Adjusting the Cutting Unit Rollers
The cutting unit rollers should be mounted in the lower
position when operating in height of cuts greater than
64 mm (2-1/2 inches) and in the higher position when
operating in height of cuts lower than 64 mm (2-1/2
inches).
1. Remove the bolt and nut securing the gage
wheel to the cutting unit brackets

2. Align the roller and spacer with the top holes in
the brackets and secure them with the bolt and
nut.
Adjusting the Blade
To ensure proper operation of the cutting unit,
there must be 10-16 mm (0.38-0.62 inch) clearance
between the tips of the wing and center cutting unit
blades (Figure 28).
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 10-16 mm (0.38-0.62 inch)

3. To adjust distance, locate adjuster bolt on rear
pivot link of cutting unit
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 a sample area of grass be cut and the 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.
2. Check and adjust front and rear tractor tire
pressure to 172-207 kPa (25-30 psi).
3. Check and adjust all castor tire pressures to 345
kPa (50 psi).
4. Check charge and counterbalance pressures
with engine at high idle using test ports defined
in Hydraulic Systems Test Ports. Adjust
counterbalance to 2241 kPa (325 psi).
