Shortening Driveline

1. Move the tiller up and down to get the shortest possible
distance between tractor PTO shaft and gearbox input
shaft. Leave the tiller in the minimum distance position.
Install jack stands under the tiller for support.
2. Separate the driveline into two halves and connect them to
the tractor and the gearbox.
3. Place driveline halves parallel to one another to determine
how much to shorten the driveline.

drive halves slide smoothly together.
Do not run the tractor if proper driveline engagement
cannot be obtained through these methods.
Connect the driveline to tractor PTO shaft, making sure
the spring-activated locking collar slides freely and locks
driveline to PTO shaft.
NOTICE
If attaching with quick hitch, the distance between
the tractor PTO and gearbox input shaft will increase.
Please follow the steps as you would for a 3-point
hitch to insure proper engagement.
