Vari-Master L OL 4E T Kuhn Vari-Master L OL 4E T Specifications & Technical Data (2020—2026)

Mouldboards with Unequal Layer Triplex Steel

KUHN mouldboards are made of unequal layer Triplex steel. The thickness of the wearing surface is increased to 3.3mm - an exclusive feature.

Share Points

KUHN share points are forged and treated to make sure they deliver optimum ploughing performance all throughout their service life. The material is concentrated in the high-wear areas on the point. Plus, the high quality steel on KUHN points ensures durability. KUHN has developed a range of carbide points to give you five times the life of a traditional share point. The optimised profile on the KUHN carbide points features thicker plates at the back of the share where most of the wear happens.

Semi-marathon

For stony soil, its shape guarantees a continuous penetration and avoids ejecting rocks. It offers more resistance than a duck beak share.

Super Marathon

Special heat treated forged steel fitted with a tungsten carbide tip. It provides high wear resistance and offers four to five times the life of a traditional share point. A sharp working edge is maintained for excellent ground penetration.

Ploughing Versatility

You can plough both in-furrow and on-land, making the machine extremely versatile and increasing your options. The on-land system provides high quality ploughing with tractors equipped with wide tyres (≥800 mm) or even tracks.

Safe-T Leg Protection

Abrupt breakage of the 16mm traction bolt following a force at the plough point in excess of 4000kg avoids risk of too frequent a breakage. The bolt runs in the direction of the line of force contrary to the conventional scissor bolt method where the bolt runs across the line of force. Due to these “in-line” forces the bolt support never deforms and never becomes rounded with use. It is impossible for the bolt A to become trapped inside following a breakage. Once a force in excess of 3000kg is met at the furrow point, the bolt breaks along its length and simply falls away for quick and easy replacement. Even after many bolt breakages the plough bodies remain at an identical depth and perfectly in-line.

Flexibility

The VARI-MASTER L benefits from the «Pro-Set» system for a simple start-up. The settings grouped in the middle part means all the tyres on the market from 1.15 m to 1.60 m can be rapidly adapted. The indicator is visible from the cabin. With the «Pro-Set» system, the user is guaranteed perfect alignment at work thanks to the possible tilt correction, limiting wear and facilitating traction.

The Headstocks

The headstock of the VARI-MASTER L is available in category 3N, 3 and 4N. With fixed coupling hands, it is simple to couple the plough and easy to adjust the height of the lower coupling points to maximise the tractor’s traction.

Skimmers for Soil Management

KUHN offers a wide selection of skimmers for better trash burial and soil turning. Depending on the type of soil and crop, the skimmer you choose will determine the ploughing quality.

Depth wheels

Control the depth working. High diameter for a good stability. Available in 690x320 and 760x370 mm. Mechanical adjustment without tools or hydraulical adjustment controlled from the cab.

Adjustable skimmer «KUHN patented system»

Just one movement lets you choose the correct angle to adapt to the speed and depth for total incorporation of vegetation.

EasyDrive headstock

The EasyDrive headstock makes it easy to switch between work/transport position. No more need to unhook and disturb the 3rd point for setting into road position.

OptiDrive headstock

As well as simplifying work/transport transition, the OptiDrive headstock provides a shock absorption system. Fully integrated into the structure of the headstock, the suspension significantly improves driver comfort during the turnaround and transport phases while protecting the plough and the tractor.

Hydro-Safe Leg Protection

Designed for stony and/or heavy conditions the Hydro-Safe system allows continuous ploughing with the plough legs automatically folding out of work upon hitting an obstacle and immediately returning into work again once the obstacle is passed. No need to get out of the tractor and no need to replace bolts. The system also acts as an excellent shock absorber when working in pebbly or flinty ground absorbing all the vibration, increasing the life of the plough and increasing comfort for the driver.

VARIBAR system

VARIBAR system: An optional system allowing instant control from the tractor cab of the Hydro-Safe pressure at the share point - either with or without Maxibar.

MAXIBAR system

MAXIBAR system: The Maxibar option allows the pressure at the share point to be increased giving an adjustment range of 600 to 2500kg yet conserving the flexibility of the system. The option is particularly useful in heavy compacted ground.

3D-Skim

A new setting parameter for improve the burying: «3D-Skim» intuitive adjustement of the skimmer attack angle. Quick adaptation without tools at all conditions. Just one manipulation to adjust working depth and angle of attack. An ergonomic shape to facilitate the flow of residues.

Limited Overhang

Completely independent of the number of bodies, the overhang of the side wheels is controlled. The double attachment lets you move the wheel forward or backward for less overhang or more stability. The new arched plough beam causes less wheel overhang, in order to work as close as possible to the edges of the field and provide a clean finish.

Combined Side Wheel

This wheel ensures little overhang while offering a dual function: a working position to regulate the depth and a second position for safe road transport.
