ADJUSTING LIFT HEIGHT, LEVELING

The snow thrower is equipped with two threaded lift

linksforadjustingtheliftheightandlevelingofthesnow

thrower in the raised position.

Themaximumliftheightisapproximately4inchesground

clearance for GT tractors and 3 inches for YT tractors.

TO ADJUST THE LIFT HEIGHT:

• Raisethesnowthrowertothehighestposition.

• Checktheclearancebetweentherearoftheidler

bracketandtheliftshaft.Aminimum1/16"clearance

intheraisedpositionisnecessarytoavoidpossible

• Toincreasetheliftheight,tightenthenutsonthe

bottomofbothliftlinksequallyuntilthemaximumlift

heightisobtained.

TO LEVEL WHEN RAISED:

• Ifthesnowthrowerisnotlevelintheraisedposition,

loosenthenutatthebottomoftheliftlinkonthehigh
