CARE AND MAINTENANCE - 5000 SERIES MODELS
MOWER DECK LEVELING PROCEDURE:
There are a total of (4) threaded adjusters which will control the attitude or pitch of the mower deck.
The adjusters have lock nuts on the bottom which can be turned up or down to raise or lower the front
and rear of the mower deck. Deck should be level or pitched slightly higher in rear.
A. Place the mower on a smooth level surface, check tire pressures to insure the
mower has a correct stance. Inflate tires as required:
Front: 16 - 21 lbs maximum
Rear: 8 -14 lbs maximum
B. Rotate or turn each outer blade tip to align with the edge of the deck or side to side.
C. Measure from the surface up to the bottom of the blade tip on the discharge side
of the mower deck. Retain this measurement. Move to the opposite side, check that
measurement is the same. If adjustment is required, turn the nut on the bottom of
the front threaded adjuster up or down until both side to side measurements are
equal. Retain measurement.
D. Rotate or turn both outer blades to align with the deck in front to rear manner. Move
to the left rear threaded adjuster, "left rear is designated from operator position on
the mower". Turn adjuster nut up or down until rear of mower deck is positioned level
to 1 /8th of an inch higher than the side to side measurement. At this time, the mower
deck will hang or be suspended on (3) points (both front adjusters and the left rear
adjuster). Move the right rear adjuster and take out the slack which will be present
by turning adjuster lock nut up. Confirm the measurement used on the left rear of
the deck.
NOTE: This will place the mower deck in a base measurement position. Additional
adjustment may be required to achieve desired cut for the type of grass or
conditions being mowed.
