INTRODUCTION
This Section describes the location and
function of the controls on your tiller.
Refer to the following Section, Operation
for detailed operating instructions.
Practice using these controls, with the
engine shut off, until you understand the
operation of the controls and feel confi-
dent with each of them.
ENGINE CONTROLS
Refer to the engine manufacturer’s Engine
Owner’s Manual (included in the tiller liter-
ature package) to identify the controls on
your engine.
IMPORTANT: The control for stopping the
engine is located on the engine.
WHEEL DRIVE PINS
Each wheel is equipped with a wheel drive
pin (A, Figures 3-2 and 3-3) that secures
the wheel to the wheel shaft (B). The
wheels can be positioned in either a
WHEEL DRIVE or a FREEWHEEL mode.
Before starting the engine, put both
wheels in the WHEEL DRIVE position by
inserting the wheel drive pins through the
wheel hubs and the wheel shaft. Doing so
“locks” the wheels to the wheel shaft,
causing the wheels to turn when either the
Forward Clutch Bail (all models) or the
Reverse Clutch Control (Models 634F and
634B) is engaged.
Use the FREEWHEEL mode only when the
engine is not running. In FREEWHEEL, the
wheel drive pins are placed only through
the holes in the wheel shaft (not the wheel
hubs), thus allowing the wheels to turn
freely when you manually move the tiller.
To place the wheels in WHEEL DRIVE or
FREEWHEEL:
1. Stop engine, disconnect spark plug wire
from spark plug and allow engine to cool.
2. Raise one wheel about one inch off the
ground and place a sturdy support under
the transmission.
3. Remove hairpin cotter (C, Figures 3-2
and 3-3) from wheel drive pin (A).
4. FOR WHEEL DRIVE MODE (Figure 3-2):
Slide wheel outward and align holes in
wheel hub (D, Figure 3-2) and wheel shaft
(B). Insert wheel drive pin (A) through
wheel hub (D) and wheel shaft (B). Secure
wheel drive pin with hairpin cotter (C) by
pushing hairpin cotter in as far as it will
go. Repeat with the other wheel and then
remove the support from beneath the
transmission.
5. FOR FREEWHEEL MODE (Figure 3-3):
Slide the wheel inward and insert the
wheel drive pin (A, Figure 3-3) only
through the hole in the wheel shaft (B).
Secure wheel drive pin with hairpin cotter
(C) by pushing hairpin cotter in as far as it
will go. Repeat for the other wheel and
then remove the support from beneath the
transmission.
Before operating your machine, care-
fully read and understand all safety,
controls and operating instructions in
this Manual, the separate Engine
Owner’s Manual, and on the decals on
the machine.
Failure to follow these instructions can
result in serious personal injury.
WARNING
Never allow either of the wheels to be
in the FREEWHEEL position when the
engine is running. Always put both
wheels in the WHEEL DRIVE position
before starting the engine.
Failure to comply could cause loss of
tiller control, property damage, or per-
sonal injury.
WARNING
Figure 3-1: Tiller features and controls (5.5HP Model shown). See separate Engine Owner’s
Manual to identify engine controls.
