Page 93: Cutting Speed
STARTING & STOPPING MOWER Power for operating mower is supplied from tractor PTO. Refer to your tractor manual instructions for engaging and disengaging the PTO. Always engage the PTO at low engine rpm. Always operate at recommended PTO speed of 540 RPM. Learn how to stop tractor and mower quickly in case of an emergency. IMPORTANT: Stop mower and tractor immediately upon striking an obstruction.
Page 94: Driveline Length Check Procedure
DETACHING AND STORING Lower the Mower to the Ground. Park the Tractor with the transmission in the correct gear ( Automatic Trans- mission-- Park; Standard Transmission--Neutral). Set the parking brake, shut off the engine, and remove the key. Wait until the PTO stops rotating before getting down from the tractor . Disconnect the driveline from the tractor PTO and store it to prevent it from contacting the ground.
Page 95 With the PTO NOT TURNING, slowly drive the tractor with mower attached through sharpest turn possible and watch shaft movement. With PTO NOT TURNING, slowly drive the tractor with mower attached through the most severe terrain conditions expected and watch Shaft movement. Check position which places driveline at maximum extended length and at maximum compressed length.
Page 96 If you have a condition where your tractor will be going up a steep incline with your mower still on the flat area or coming down the opposite incline, you have a potential problem. Figure 11. The correct preventive measure is to instruct the operator to cross this kind of terrain at an angle.
Page 97 CV DRIVELINE CHECK PROCEDURES The Main Driveline to tractor is equipped with a special constant velocity (CV) joint that allows the joint to run smooth with no vibration even at joint angles up to 80 degrees.
