Super Slope Master

Commercial land clearing slope mower

The Super Slope Master is in a class all its own when it comes to extra heavy-duty commercial steep slope mowing, mowing slopes up to 40° and is the #1 commercial land clearing steep slope mower on the market.

The is heavy duty steep slope mower is designed to cut rough terrain, including heavy grass, weeds, and occasional low brush. It has a powerful 36 HP Yanmar diesel engine and 1/4" steel deck, with three 3/8" cutting blades. The skid steering mechanism feature twin, closed loop hydraulic systems that offer the superior maneuverability and power that is required to mow steep slopes. Machines with steering wheels are not as maneuverable and cannot operate safely on steep slopes.

With the ability to cut at a 40° slope, this true "zero turn radius" machine can trim around objects and mow a swath of 72 inches wide without leaving the slope! It will cut more area in a fraction of the time compared to other machines – and with maximum safety. For safety, if the operator inadvertently leaves the seat the mower is immediately braked. For safety, the operator sits on a tilting seat located at the rear extremity of the machine, positioned to safely exit the machine. For safety, the operator looks forward while operating the machine. The deck supports the chassis from the front, while pivoting side to side to follow the contours of the turf.

The Super Slope Master offers maximum versatility as both a rough cut and a finish cut mower. The standard flat blades are best for rough mowing. Flat blades allow the most powerful cut in heavy growth. The machine can be quickly converted to the optional high lift blades for finish mowing. For the best results, the deck guards are lowered for maximum “lift on the grass” with the added benefit of reduced chances for thrown objects. The standard tractor tread tires can be replaced by the optional turf tread tires when the machine is to be used primarily for finish turf mowing on less steep slopes.


Ability to mow all day without refueling in even the most demanding conditions

Adjustable tilting seat with suspension to keep the operator upright and comfortable

Rear discharge for reduced thrown object risk


Tip up stop to eliminate the machine from rolling over backward

ROPS produces “cone of protection” in the event a machine does roll over sideways
