OPERATION
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.
