Setting the Front-to-Rear Pitch
1.
Check the tire pressure.
2.
Position the blades front-to-rear (Fig. 29).
Measure at “C” and “D” locations (Fig. 29) from
a level surface to the cutting edge of the blades
(Fig. 30).
3.
The mower should be 1/8”–5/8” (3–16 mm)
lower in front “C” than in the rear “D”.

4.
To change the front-to-rear pitch, remove the
retaining ring and move an equal number of
thrust washers on both castor wheel forks. Move
the thrust washers from the top of the carrier
frame mounting tube to the bottom to raise the
front of the mower. Move the thrust washers
from the bottom of the mounting tube to the top
to lower the front of the mower (Fig. 36).
5.
Check the side-to-side leveling of the cutting
unit.
Setting the Side-to-Side Leveling
1.
Check the tire pressure.
2.
Position the blades side-to-side (Fig.31 ).
Measure at “A” and “B” locations (Fig. 31) from
a level surface to the cutting edge of blades
(Fig.32).
3.
The difference between measurements “A” and
“B” should be no more than 1/4” (6 mm).

4.
To change the side-to-side leveling, remove the
retaining ring and move the thrust washers on
one castor wheel fork only. Move the thrust
washers from the top of the carrier frame
mounting tube to the bottom to raise the
corresponding side of the mower. Move the
thrust washers from the bottom of the mounting
tube to the top to lower the corresponding side of
the mower. (Fig. 36).
5.
Recheck the front-to-rear pitch of the cutting
unit.
