Troy-Bilt 8 HP - Manual (Page 25)

OPERATION OF TILLER
When the tiller is operating in
“REVERSE”, the wheels and tines
are powered by the rubber reverse
disc and not the belt. Therefore,
you have only two reverse speeds
as determined by the “SLOW” and
“FAST” positions of the Wheel
Speed Lever.
IMPORTANT
Proper belt tension is critical to
good performance. Check the ten­
sion after the first 2 hours of new
operation and every 10 hours
thereafter. See "Drive Belt Mainte­
nance" in Section 6.
To change from “LOW” range to “HIGH” range:

WARNING
To help avoid personal injury, stop
the engine, remove the electric start
key, disconnect the spark plug
wire, and let the engine and muffler
cool before changing belt speeds.
1. Place the Wheels/Tines/PTO
Drive Lever in “NEUTRAL”.
2. While kneeling on the left side
of the tiller, create slack in the belt
by reaching over to the right side
of the pulleys and pushing in on
the center of the belt with your
finger. Then use your left hand to
work the belt part way into the
forward groove of the transmission
(lower) pulley. See Photo 3-15.
Now go to the other side of the
tiller and finish seating the belt In
the groove.
3. On the left side of the tiller, work
the belt part way into the forward
groove of the engine (upper) pul­
ley. See Photo 3-16. Then go to the
other side and finish seating the
belt. NOTE: If additional clearance
is needed to fit the belt over the
engine pulley, simply raise the
Wheels/Tines/PTO Drive Lever into
the “REVERSE” position. This will
lower the engine pulley.
