LIFT ROD ADJUSTMENT
WARNING
On tractors with hydraulic lift levers it will be
necessary to start the engine to raise or lower the lift
lever. Always seat yourself in operator’s position
before starting engine. Always shut off engine and
remove key before leaving seat. Make sure parking
brake is set and moving parts have stopped.
1. Fully raise the snowthrower. Measure the clearance
between the scraper bar and the ground. The
clearance should be about 3-1 /2 to4 inches(89 to 102
mm). If not, perform step 2. If clearance is correct, go
to step 3.
2. Lower the snowthrower. Loosen the setscrew ion the
front set collar (A, figure 17). To increase clearance,
move the set collar toward the rod guide (B). To
decrease clearance, move the set collar away from
rod guide (toward front). Tighten the setscrew. Raise
the snowthrower and recheck the measurement.
Readjust if necessary'.
3. The scraper blade will float over the surface bumps
or dig into them depending on the down pressure.
The initial adjustment made during snowthrower
installation may be suitable. If not, fully raise the
snowthrower. Loosen the setscrew in the rear set
collar (D). To allow scraper blade to float more,
move the rear set collar toward the rear. To increase
down pressure, move the rear set collar toward the
spring (C). Tighten the setscrew. Lower the lift lever.
A WARNING
On tractors with hydraulic lift levers, keep hands
and feet from under snowthrower when snow¬
thrower is in raised position. Snowthrower may
lower when engine is off.
