STEP 3: Move Tiller Off Shipping
Platform
To move the tiller without the engine
running, put the wheels in their
FREEWHEEL position, as described below.
1. Use a sturdy block to raise one wheel
off the ground.
2. Remove the hairpin cotter (L, Fig. 2-3)
and wheel drive pin (M). Slide the wheel
inward on the wheel shaft (N). Reinstall
the wheel drive pin and hairpin cotter
through the wheel shaft only (not through
the wheel hub). Repeat with the other
wheel.
3. Using the handlebar as a lever, roll the
tiller to a flat area.
IMPORTANT: Before starting the engine,
the wheels must be placed in their WHEEL
DRIVE position (pins through wheel hubs
and wheel shaft). This procedure is
described in “Wheel Drive Pins” in
