There are two electrical wires (red and white) that come
wrapped around the three-point PTO connector.
• connect the red wire to a 12-volt power source, such
as the alternator or the battery.
• Ground the white wire (connect to negative post on
the battery or another point).
The driveline supplied with this machine may need to be
cut to a shorter length for proper operation with the tractor
being used. To determine if driveline will need to be cut,
follow steps below or consult attached driveline manual.
1. BeFore aTTaCHInG THe DrIVelIne: attach the
machine to the tractor with three-point hitch system.
2. Raise and lower machine on three-point hitch to determine
the shortest possible working distance between the tractor
PTO shaft and the drive shaft of the machine.
3. Pull the driveline apart so the two pieces are separated.
connect the piece with 6-splined connector to tractor
and the other piece to the machine.
4. Position installed driveline halves parallel to one another.
(Photo below is example of driveline overlap.)

screws in the owner’s kit.
