Keep hands and feet out from under the mower and clear of pinch points between the tractor and mower Always shut the Tractor completely down, place the transmission in park, and set the...
OPERATION 6.1 Connecting Mower Hydraulics 1. With the tractor shut down and secured in position, move the hydraulic remote valve lever back and forth several times or place the hydraulic lever in the float position to relieve all hydraulic pressure. When connecting the mower hydraulic lines to the tractor, keep the hose, quick couplers, and swivels free of dirt and other contaminants.
OPERATION 7. SETTING MOWER CUTTING HEIGHT Properly setting the cutting height is essential for efficient and safe operation. A properly set mower makes a more uniform cut, distributes clippings more evenly, increases tractor efficiency, and follows the contour of uneven terrain. Note: Avoid very low cutting heights, striking the ground with the blades gives the most damaging shock loads and will cause damage to the mower and drive.
OPERATION 8. DRIVELINE ATTACHMENT The driveline yoke and tractor PTO shaft must be dirt free and greased for easy and secure 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 60
OPERATION “Bottoming Out” Check Procedure” 1. Disconnect driveline from the tractor and slide profiles together until fully compressed. 2. Place a mark on the inner shield 1/8” from the end of the outer shield and reattach the driveline to the PTO shaft. 3.
OPERATION 5. If the engaged length is less than 8”, the shaft is considered too short and should be replaced with a longer shaft. Consult an authorized dealer to purchase the required driveline length. NOTE: If the driveline cannot be shortened and still maintain the required profile engagement, the operator must be made aware of terrain conditions and avoid situations which pose a potential problem to avoid damaging the driveline.
