1-2 DESCRIPTION

The 280 Series rotary cutters (Figure 1-1) are
designed for medium duty applications such as
grass, corn stalks and light brush. These cutters are
single spindle with two free-swinging blades. Free-
swinging blades reduce the shock of impact when a
stationary object is hit. Additional protection is pro-
vided by a slip clutch on the gearbox input shaft. A
round blade holder allows the cutter to "ride over"
stumps and similar immovable objects. Models 285
and 286 are attached to the tractor using a standard
Cat. I or II 3-point hitches. The 287 can use Cat. I
and II standard and quick hitch or semi-mount.
Standard equipment includes driveline shields,
clutch shields and front and rear discharge shields
