Easily Adapt to Mowing Conditions

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.

Knife Options

  • Articulated Hammer Knives
    Create lift for a clean cut. The shackle allows more freedom to clear obstructions hidden in grass conditions.
  • Hammer Knives
    Hammer knives are designed for shredding with plenty of lift and extra weight to power through brush up to 2”. Not for use in rocky conditions.



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.



Close Coupling
The specially designed headstock keeps the mower as close to the tractor as possible, offering outstanding controllability in both the mowing and transport positions.
