Service And Adjustments; Storage - Craftsman 486.244412 Operator's Manual

42" snow blade
Hide thumbs


To Adjust Blade Spring
The tension of the blade adjust spring may be altered
to permit the blade to tilt forward to bypass solid
obstructions. To change the spring tension, adjust the
nuts at upper end of the spring bolt. Standing in front
of blade, turn the nuts counterclockwise to relieve
tension and clockwise to increase tension. Refer to
figure 21 on page 11.
To Adjust Blade Shoes
The blade shoes at the ends of blade may be raised
for close work on smooth surfaces or lowered to raise
the blade to work on rough or uneven areas. Make
sure both shoes are set evenly and that the nuts are
tightened securely.
Recommendations When Storing
When the snow blade is not being used, remove all
dirt and rust and touch up with paint.
Touch up bare metal with paint or apply a light coat of
grease or rust preventive.
Lubricate all pivot points and all points shown in
figure 29, page 15 in the maintenance section.
Store in a dry area, protected from weather.
To Remove Blade From Tractor
Lower the blade to the ground with the blade in the
center (straight ahead) position.
Remove the hairpin cotter which fastens the blade
pivot rod to the blade pivot shaft. See figure 26 on
page 13.



To Adjust the Blade Pivot Lock Mechanism
If the blade will not unlock and pivot, the angle lock
bars are not disengaging from the slots in the pivot
plate. To correct, adjust the 5/16" hex jam nuts to
draw the end of the control cable back towards the
cable mount bracket. The less the threaded end of
the cable extends through the bracket, the more the
angle lock bars can retract to disengage from the
slots in the pivot plate.
5/16" HEX
Remove the hairpin cotter which fastens the lift
handle rod to the lift link pin. See figure 23, page 12.
Remove the hairpin cotter from the channel pivot pin
and remove the pivot pin from the channel assembly.
See figure 22 on page 12.
Remove the blade, the channel assembly and the
lift handle assembly from the tractor. The brackets
assembled to the tractor frame may be left in place.
To remove the brackets assembled to the tractor
frame (side plates and pivot support brackets) refer
to the figures appropriate for your tractor on pages 6
and 7.
If the side plates are removed from the tractor frame,
be sure to reassemble any bolts that were removed
from the frame. Refer to figure 5 on page 6 and figure
7 on page 7.
