LEVELING THE DECK
1. Set all tire pressures to the correct specifications.
2. Place machine on a level slab of concrete.
3. Depress the deck lift pedal raising the deck to
the full lift height position and move the height
adjustment pin to the 5” position.
4. Place a level on the deck, from front to rear. If
the level is too short to reach all the way from
front to rear, lay a straight edge on the deck first,
then place the level on the straight edge.
5. Lay a .125” spacer beneath the front of the level.
6. Adjustment may be made by loosening the
upper chain fasteners and moving the fasteners
in the provided slot. Adjust fasteners until the lev-
el’s bubble is centered. Repeat for the other side.
COUNTERBALANCE SPRING
Raise the cutter deck to the transport position.
Adjust the spring length with the nuts on the eye-
bolt, located under the seat, to the following lengths
for 3” cutting Heights:
55” Deck - Spring Length of 10-1/2”
61” Deck - Spring Length of 11”
73” Deck - Spring Length of 11”
For lower cutting height, loosen spring at 1/4” inter-
vals until stop hits adjusting pin in correct height
location. If deck floats, loosen spring at 1/4” interval
until deck stops floating. (Measure from inside of

DECK BELT REPLACEMENT
Belt adjustment should be checked every 50 hours
to get maximum life and cutting performance from
the mower. Belt tension is adjusted by increasing or
decreasing the length of the spring on the movable
idler. For proper belt tension on the 55”, 61” and 73”
mowers, the spring length should be set to 7-1/2”
inside hook to inside hook with the deck in 3” cutting
height position. To adjust the spring length, loosen
or tighten the 3/8” hex nuts on the eye bolt until the
correct spring length is reached.
DECK BELT REPLACEMENT
USE ONLY GENUINE BUSH HOG REPLACEMENT PARTS
A. Remove the deck shield assembly.
