Operation - 25 Series Rotary Tiller

Driveline Dimension

A PTO driveline is supplied with the machine. To accommodate the variety of 3-point hitch 

geometry available today, the driveline can be too long for some machines and must be cut.   

It is very important that the driveline be free to telescope but not bottom out when going through 

its working range. If the driveline bottoms out, the bearings on both the machine and tractor PTO 

shaft will be overloaded and fail in a short time. 

If cutting the drive is necessary, follow this procedure:

1.  Clear the area of bystanders, especially small children.

2.  Attach the Tiller to the tractor but do not attach the driveline.

3.  Raise the machine until the input gearbox shaft is level with the Tractor PTO shaft.

4.  Measure the dimension between the locking groove on the tractor PTO shaft and the groove 

on the Tiller input shaft.

5.  Measure the same dimensions on the compressed driveline. 

6.  If the driveline pin to pin dimension (B) exceeds the groove to groove dimension, the driveline 

should be cut.

7.  Pull the driveline apart and cut 1/2 of the dimension determined in step 5 from each end.  Add 

another 1/2" (12mm) to each cut off segment.
