Figure 46. Checking The Blade Height Measurement
Deck Leveling Adjustment - 72” Models
NOTE: Before adjusting the deck level, the deck lift rod
timing must be checked and/or adjusted.
1. Park the machine on a flat, level surface. Disengage
the PTO, stop the engine and engage the parking brake.
Check tires for proper inflation.
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 43.
4. Loosen the jam nut (A, Figure 45) on the deck hanger.
5. Turn the deck height adjuster (B) clockwise to raise the
deck or counter-clockwise to lower the deck until the
deck rests on the 2 x 4’s.
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 46).
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.
