RM 2000-85 Kubota RM 2000-85 Specifications & Technical Data (2016—2026)

Front furrow width adjustment

As standard equipment, front furrow width adjustment is via a turnbuckle. Hydraulic cylinders can be specified as an option.

Sequence valve

The sequence valve controls the reversing cycle of the plough. It automatically activates an alignment cylinder which "narrows" the plough prior to reversal. After reversal, the plough returns to its working position. This system gives a smoother reversal of the plough bodies.

Memory valve

The memory valve together with the memory-sequence valve, is also activated during reversal; it closes the plough down to the narrowest ploughing width of 12" (30 cm) before reversing. Once the cycle is completed, it returns automatically to the pre-set furrow width. The memory valve is fitted to the 4, 5, 6 furrow Variomat® ploughs of the RM2000/RM3000 series, depending on countries.

Two different systems

Kubota Variomat® is available in two variants – with hydraulic or mechanical adjustment of the furrow width. The hydraulic variant allows adjustments of the furrow width from the driver’s seat ‘on the move’. The practicality of being able to determine not only the depth, but also the width of the furrows is crucial if the best results are to be achieved. The pulling line adjusts automatically thanks to the auto-line.

The Variomat® RM2000 serie ploughs

The models RM2000V-RM2005V offer the same design as for the RM2000-RM2005 ploughs. The only difference is the Variomat®. This system offers easy working width adjustments "On the Move". Several possibilities are offered to easily change the working width: manual adjustment of the working width and of the front furrow with a turnbuckle hydraulic adjustment of the working width and manual adjustment of the front furrow with a turnbuckle hydraulic adjustment of the working width and automatic hydraulic adjustment of the front furrow.

Easy to operate

The furrow width adjustment not only increases the ploughing output but reduces the fuel consumption in relation to output. For RM2000-RM2005: simple step-wise ploughing width adjustments. Only 1 bolt to reposition. For the Variomat® models RM2000V-RM2005V, easy adjustments on the move from 30 to 50cm (12-20").

Easy adjustment

The front furrow can easily be adapted to different tractor brands and wheel width settings. This is done via a parallelogram, manually adjusted by a turnbuckle or optional with a hydraulic cylinder. A memory or a hydraulic alignment of the frame is available. The Kubota auto-line system always provides the correct pull line. All models are available with an interbody clearance of 85 cm or 100 cm. The RM2000 serie offers 3-5 furrow ploughs with the exception of RM2005-RM2005V, 100cm interbody clearance, which are available as 3-4 furrow ploughs. Most models are extendable by 1 body to the limits above mentioned.

Variomat® ploughs

The RM3000V-RM3005V are fitted with the Variomat® for easy furrow width adjustments. This system helps you save time, optimise the output to the field conditions and save fuel consumption per Ha. For instance, you can vary the working width from 30 to 50 cm (12-20") on the RM3005V with 85 cm interbody clearance. 20-40% extra performance can then be achieved with even lesser fuel consumption per Ha. An interbody clearance of 100 cm is also available.

Variations “on the move“

The Variomat® is simply operated via a turnbuckle or a hydraulic cylinder. The front furrow is adjusted separately in the same manner. With the hydraulic version, the working width can be adjusted on the move. For extra comfort while reversing, the RM3000V–RM3005V can be fitted with a sequence hydraulic automatically bringing the plough to the narrowest working width before turning.

Add-on system

Any 3, 4 and 5 furrow models can be extended by one body, max. 6 furrow plough. The RM3000 serie features a rear or a frame mounted wheel.

Furrow Splitter

Bolted to any parts of the mouldboard or share, the furrow splitter is designed to cut through heavy soils making it easier for following operations.

Extension and Weight Requirements

Most models can be extended by one body. All weights are given without optional equipment (net weights). The lift-requirements are given with the following equipment: depth wheel, one coulter and skimmers for all furrows. Weights and lifting requirements are given for ploughs with 85 cm "interbody clearance". For ploughs with 100 cm clearance, please adjust according to the following: Weight + 15 kg/body, lifting requirement + 50 kg/body. Most ploughs with stepless ploughing width and interbody clearance of 85 cm have a working width between 30-45 cm, while ploughs with 100 cm have a working width between 35-50 cm.

Smooth and safe turnover

The headstocks employ a strong 80 mm turnover cylinder, positioned at the rear of the headstock mast, to give correct and safe turnover. The design retains the proven Kubota concept of having the centre of gravity close to the tractor in order to minimise lift requirement and to improve stability.

Quicker than ever

With today’s demands for higher output, both tractor and plough are expected to perform quicker than ever before.

Low lift requirements & more stability

The first assembly mounted to the main support allows the plough to be as close as possible to the tractor. Therefore the lift requirements are significantly reduced compared to other brands. This smart design also contributes to a greater tractor and plough stability, particularly appreciated on hilly grounds.

Suits all tractor models

The smart design of the headstock 200 allows easy adaptations to suit any tractors irrespectively of wheel widths or linkage geometry constraints.

Easy adjustable skimmer

To ensure optimum positioning of the skimmer, a quick adjusting system is incorporated on all plough models. The skimmer is very easy to adjust and can be moved in all directions to suit field conditions. Special indentations on the skimmer arm provide correct location and depth setting. Since the fixing bracket and stalk are fixed to the plough’s leg assembly, the skimmer is easily adjusted up or down by loosening only one bolt. Once adjusted, the bolt is tightened and locked to ensure a correct and rigid assembly. The skimmer is available in two versions: standard manure and maize skimmer for those difficult conditions with large amounts of trash. Skimmers are recommended for efficient burial of stubble, grass, straw, and weeds to provide a trash-free finish prior to seed bed preparation.

Clever layout of hoses

To avoid the risk of hose damage during the turnover operation, the majority of the hoses pass through the main support axle – no hose passes over the turning point of the headstock. Even the valve block is integrated.

Simple and easy

Kubota’s Non-stop system is a very simple construction and yet is able to withstand these punishing forces year in, year out, with a minimum of maintenance.

Legs for the RM2000

The shape of the heat treated hollow square tube and the high under beam clearance enable the plough to handle big amounts of straw and residues. It is very robust but also flexible. Invisible vibrations of the plough beam result in an improvement of crumbling.

Robust frame section

The main frame is an induction heat treated one box section 150 x 150 mm. Hence, the necessary strength and support is achieved for the toughest conditions. No welding is used in order to avoid weaknesses.

Headstock 150

Headstock 150 is designed for tractors up to 150 hp. It features a 'One piece concept' with a specially heat treated 110 Ø main shaft for maximum strength, along with a choice of cross shaft, category II and III, or optional quick coupling.

Constructed for year in, year out performance

For maximum strength and durability, the mainframe of the plough is constructed from only one induction heat-treated box section 150 x 150 mm, with no welding that would weaken the frame's robustness.

Variomat

Kubota Variomat system allows the optimal match between the soil conditions, the plough and the tractor for the maximum output. Kubota's patented Variomat is the most reliable system on the market. It also ensures the correct parallel linkage along the whole plough. The pulling line adjustments are hence automatic. The benefits are easy handling, low draft requirements, and low wear and tear. By varying the furrow width, the work can be kept straighter, making it easier to work up to the hedges and around any obstacles.

Auto-Line

Kubota Auto-line system is a standard device which guarantees the correct pulling line at any time. When changing the working width, both front furrow width and pulling line adjust accordingly. Kubota Auto-line system makes these adjustments automatically. The position of the headstock remains in the center of the tractor, ensuring a favorable and even geometry of the three-point linkage. Consequently, side pull and unnecessary high landside pressure are avoided, ensuring efficient ploughing with less fuel consumption.

Save time and fuel

By changing the ploughing width from 35 to 45 cm, the output increases by 30% with the same plough. This higher performance is achieved at a lesser cost, inducing an 18% reduction in fuel consumption, partly due to the low pulling requirements of Kubota bodies. The Variomat is also the solution to the demanding spring ploughing season when weather conditions are unpredictable, allowing efficiency and quality ploughing to be combined.

A reliable System

The simple multi-leaf spring system allows the plough legs to release over stones and other solid objects in the ground smoothly and efficiently. This avoids sudden jolts and possible damage.

Quality ploughing

Kubota Non-stop system guarantees quality ploughing. The legs release independently from one another, and once the obstruction is passed, the plough body automatically returns to the correct ploughing depth.

Release characteristics

The diagram shows the differences between three different Non-stop systems: Hydraulic system, Coil spring system, and the Unique Kubota leaf spring system, illustrating how the pressure varies as the body rises (1 cm).

Benefits

The Kubota leaf spring Non-stop system is highly recommended. When hitting an obstacle, the pressure on the point, frame, and plough parts decreases, reducing stress on the plough. This guarantees a longer life for the plough and ensures better ploughing.

Extra leaves when needed

The standard Non-stop system includes 7 Kubota heat-treated springs (640 kp). For heavier to extreme soil conditions, extra leaf springs are added for up to 1400 kp.

Kubota RM2000 series

Robust, easy to lift, and to pull, the RM2000 series is economical to run. These ploughs are designed for high performance in light to medium soil conditions. The specific design of the RM2000 series guarantees low lift requirements and easy pulling, which can also be explained by the low weight of the plough due to its compact design, hollow but robust legs, and heat-treated steels requiring less steel width than competitors. The low weight of the plough and the ideal design of the mouldboards contribute to easy pulling and ensure low wear of parts.

Differences between models

The RM2000-RM2000V feature the reliable shear bolt leg protection (3,400 kp), while the RM2005-RM2005V are equipped with the remarkable Non-stop leg protection system for stony conditions.

Kubota RM3000 series

These are compact ploughs, easy to lift, and equipped with the Variomat system to work in any soil conditions.

Smart

The Knock-on system consists of only 2 parts: a holder fixed to a regular Kubota share and a Knock-on point.

Long lasting

Knock-on benefits from Kubota steel technology for low wear. The quality of the steel, combined with a clever design, ensures a long life for the Knock-on system, allowing Knock-on points to be used in any soil conditions.

Quick

Knock-on points can be changed in a few seconds, saving 90% of your time when changing points while working in abrasive soils (where points wear quicker) or when using a 5+ furrow plough.

Agronomic benefits

Knock-on has been tested in several soil conditions. Even in the hardest soils, the points ensure good penetration, keeping the plough stable during work and ensuring quality ploughing results.

Low pulling forces

Kubota bodies generate very low pulling forces. With Knock-on points, the pulling forces remain low, which helps reduce fuel consumption.

Soil flow protection

The clever design of Knock-on actually protects the other parts of the body while allowing efficient soil flow.
