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. This joint will operate and perform satisfactorily
as long as it is not subjected to conditions which abuse it or go beyond its operating limits.
1. The constant velocity joint must be greased daily at 8 hour intervals. See Maintenance Section. Failure to
lubricate as instructed will cause rapid wear and failure of operating components of joint.
2. The constant velocity joint must not be subjected to a joint angle greater than 80 degrees. FIGURE 12.

To check maximum joint angle, connect mower to tractor. Do not connect driveline at this time. Start tractor and
make a maximum turn to left until tractor tire almost contracts frame. Then check joint by holding driveline yoke
above PTO shaft and then angle driveline yoke until it stops. There should be approximately a 10 degree
difference between center line of yoke and PTO shaft. FIGURE 13. If not, check drawbar length and shorten if
necessary or move rear tractor tires wider apart to limit turning radius.
3. The constant velocity joint must also not be subjected to conditions where telescoping tubes bottom out.
Check this condition at same time maximum angle was checked above. There should be at least 4 inches of
additional telescoping available with the yoke attached to the tractor.
NOTE: If the driveline will not connect because it does not have enough clearance; check to see if drawbar can
be lengthened or cut the driveline shield and tube lengths to provide adequate clearance.
