made up of two main beams of 200 x 100 x 9mm rhs, a centre beam of 125 x 125 x 9rhs and a number of cross beam supports.

The centre beam supports the two sliding clamps which are fitted with nylon inserts for long wear and minimum friction. These clamps are each connected to a 3”x 16” hydraulic ram. The gang axle and bearing set-up is identical to the TH100 model.

A chisel plough tine is fitted in the middle of the frame to rip the small section of ground left untouched by the front two gangs. The two rear gangs are fitted with a smaller furrow filler disc which helps create a level finish by knocking off any ridges produced by the front gangs.

  • The drawbar is fully adjustable for mounting to different height tractors and fitted with a high parallel lift for better transportation.
