Keep hands and feet from under the shredder ends and clear of pinch points between the tractor hitch arms and shredder pins.
  • Page 117 OPERATION 8. DRIVELINE ATTACHMENT The driveline yoke and tractor PTO shaft must be dirt free and greased for attachment. To connect the mower driveline to the tractor PTO output shaft, pull the driveline yoke collar back and align the grooves and splines of the yoke with those of the PTO shaft.
  • Page 118 OPERATION 8.1 Driveline Length Check Before operating the Implement, check to make sure the Implement input driveline will not bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and through the support bearings or downward onto the PTO shaft, breaking it off.
  • Page 119 OPERATION 9. PRE-OPERATION INSPECTION AND SERVICE Before each use, a pre-operation inspection and service of the implement and tractor must be performed. This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped and functional, and performing needed repairs.

DRIVING THE TRACTOR AND IMPLEMENT Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight of the implement and the tractor operating controls are set for safe transport.
  • Page 126 OPERATION 10.1 Starting The Tractor The procedure to start the tractor is model specific. Refer to the tractor operator’s manual for starting procedures for your particular tractor. Consult an authorized dealer if the starting procedure is unclear. Ensure the 3-point control lever is in the lowered position and the PTO is disengaged before starting the tractor.
  • Page 127 OPERATION 10.3 Raising the Shredder Using the tractor 3-point hitch control lever, raise the shredder off the ground about 6”, or just high enough to clear any ground obstacles. When raising the shredder, make sure all connection points are securely attached and at least 1” clearance is maintained between the driveline and the deck.
  • Page 128 OPERATION 10.5 Turning Procedure Pull-type Units - Pull-type units are fitted with a constant velocity joint at the tractor hitch to allow operating during turns. Do not disengage PTO and end of row. Reduce speed and RPM slightly and proceed with turn. Make wide turns to reduce load on driveline caused by high joint angles.
  • Page 129 OPERATION When confronted with an incline or ditch, do not approach from an angle which is perpendicular or straight on as damaged to over collapse of the driveline may occur. When crossing such terrain, the implement should be fully lowered for a lower center of gravity and added stability.
  • Page 130 OPERATION 11. OPERATING THE TRACTOR AND IMPLEMENT THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE.
