Correcting a Cutting Unit
Mismatch
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.

5.
Cut grass in a test area to determine if all cutting
units are cutting at the same height.
6.
If cutting unit adjustments are still needed, find a
flat surface using a 2 m (6 ft) or longer straight

edge.
7.
To ease measuring blade plane, raise the height
of cut to the highest position; refer to
the Height of Cut (page

Lower cutting unit onto the flat surface. Remove
the covers from the top of the cutting units.
9.
Rotate the blade on each spindle until the ends
face forward and backward.
10.
Measure from the floor to the front tip of the

cutting edge.
If the measurements do not match the desired
height of cut and pitch, refer to

Operating Tips
Fast Throttle Setting/Ground
Speed
To maintain enough power for the machine and deck
g296902
while mowing, operate the engine at the fast throttle
position and adjust your ground speed for conditions.
Decrease the ground speed as the load on the cutting
blades increases. Increase the ground speed as the
load on the blades decreases.
Mowing Direction
Alternate mowing direction to avoid making ruts in
the turf over time. This also helps disperse clippings
which enhances decomposition and fertilization.
Cutting Speed
To improve cut quality, use a slower ground speed.
