caster wheels must be properly inflated. The cutting
height is directly related to the radius of the tire.

(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

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.
