Attaching To The Tractor – PTO Length
Before fitting the PTO for the first time, it may be necessary to adjust the length.
There should be maximum engagement of the sliding tubes without bottoming at the
shortest operation position. To check, first connect the mower to the tractor. Pull the
PTO shaft apart and connect to the tractor PTO output shaft and the gearbox input
shaft. Hold the half shafts next to each other in the shortest working position. If
necessary, shorten the inner and outer guard tubes equally (Fig. 1). Shorten the
inner and outer sliding profiles by the same length as the guard tubes. File all sharp
edges and remove burrs. Grease sliding profiles.
To fit the PTO, first clean and grease. Press locking pins on the yoke and
simultaneously push the PTO yoke onto PTO stub shaft of the tractor until pins
engage, check PTO input shaft is secure.
The PTO shaft is fitted with a non-rotating safety guard. It should be secured to the
machine and tractor with the two retaining chains provided.
Note:
Inspect the tractor PTO stub for damage/wear as this may affect the
attachment/removal of the Spearhead input shaft. Check also for alignment as any
concentricity will cause vibration and premature wear of the wide angle joint.
