HEAVY-DUTY COMPONENTS

Heavy-Duty Components for Long Service Life

Masterdrive® GIII Gearbox

The patented KUHN Masterdrive GIII double-reduction gearbox is designed for heavy crops, tough field conditions, and intensive use. Key components have been improved to build lighter, yet stronger rotors such as: aluminum alloy housings, optimized cam track minimizing force on the follower bearing, larger follower bearing diameter reducing rotation speed and pressure on the cam, tine arms with large-dimension bearings, sturdier pivoting tine support shaft, reinforced main shaft, and reinforced mounting of tine arms on tine holders. The Masterdrive GIII’s ability to move heavy wet crop, handle dry hay gently, and neatly windrow corn stalks is unrivaled in the industry.

Double-Curved Tine Arms

Double-curved tine arms are designed to form fluffy and straight windrows for superior raking quality at high speeds. Fluffy windrows allow more air movement through the crop promoting fast and uniform drying!

KUHN rotary rakes achieve this by following two basic principles for ideal windrow formation. First, the tine arms maintain a positive forward position right up to the point where the forage is delivered to the windrow ensuring gentle crop handling and minimal ash incorporation. Second, a steep cam track allows the tines to be raised very quickly to provide additional clearance over the windrow.

3D Suspension

Suspended on an articulation joint and independent from the main frame, the rotors can pivot in all directions allowing close ground following over undulating terrain. The tines collect the crop with the greatest precision.

Jet Effect

A hydraulic cylinder at the front of the rotor head controls the “touchdown” when lowering the rotor. In a similar way to an airplane, the rear touches first with the front following. This ensures that the tines to do not contact the soil.

EASY WORKING ADJUSTMENTS

Quick and Easy Working Adjustments

Smart Headland Management

For easy and efficient headland turns at the end of the field, an automated pre-programmed headland sequence can be utilized on the ISOBUS monitor. The headland sequence can be adapted to specific needs and thanks to angle sensors, the rotors will always be raised to the pre-defined height regardless of working width. Once all pre-adjustments are done, you only need to press a button, then sit back and let the electronics do the work.

Adjustable Working Width

The working width is adjusted from the ISOBUS monitor, making this adjustment easy for the operator. The front rotors can be moved independently from the rear rotors to choose a desired working width. Then adjust your rear rotors to create a windrow width to best match your harvesting equipment.

Raking Height Adjustment

The raking height is easily adjusted from the operator’s seat. This can be done simultaneously for the two front or the two rear rotors, as well as individually for each single one. The current height is indicated both on the terminal’s display and the rotor undercarriage.

INCREASE YOUR WORKING POWER

Hydraulics to Increase the Machine’s Working Power

Self-Contained Hydraulic Unit

The hydraulic unit of the GA 13131 and GA 15131 is mounted on the pivoting headstock of the machine frame. In this way the primary drive shaft is always perfectly aligned to the tractor, even in tight corners. Moreover, you can adapt the PTO speed from the cab according to type and volume of forage. The hydraulic drive considerably simplifies the machine and provides multiple solutions for improved work.

Hydraulic Rotor Drive

The hydraulic rotor drive, with only one primary drive shaft, reduces maintenance to a minimum. You can finally forget daily lubrication of secondary drive shafts and save up to one hour compared to a mechanically driven rake of the same size. When forage has to be quickly brought in before the next rain, this can make the difference.

Stabilift™ 3D Suspension Lock

Both 3D suspension rotors are equipped with an integrated hydraulic cylinder, which locks the rotor movement automatically as soon as a rotor is lifted from the ground. The main advantages of this system include:

  • Lower the machine’s center of gravity for more stability
  • Higher ground clearance for windrow

 

Headstock Suspension

The 2-point hitch, with integrated suspension, provides increased flexibility while driving, and greater stability between the tractor and rake during turns. This improves the performance on rough roads and provides jolt-free driving through corners, as well as in the field when the rotors are lifted only on one side.

Boost Function

From the ISOBUS monitor, the rotation speed of the front rotors can be increased by 20% compared to the rear rotors. The boost function projects the forage toward the center of the machine, spreading the forage across the width of the rear rotor. This puts less stress on the rear rotor, allowing them to create a fluffy and uniform windrow. This is ideal for perfecting the forage drying process.
