Checking and Adjusting the Blade Level

Adjusting Blade Tracking

On mowers with multiple blades, not only do the blades
need to be a minimum of 1/8 inch up from the bottom
edge of the housing, but they must also line up where
the tips come together. Take the two blade tips and
point them towards each other. They must be within
1/8-3/16 inch of level with each other, or both must be
the same distance from the blade to the ground
(Figure 62).

Another method is to remove the blades and place a
straight edge between the blade saddles (Figure 63).
They should be in line. If they are not, loosen the bolts
securing the spindle housing to the mower housing.
Insert shim washers and recheck. Once you have the
alignment, remove the bolt and reinstall through the
spindle housing, washer, and mower housing to secure
the shim.
Figure 63
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
4 - 20
washers to shim the spindle housing, remove the bolt
and reassemble through the washer to secure it.

Adjusting Side-to-Side Level

All mower attachments for the 5xi series tractors
should be level side-to-side within about 3/16 inch
(4.76mm). However the adjustment point for the
60-inch (152.4cm) mower is different than the other
models.

44-, 48-, 52-inch (111.7, 121.9, 132.0cm) Mowers

Equalize side-to-side cut by adjusting the two carriage
bolts on the gage wheel shaft on the back of the mower
(Figure 65).
