42” Snow Plow/Dozer Blade
Normal Care
After dozing jobs, hose down the blade to remove
excess dirt. Coat bare metal surfaces to prevent rust-
ing. Lightly oil all pivot points.
If the wear plate (A, figure 9) on the bottom of the 42”
blade is worn excessively, replace it
wrth
a new one
by removing the six carriage bolts (B), lo&washers
(C) and nuts (D).
ADJUSTMENTS
Lift Rod
For initial setting, place front set collar (A, figure 10)
1”
from rod guide with blade fully lowered. Place rear
set collar (B) against spring (C). Tighten the
setscrews in the two set collars. To adjust, perform
the following:
1. Fully raise the blade by raising on the tractor lift
lever. Measure distance between scraper bar and
ground. If it measures approximately
6”,
it is prop
erly adjusted. If not, proceed to step 2.
2. Lower the blade. Loosen the setscrew in the front
set collar. Move the set collar back to increase
clearance or forward to decrease clearance.
Tighten the setscrew. Recheck the measurement.
MOTE:
D%rent
ground contours may require differ-
ent adjustments. Lower the blade to adjust rear set
collar. Moving the rear set collar toward rear will allow
the blade to follow a rolling contour. The farther back
the rear set collar is positioned, the more the blade
will float. Moving the rear set collar toward the front
will increase blade down pressure.
