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.

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. 16).
4. Reverse scraper blade to replace a worn edge and
install with previously removed hardware
(Fig. 16).
Storage
1. Before long term storage wash the blade with
mild detergent and water to remove dirt and
grime from the entire attachment.
2. Check the condition of the scraper blade; refer to
Reversing Scraper Blade, page 13.
3. Grease and oil the blade; refer to Greasing and
Lubrication, page 12.
4. Check and tighten all bolts, nuts, and screws.
Repair or replace any part that is damaged or
defective.
