MOWER DECK LEVELING
ADJUSTMENT
1. Place the cutting height quick pin in the 4” setting.
2. Measure the front and back edges of the mower
deck. It should measure 4-1/2” (11,4cm) from the
ground to the front lower edge of the mower deck
and 3-5/8” (9,2cm) from the back lower edge to the
ground. These measurements should be made par-
allel to the frame of the tractor, in-line with the outer
blade spindle housings on both sides of the mower
deck (see Figure 32)
3. If the measurements taken do not match the dimen-
sions specified, adjust the front and rear hanger
assemblies.
4. Using a 3/4” wrench and socket, adjust the front and
rear hanger assemblies (Figure 33) until the meas-
urements are achieved, making sure the deck lift
pedal arm is still resting against the quick pin.
