SAFETY RULES
Operation
Read, understand, and follow all instructions in the
manual and on the machine before starting:
• How to operate all controls
• The functions of all controls
• How to stop in an emergency
• Braking and steering characteristics
• Turning radius and clearances
ALWAYS keep protective structures, guards, and
panels in good repair, in place and securely fastened.
Complete a walk-around inspection of the unit and
work area.
ALWAYS disengage PTO, stop unit and engine, remove
key, engage parking brake and allow moving parts to
stop before leaving operator’s position.
ALWAYS remove key to prevent unauthorized use.
Check for weak spots on dock, ramps or floors. Avoid
uneven work areas and rough terrain.
Dust, smoke, fog, etc. can reduce vision and cause an
accident. Mow only in daylight or good artificial light.
Watch for traffic when operating near or crossing
roadways.
7
Only allow responsible adults who are trained and
familiar with the instructions to operate the machine.
Training includes actual operation.
Clear the area of objects such as tree branches, rocks,
toys, wire, etc., which could be picked up and thrown by
the blades. Tall grass can hide obstacles.
Be sure the area is clear of people before mowing.
Stop machine if anyone enters the area.
Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.
Watch for holes, ruts, or bumps. Uneven terrain could
overturn the machine.
Do not mow in reverse unless absolutely necessary.
Always look down and behind before and while
backing.
Be aware of the mower discharge direction and do not
point it at anyone. Always stand clear of discharge
area.
DO NOT operate at too fast a rate.
DO NOT change engine governor settings or
over-speed engine. Slow down before turning.
Disengage PTO when attachment is not in use.
ALWAYS turn off power to attachment when
transporting, crossing driveways, etc.
Stop engine before removing grass catcher or
unclogging chute.
Do not operate mower unless bagger is attached or
guards are in operating position.
If you cannot back up a slope or you feel uneasy on it,
do not mow it.
Mow up and down slopes, not across them.
Use slow speed on any slope. Choose a low gear so
that you will not have to stop or shift while on the slope.
Follow the manufacturer’s recommendations for wheel
weights or counterweights to improve stability.
Use extra care with grass catchers or other
attachments. These can change the stability of the
machine. Use only approved hitch points.
Keep all movements on the slope slow and gradual . Do
not make sudden changes in speed or direction.
Avoid starting or stopping on the slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope.
Do not mow near dropoffs, ditches, or embankments.
The mower could suddenly turn over if a wheel is over
the edge of a cliff or ditch, or if an edge caves in.
Do not mow on wet grass. Reduced traction could
cause sliding.
Do not try to stabilize the machine by putting your foot
on the ground.
Do not use grass catcher on steep slopes.
Do not operate on slopes over 10˚ maximum.
Do not park on slopes unless necessary. When parking
on slope always chock or block wheels. Always set
parking brake.
Know the weight of loads. Limit loads to those you can
safely control and the unit can safely handle.
Use only attachments or accessories designed for your
unit.
Check attachment components frequently. If worn or
damaged, replace with manufacturer’s recommended
parts.
Personal

Always wear safety glasses or eye shields while
operating your tractor or performing any adjustments or
repairs. We recommend a wide vision safety mask over
eye glasses, or standard safety glasses.

Shut off engine, remove key, read manual before you
unplug, adjust or repair unit.
DO NOT run engine in an enclosed area. Always
provide good ventilation. Fumes from engine exhaust
can cause injury or death.

involved in a larger percentage of riding mower related
injuries. These operators should evaluate their ability to
operate the riding mower safely enough to protect
themselves and others from serious injury.

OPERATION
CONTROLS AND FEATURES
CAUTION: The operation of any tractor can
result in foreign objects thrown into the eyes,
which can cause severe eye damage. Always
wear safety glasses or eye shields while
operating your tractor or performing any
adjustments or repairs. We recommend a
wide vision safety mask over eye glasses, or
standard safety glasses.
Operator Presence System
Your tractor is equipped with an operator presence
switch. When engine is running, any attempt by the
operator to leave the seat, without first disengaging
attachment and placing the Steering Control Levers in
neutral, will shut off the engine.
The engine must shut off if the operator leaves the seat
while the Travel-Speed Control Levers are in any
position other than the "NEUTRAL LOCK" position, or
while the PTO Switch is in the "ON" position.
Do not operate tractor unless operator presence
system functions as described. Contact your Gravely
Dealer for repair.
Ignition Switch
The ignition switch is operated with a
removable key. To start the unit, the
switch is turned clockwise from the
"OFF" position to the "START"
position. The key will spring back to
the "RUN" position.
"OFF" Position: Ignition system is shut down.
"RUN" Position: All controls are operable.
"START" Position: Starter turns over the engine.
To stop the engine, turn the key to the "OFF" position.

Throttle Control (2048 only)
Always operate engine at full throttle.
Moving the lever to the "FAST" position
increases the engine speed.
Moving the lever to the "SLOW" position
decreases the engine speed.
• Operating engine at less than full
throttle reduces the battery charging
rate.
• Full throttle offers the best bagging
and mower performance.
FAST
SLOW
Throttle / Choke Control (1742 only)
Always operate engine at full throttle.
Place the lever in the "Choke" position to
start a cold engine.
Move the lever to the "FAST" position to
increase the engine speed.
Move the lever to the "SLOW" position to
decrease the engine speed.
• Operating engine at less than full
throttle reduces the battery charging
rate.
• Full throttle offers the best bagging
and mower performance.
FAST
SLOW
Power Take-Off (PTO) Switch
The Power Take Off Switch is used to engage and
disengage the attachment.
When the PTO Switch is pulled out, it is in
the "ON" position and the attachment is
engaged.
When the PTO Switch is pushed in, it is in
the "OFF" position and the attachment is
disengaged.
OE0340
OE0340
OE0261
Choke Control (2048 only)
When starting a cold engine:
Pull the choke control out to engage choke.
Push the choke control in after engine has warmed up
for about 10 seconds.
Parking Brake
To engage the Parking Brake, lift up on lever.
To disengage the Parking Brake, push lever down.
If one or both of the wheels do not turn easily, check
the brake to assure it is disengaged.
Parking Brake Interlock
Engine will shut off if control levers are taken out of
neutral lock with brake engaged.
Travel/Speed Control Levers
WARNING: This tractor is steered and
stopped through the rear drive tires which are
controlled by the Steering Control Levers. Any
loss of tire traction will also result in loss of
braking and steering control. Care must be
exercised not to use unit on a slope greater
than recommended. Loss of tire traction, and
loss of steering and brake control could result,
leading to serious injury.
