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
