Kuhn RSM Series
Description
KUHN RSM roadside mowers provide the most efficient management of roadsides and ditches. The quality of work and adaptability are two main characteristics of these roadside mowers. They are suitable for tractors with 65 – 90 horsepower and are at ease in a wide variety of conditions. The models in the RSM range has been designed to meet local municipality needs for mowing work with greater safety over conventional rotary mowers.
Models
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.SPECIFICATIONS
