Tow Cable Installation
1. Add 2 spacers in between the cable holder and
the tractor frame by the front tires. Use a 5/8” x 6”
bolt (PN: 16-20200), 2 - 5/8” washers
(PN: 57-20746) and a 5/8” top lock nut
(PN: 70-20646) on each side (1).
2. Install the front cable support bracket at the front
of the undercarriage. Install with 3 spacers on each
side in between the undercarriage and the bracket.
Use 3 - 20mm x 120mm (PN: 16-2489) to install the
bracket and undercarriage. Use the same washers
and nuts that were used in the mounting instructions
on Page 5 (2).
3. Route the cable underneath the undercarriage, then
over the cable support and under the undercarriage on
the right side (3).
4. Install the original bracket to the side of
the undercarriage with 2 - 3/4” x 2” bolts
(PN: 16-20218) and 2 - 3/4” nuts
(PN: 70-20607). Cable clamp is installed in
Step #6.
5. Finish routing the cable under the lift frame and up
over the cable bracket. Attach to the bracket with the
original hardware (4).
6. Pull the cable so there is some slack at the front
under the lift frame as shown in the picture above. Then
put a cable clamp up by the side bracket as shown in
the picture from Step #4 to keep the cable in place.
Note: Your undercarriage may vary slightly from the one shown in the pictures below, but the same
installation procedure will be compatible.
