7. SETTING THE MOWER
After the mower is attached to the tractor’s 3-point hitch, but before the universal slip joint is installed, and with the mower on the ground, adjust the top link of the hitch to make the mower gearbox input shaft parallel to the tractor PTO shaft.
This relationship provides optimum operation of the universal joints in the driveline.
A driveline that is not parallel to the PTO will result in vibration due to the characteristic of a universal joint that results in the output end speeding up and slowing down twice each revolution of the universal jointed shaft.
Adjust the top link whenever the cutting height is changed.
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of uneven terrain.
