StartingtheEngine
NOTE:
Refer to the TRACTOR SET-UPon page 9 of this
manual for Gasoline and Oil fill-up instructions.
Insert the tractor key into the ignition switch.
Place the PTO knob in the disengaged (OFF)
position.
Engage the tractor's parking brake.
Release both control handles.
Move the throttle control lever into the FAST (or
CHOKE, if so equipped) position.
Pull out the choke control knob, if so equipped (a
warm engine may not require choking).
Turn the ignition key clockwise to the START
position. After the engine starts, release the key. It
will return to the ON position.
IMPORTANT: Do NOT hold the key in the START
position for longer than ten seconds at a time. Doing so
may cause damage to your engine's electric starter.
NOTE:
Both control handles must be in the Neutral
(STOP) position when starting or the engine will NOT
crank.
As the engine warms up, gradually push the choke
control knob inward (or move the throttle control lever
out of the CHOKE position into the FAST position) to
open up the choke plate on the engine's carburetor.
NOTE:
Do NOT leave the choke control out while
operating the tractor. Doing so will result in a "rich" fuel
mixture and cause the engine to run poorly.
Stopping the Engine

If you strike a foreign object,
stop the engine, disconnect
the spark plug
wire(s)
and
ground

damage. Repair the damage before starting
and operating.
If the blades are engaged, place the PTO knob in
the disengaged (OFF) position.
Turn the ignition key counterclockwise
to the OFF
position.
Remove the key from the ignition switch to prevent
unintended starting.

Drivingthe Tractor
WARNING:

before and while backing up to avoid a back-
over accident.

any other separately available rear attachment is not
being used, make certain that the rear weight is
propedy secured before operating the tractor.
The Revolution
TM
lawn tractor is operated in the same
manner as a conventional dding mower with the
exception of control handles used in place of a steering
wheel allowing for greater maneuverability.
The rear tires of the Revolution TMboth propel the lawn
tractor as well as steer it. This allows the tractors front-
end to pivot freely on castor wheels.
ControlHandles
The right control handle controls the right rear wheel.
The left control handle controls the left rear wheel.
The further forward a control handle is positioned,
the faster the wheel it controls will drive forward.
The further rearward a control handle is positioned,
the faster the wheel it controls will drive in reverse.
Moving each control handle in varying positions allows
the operator to maneuver the tractor in neady any
direction. Refer to the chart on the following page for a
quick reference of basic control handle positions and
their relation to the direction the tractor will travel.

DrivingTips
First-time operators should start off in an open area
with bystanders at a significant distance away.
Position the adjustable hand rest in the slowest
(nearest the operator) position while learning how
to drive the tractor.
Position the throttle lever at a low RPM (near the
Turtle) and practice maneuvedng the tractor with
the PTO always in the disengaged (OFF) position.
Practice maneuvering the tractor around moveable
objects such as pylons or cardboard boxes (NOT
trees) to help get comfortable with the controls.
Gradually increase throttle speed and become
completely
comfortable with the tractor's controls
before placing the PTO knob in the engaged (ON)
position and using the tractor to cut grass.
