MAINTENANCE
CORRECTING CUTTING UNIT MISMATCH
If one cutter blade cuts lower than the others, correct
as follows:
1. Park mower on a level surface. Turn PTO switch
OFF, turn engine OFF, engage parking brake and
disconnect spark plug wire(s).
2. Adjust tire pressure in all tires to specifications and
check that blade(s) are not bent: refer to Checking for
Bent Blade.
3. Place heightofcut to the 21/2 in. position: refer to
Adjusting HeightOfCut. Make sure heightofcut pins
are resting on frame cushions.
4. Rotate blades so tips line up with one another. Tips
of all adjacent blades must be within 1/8 in. of each
other. If tips are not within 1/8 in. of each other add
shims Part No. 325624 between spindle housing and
bottom of cutting unit to align blade(s).
FronttoRear Pitch
1. Position blade(s) fronttorear (Fig. 14). Measure at
C" and D" locations (Fig. 14), from level surface to
the cutting edge of blade(s) (Fig. 15).
2. Mower should be 1/8 in.-5/8 in. lower in front C"
than rear D".
3. To change fronttorear pitch move equal number
of thrust washers on both front castor shafts. Move
thrust washers from top to bottom to raise, or bottom to
top to lower pitch (Fig. 16).
4. Check sidetoside level of cutting unit.

SidetoSide Leveling
1. Position blade(s) sidetoside (Fig. 14). Measure at
A" and B" locations (Fig. 14), from level surface to the
cutting edge of blade(s) (Fig. 15).
2. The difference. between measurements A" and
B" should be no more than1/4 in.
3. To change sidetoside leveling move thrust
washers on one front castor shaft only. Move thrust
washers from top to bottom to raise, or bottom to top to
lower (Fig. 16).
4. Recheck fronttorear pitch of cutting unit.
