FUNCTIONS PROPERLY
UNLOADING
1. Park forage box on level ground whenever possible during unloading. Lock tractor parking brake.
2. Connect PTO to tractor, locking securely in place. USE 540 PTO ONLY.
3. Engage PTO.
4. To engage cross conveyor INTERMITTENTLY, rotate clutch lever (A) clockwise and hold with hand
pressure. If hand pressure is removed, the cross conveyor will stop.
5. To engage the cross conveyor CONTINUOUSLY, rotate clutch lever (A) clockwise until it locks in the
engaged position. Cross conveyor speed is controlled by tractor RPM only.
6. Quickly engaging/disengaging beaters (lever B) will allow beaters to clear material a little at a time to
avoid exceeding blower capacity.
7. When beaters are clear of material, move control lever (B) to apron speed positions. Variable speed
drive offers you a number of unloading speeds to choose from. With experience and depending on the
type of forage, you will be able to select a speed which will match your blower capacity.
Unloading speed may also be varied by increasing or decreasing engine speed of tractor.
