Snowblowing Tips
Operate engine at full throttle.
Operate tractor at a safe travel speed.
Slow down when you operate on slopes, before you make a turn, and when you operate close to buildings or trees.
For snowblowing in drifts, drift blade will cut through drifted snow and help break down drifts.
Blow snow downwind, if possible.
Put hydraulic control lever forward to float position when you are snowblowing on irregular ground.
Adjust runners for proper scraper blade clearance before you remove snow from irregular ground.
Travel slow when blowing wet, heavy snow to prevent plugging.
Clean snowblower after each use.
Look carefully behind tractor before you back up, especially for children.
Raise snowblower when driving between jobs.
Do not try to clear snow from a steep slope.
Do not operate near edge of a ditch, or bank. Keep away from drop-offs, holes, rocks, and roots. Watch for hidden hazards.
