Service Dealer’s Guide to Great Quality of Cut 4 - 19
Checking and Adjusting the Blade Level
An alternate way to check this is to remove the mower
housing and turn it over. Remove the blades and lay a
straight edge on two blade saddles (Figure 59). It
should lie flat. If not, either the spindle or the housing
where the spindle mounts may be bent.

Yet another way to check this with the blades attached
is to align the blades (two blades at a time on three
blade mowers), then run a string across the cutting tips
of the blades. The string should be straight. If it is not,
the blade or spindle could be bent.
If the saddles or blades do not line up and the spindles
are not bent, a shim between the spindle housing and
the mower housing may help align them. Loosen the
spindle to mower housing bolts and insert shim
washers until the saddles are in line. Then if you used
washers to shim the spindle housing, remove the bolt
and reassemble through the washer to secure it.
300-400-500 Series Garden Tractor
(Excluding 5xi Series)
The mower attachments used on these tractors all
have the side-to-side level and the height of cut
determined by the rear gage wheels (Figure 60).

Adjusting Side-to-Side Level
If the mower does not cut level side-to-side, check for a
worn out gage wheel, a bent gage wheel support, or
improperly tracking blades. Finding and correcting that
should bring the side-to-side level back to normal.
Adjusting Front-to-Rear Pitch
The blade should be 1/8-1/4 inch (3.1-6.3mm) lower in
front than in the rear. If it is not within specification,
adjust the rear link.
Turn the locknut on the link (Figure 61).To raise the
front of the mower, turn the locknut clockwise. To lower,
turn the locknut counterclockwise.
