Oscillating Main Frame

An oscillating main frame, with floating pivot on the mowing head, allows the mowing head to adapt to the conditions and environment around it.

Rear Roller

The 6” diameter rear roller provides optimal height control, eliminates ruts in loose soils and provides better clearance over irregular ground.

Vertical Lift

The vertical lift automatically compensates for uneven ground. The models in the RSM range can mow on a higher plane than the road level. The vertical lift function also makes it easier to mow shallow ditches while maintaining an optimal drive position.

Heavy-Duty Belt Drive

The RSM utilizes a belt drive system built to handle heavy service. Its position keeps the PTO shaft as straight as possible, while the ventilated guard reduces heat buildup, extending the life of the belt.

Mechanical Safety Breakaway System

A mechanical safety breakaway system protects the mower from inadvertent encounters with obstacles. Simply back the tractor up to reset and continue mowing.

Structure of the Chassis and Frame

The structure of the chassis and frame are based on KUHN’s decades of experience with mowers and shredders. In the event of a collision with an obstacle, the mechanical safety device will protect the machine’s structure. Hydraulic non-stop protection is available as an option.
