1. Park the machine on a level surface, lower the
cutting unit, engage the parking brake, shut off
the engine, and remove the key.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Adjust the anti-scalp rollers as shown in Figure
13 .
Note:
Select a hole so the anti-scalp roller
is positioned to the nearest corresponding
height-of-cut desired.

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.
1. Park the machine on a level surface, lower the
cutting unit, engage the parking brake, shut off
the engine, and remove the key.
2. Set the cutting unit to the desired height of cut;
refer to
Adjusting the Height of Cut (page 11) .
3. Check and adjust the front and rear traction-unit
tire pressure to the specified tire pressure in the
traction unit
Operator’s Manual .
4. Check for bent blades; refer to Checking for a
Bent Blade (page 19) .
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
Adjusting
the Height of Cut (page 11) .
8. 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
Adjusting the
Cutting-Unit Pitch (page 12) .
11. Adjust the castor-wheel spacers to match the
height of cut listed on the castor-wheel decal;
refer to
Positioning the Castor-Fork Spacers
(page 11) .
Operating Tips
Fast Throttle Setting/Ground
Speed
To maintain enough power for the machine and deck
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.
