Blade angle lock bars:
Blade angle can be adjusted at the blade pivot
in front of tractor by first raising the blade to
transport position, pull back on angle lock bars
to release the blade and pivot to the right,
center', or left positions_ Release lock bars to
lock.
To adjust blade angle from the tractor seat:
Raise blade to transport position, shift tractor

angle lock bars. Move tractor forward slowly,
dragging the right, or left end of blade against
snow bank (or other' object) to angle blade to
right or left. Release rope to lock.
Adjust blade spring:
Blade adjust spring tension is adjustable to
permit blade to tilt forward to by pass solid
obstructions.
KNOW THE TERRAIN. AVOID EXCEP-
TIONALLY'SHARP SLOPES OR DROP-
OFFS WHICH MAY BE HIDDEN BY
THE SNOW.
NEVER RUN THE SNOW BLADE
INTO HEAVY MATERIAL AT HIGH
SPEED.
C, Blade shoe adjustment:
Blade shoes on ends of blade, (see figure 18),
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 nuts are tightened securely.
NOTE
Wheel weights and tire chains should
