(76 mm) cutting height location.
6.
Release the transport lock and allow the deck to
lower to the cutting height.
7.
Raise the discharge deflector (side discharge units
only).
8.
Measure from the level surface to the front tip of
the center blade. The measurement should read
3 inches (76 mm).

side blades should be adjusted:
Side Discharge Units: 1/4 inch (6.4 mm) higher
than the front.
Rear Discharge Units: to be level with the front.

height. Tighten all the nuts on the deck lift arm
assemblies.
12.
Lower discharge deflector (side discharge units

desired rake, the single point adjustment can be
utilized to gain more adjustment (see Figure 45).
