Deck Leveling Adjustment - 61” Models
NOTE: Before adjusting the deck level, the deck lift
rod timing must be checked and/or adjusted.
Coarse Adjustment Procedure
When adjusting the deck level, the coarse adjustment
procedure should be used to make the majority of the
adjustment and the fine adjustment procedure should be
used to complete the adjustment.
1. Park machine on a flat, level surface. Disengage the
PTO, stop the engine and engage the parking brake.
Rear tires must be inflated to 15 psi (1,03 bar); front
tires to 25 psi (1,72 bar).
2. Lock the deck lift pedal in the 6” (15,2 cm) position.
Place the deck height adjustment pin in the 4” position
and lower deck the lift pedal until the arm contacts the
pin.
3. Place 2 x 4 blocks under each corner of the mower deck
with the 3-1/2” sides being vertical. See Figure 38.
4. Loosen the nuts and allow the front of the deck to rest
on the 2 x 4’s. Slide the chains down in the slots until
the chains are tight and tighten the nuts See Figure 39.
5. Loosen the nuts and allow the rear of the deck to rest on
the 2 x 4’s. Slide the chains down in the slots until the
chains are tight and tighten the nuts. See Figure 39.
6. Remove all 2 x 4 blocks from under the mower deck.
7. For your safety, DO NOT handle mower blades with bare
hands. Position the outside mower blades so that they
face front-to-back (Figure 40).
8. Measure from the front tip of the blade from the cutting
edge to the ground. Measure from the rear tip of the
blade from the cutting edge to the ground. Repeat this
process for the other side of the machine. The front
and back measurements should be 4” (10,2 cm). If the
measurements are greater than 1/8” (3,17 mm) of what
they should be adjust the deck height until they are
correct.
Fine Adjustment
1. Loosen the jam nut (A, Figure 41) and turn the fine
adjustment bolt (B) to adjust the deck height until the
front measurements equals 4” (10,2 cm). Turn the bolt
CLOCKWISE to raise the deck; COUNTER-CLOCKWISE
to lower the deck.
2. Position the outside mower blades so they face front-to-
back.
3. Remeasure the front tip of the blade from the cutting
edge to the ground. Measure the rear tip of the blade
from the cutting edge to the ground. Repeat the
process for the other side of machine.
4. Once the measurement equals 4” (10,2 cm), retighten
the jam nut.
