ABSTRACT:
A rotary blade type cutting system for cutting grass or the like at a uniform height either on a flat surface, an inclined surface, or along the border adjacent a surface depression. The system is especially useful for cutting the bordering grass around golf course sand traps. The cutting system is pivotally attached to a motorized tractor and comprises a blade housing which contains the cutting blades, a plurality of support members for connecting the housing to the tractor such that the attitude of the housing (the plane of the cutting blade) with respect to the tractor is variable about the center line, longitudinal axis relative to the tractor, an adjustable guide roller connected to the housing to maintain the cutting blades at a predetermined height above the ground, a drive train for transmitting mechanical power from the motor of the tractor to the cutting blades, and a control arm having one end connected to the housing distal of the longitudinal center line of the tractor, positioned adjacent the operator's compartment of the tractor, such that the operator can manually tilt the blade housing. A portion of the housing extends laterally beyond the outside of the wheels so that the tractor can remain on the substantially flat portion of the ground while the housing is tilted to cut the grass along the inclined portion of the ground or along a flat segment that drops off sharply (around a pit or depression).
