Adjusting the Blade

To ensure proper operation of the cutting unit,
there must be 0.38-0.62 inch (10-16 mm) clearance
between the tips of the wing and center cutting
unit blades (Figure 24).
1. Raise cutting unit so blades are visible and
block center deck section so it cannot fall
accidentally. Wing decks must be horizontal
to center cutting unit.
2. Rotate a center and adjoining wing blade
so there blade tips are aligned. Measure
distance between blade tips, distance should
be approximately 0.38-0.62 inch (10-16 mm)
(Figure 24).

3. To adjust distance, locate adjuster bolt on rear
pivot link of cutting unit (Figure 25). Loosen
jam nut on adjuster bolt. Loosen or tighten
adjuster bolts until 0.38-0.62 inch (10-16 mm)
clearance is attained, then tighten jam nut.
4. Repeat procedure on opposite side of cutting
deck.

Correcting Mismatch Between Cutting
Units
Due to differences in grass conditions and the
counterbalance setting of the traction unit, it is
advised that grass be cut and appearance checked
before formal cutting is started.
1. Set all cutting units to the desired height of cut;
refer to Adjusting the Height of Cut table in
Specifications, page 18.
2. Check and adjust front and rear tractor tire
pressure to 25-30 psi (172-207 kPa).
