3.15 LEVELING FRONT MOWER _________________________________________________
1. Before leveling the front deck, the tractor tires and
caster wheels must be properly inflated. The cutting
height is directly related to the radius of the tire.
2. Set the cutting height of the front mower to 5-1/2 in.
(140 mm).
3. Rotate all blades so that one end of the blade (A) is
pointing forward.
4. Fully lower front deck. Measure from the ground to
point (A) and from the ground to point (B) . Point (B)
must be 1/8 in. (3 mm) higher than point (A) .
5. Add or remove shims (C) as required between
bumper pad (D) and lift arm (E) .
6. Once the front mower has been properly leveled,
the cutting height may be readjusted without
changing the shims. It may be necessary to re-level
the deck if there is a change to the tires.
