The warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
The left and right side of the machine is determined
by sitting on the seat in the normal operator’s
position.

The attachment lift lever (Fig. 17) is used to raise and
lower various attachments.
Raising Attachments
1. Depress the clutch and/or brake pedal(s) to stop
the machine.
2. Pull attachment lift lever rearward until latch
locks. In this position the lift will hold the
attachment in the up, or raised position.
Lowering Attachments

the machine.
2. Pull attachment lift lever rearward, to release lift
pressure, and push the button on top to release
the latch. Move lift lever forward to lower
attachment.
Adjusting Dial-A-Height
The Dial-A-Height control (Fig. 17) is used to limit
the downward travel of the attachment. The
Dial-A-Height knob is rotated to change the location
of this stop, up or down.
1. Raise the attachment lift lever: Refer to Raising
Attachments. In the raised position the
Dial-A-Height knob (Fig. 17) can be rotated to
change the stop location. Turn clockwise to raise
and counterclockwise to lower the height of the
attachment.
2. The Dial-A-Height indicator (Fig. 17) will show
the change, high to low, in attachment lift height
as adjustment is made.

Tips for Using Snow Blade
Remove snow as soon as possible after it falls. This
produces best snow removal results.
Snow is generally removed from driveway by making
one pass down the center and then plowing snow to
either side on successive passes.
If tractor looses traction when using snow blade,
wheel weights and tire chains may be available from
your dealer.
Blade trip springs can be adjusted for scraping
aggressiveness and surface conditions. Second hole
from the top is recommended for snow. Refer to
adjusting blade trip springs.

Maintenance
Reversing the Scraper Blade
The scraper blade contacts the ground preventing
damage to the snow blade. Periodically inspect the
scraper blade for wear. When scraper becomes worn,
before working surface contacts the housing, reverse
the scraper blade.

parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2. Raise the attachment lift lever: Refer to Raising
Attachments, and support the housing off the
ground.
3. Remove lock nuts and carriage bolts to remove
scraper blade (Fig. 21).
4. Reverse scraper blade to replace a worn edge and
install with previously removed hardware
(Fig. 21).
Storage
1. Before long term storage wash the machine with
mild detergent and water to remove dirt and
grime from the entire machine.
2. Check the condition of the scraper blade; refer to
Reversing Scraper Blade, page 16.
3. Grease and oil the blade; refer to Greasing and
Lubrication, page 15.
4. Check and tighten all bolts, nuts, and screws.
Repair or replace any part that is damaged or
defective.
5. Paint all scratched or bare metal surfaces. Paint
is available from your Authorized Service
