Adjusting the Rollers
Note: If the cutting unit is to be used in the 25 or 38 mm (1
or 1-1/2 inches) height-of-cut setting, the cutting unit rollers
must be repositioned in the top bracket holes.
1. Remove the cotter pins securing the roller shafts to
the underside of the deck.
2. Slide the shafts out of the lower bracket holes, align the
rollers with the top holes, and install the shafts.
3. Install the cotter pins to secure the assemblies.
Adjusting the Skids
Adjust the skids by loosening the flange nuts, positioning the
skids as desired, and tightening the flange nuts (Figure 13).

for eyes, ears, feet, and head is recommended.
CAUTION
This machine produces sound levels in excess of
85 dBA at the operator's ear and can cause hearing
loss through extended periods of exposure. Wear
hearing protection when operating this machine.

Mow When Grass is Dry
Mow either in the late morning to avoid the dew, which causes
grass clumping, or in late afternoon to avoid the damage
that can be caused by direct sunlight on the sensitive, freshly
mowed grass.
Select the Proper Height-of-Cut Setting
to Suit Conditions
Remove approximately 26 mm (1 inch) or no more than 1/3
of the grass blade when cutting. In exceptionally lush and
dense grass you may have to raise the height-of-cut setting
another notch. When cutting in 25 or 38 mm (1 or 1-1/2
inches) height-of-cut, add a second washer between the rear
castor forks and the bottom of the castor arm housings to
increase the blade rake.
Mowing in Extreme Conditions
Air is required to cut and recut grass clippings in the mower
housing, so do not set the height-of-cut too low or totally
surround the housing by uncut grass. Always try to have one
side of the mower housing free from uncut grass, allowing air
to be drawn into the housing. When making an initial cut
through the center of an uncut area, operate the machine
slower and back up if the mower starts to clog.
Always Mow with Sharp Blades
A sharp blade cuts cleanly and without tearing or shredding
the grass blades like a dull blade. Tearing and shredding
causes the grass to turn brown at the edges which impairs
growth and increases susceptibility to diseases. Make sure that
the blade is in good condition and a full sail is present.
Check the Condition of the Deck
Make sure that the cutting chambers are in good condition.
Straighten any bends in the chamber components to ensure
correct blade tip/chamber clearance.
Stopping
If the machine has to be stopped while cutting, a clump of
grass clippings may be deposited on the lawn. Follow this
procedure for stopping while cutting
1. With the deck engaged, move onto a previously cut
area.
2. Shift to neutral, move the throttle control lever to the
Slow position, and rotate the ignition key to Off.
After Operating
To ensure optimum performance, clean the underside of the
mower housing after each use. If residue is allowed to build
up in the mower housing, cutting performance will decrease.
