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
• Speed ranges
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.
Before starting engine: disengage PTO and set parking
brake.
Start and operate unit only when seated in operator’s
position. Steering control levers must be in neutral, PTO
disengaged and parking brake set when starting engine.
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.
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.
GB - 6
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.
Operate up and down slopes, not across slopes. DO
NOT operate on slopes of more than 17˚. Keep all
movement on slopes slow and gradual. DO NOT make
sudden changes in speed or direction. Use a slow speed
to avoid stops or shifts on slopes. Avoid starting or
stopping on a slope. Use of a Roll Over Protection
System (ROPS) is recommended for slope operation.
Use slow speed on any slope. Choose a low gear so that
you will not have to stop or shift while on the slope.
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.

3. With the unit up to and facing a wall, jack the unit up
so that both drive wheels are off the ground.
4. Have someone depress center of seat to actuate
seat switch.
5. Start the engine and run at about half throttle or
faster. Release parking brake.
6. Move the control levers from Forward to Reverse
several times to make sure controls are free and
check Neutral adjustment. If binding is found,
correct it.
7. Minor adjustments may be made by simply adjusting
the stop screw which contacts the lever on the pump.
The screw may be turned in or out to bring the unit
into neutral.
8. If major adjustment is needed, it is best to remove
the front ball joint from the bottom of the control
levers and turn the stop screw in or out until neutral is
found.
9. Then, with the adjustable arms of the parking brake
set so the clamping bolt is in the middle of the slot,
adjust the ball joint on or off the control link rod so
that their mounting bolts fit into the slot at the end of
the adjustable interlock.
10.Reinstall the front ball joint(s).
NOTE: When properly adjusted, the parking brake interlock will move upward when the parking brake is set and
hold the steering control levers in neutral. The parking
brake starting interlock switch will not be depressed
unless the steering control levers are in neutral. The
interlock holds the levers in neutral until the parking brake
is released.
11. Move the control levers, from forward to reverse
several times to make sure it is adjusted to neutral.
Readjust if necessary.
12. Stop the engine.
Adjusting Control Levers
To be done after neutral has been set. (Figure 13)
1. If desired the steering control levers can be set to
match (be in line) when in neutral.
2. Remove front ball joint from bottom of steering
control lever on side which is going to be adjusted.
Screw ball joint on or off link rod to hydrostat so that
control levers align. Replace rod end on lower part of
steering control lever.
3. If needed adjust parking brake interlock so that
interlock is able to move up when both steering
control levers are in neutral. To do this loosen the
clamping bolt on the adjustable member of the
interlock and slide it in either direction until the
interlock moves up and latches the ball joint
mounting bolts.
1. If hydraulic system is cold, run unit for a minimum of
five minutes, then shut off unit.
2. Make sure both control levers are in neutral.
GB - 17
Adjusting the Parking Brake
1. The Parking Brake may be adjusted through the use
of the jam nuts on the brake rod which push against
the compression spring which pushes on the caliper
arm.
2. Turn the nuts further on the rod (clockwise) to tighten
the brake and further off the rod (counter clockwise)
to loosen the brake.
3. Ensure when the brake is applied, the caliper arm
does not contact the return nuts on the rod in front of
the caliper arm. If they do, back them off slightly.
4. When installing new pads in the calipers, they must
be burnished by driving for a short distance (about
200 feet) with the brake on. To do this, bring the
parking brake lever part-way up while driving
normally (in a straight line). This quickly breaks-in the
pads for maximum effectiveness.
Adjusting the unit to Track Straight
Check and adjust tire pressure. Increase pressure on
side unit tracks to. DO NOT exceed maximum
recommended tire pressure (refer to Specifications).
If tire pressure adjustment does not solve tracking
problem, the limiter bolts at base of handles can be
adjusted. Front bolts are for forward and rear bolts are for
reverse. Lengthen bolts (move closer to lever) on side
which is too fast.
Adjusting Anti-Scalp Rollers
The anti-scalp rollers are set at the factory for typical
mowing height, but can be adjusted for high or low cutting
conditions.
Rollers are intended to prevent lawn scalping, not to
control cutting height.
For a very high cutting height, set the rollers in their
lowest position on the bracket.
For a very low cutting height, set the rollers in their
highest position on the bracket.
All rollers should be set at the same height.
The mower is leveled from side to side with the slots
where 4 chains fasten to the mower mounting brackets.
The mower is leveled from front to rear by adjusting the
rod running down each side of the frame (Figure 15).
1. Raise mower deck and insert 3" (7.6 cm) tall blocks
to support deck.
2. Lower deck onto blocks so chains are slack.
3. Measure from bottom of mower blade end to ground.
4. Set hydraulic lift cylinder so cut of height reads the
same as blade height measurement.
5. Loosen the locknuts on the side where the chains are
slack and slide the bolt down the slot until the chain is
tight.
6. Tighten bolt and nuts in mower mounting brackets.
7. Lift mower and remove blocks.
8. Measure height of deck at each side. Measurements
must be within 1/16" (1.5 mm) of each other.
9. If measurements are out of range, fix by adjusting
chains on low side of deck.
10.Once deck is level side to side, measure height of
deck at middle of front and on both sides of rear.
Front of deck should be 1/8" (3 mm) lower than rear.
11.To adjust, loosen rear hex nut of the front mower lift
pivot on each rod.
12.Turn the front hex nut on each rod until mower is 1/8"
(3 mm) lower in front.
NOTE: If mower cannot be leveled it may be necessary
to loosen the rear nut of the rear mower lift pivot to get
more threads at the front of rod for adjustment. After loosening rear nut and adjusting level, tighten front nut on
rear mower lift pivot.
13.Tighten rear hex nut on each rod that was loosened
in step 11.

reasonable, and usual personal, family, or household uses. If the product is put to any
business, commercial, or industrial use, such as, but not limited to, commercial

after the date of purchase, or one (1) year after the date of purchase for the Pro 21

(90) days after date of purchase.
Genuine Gravely service parts and accessories not purchased with the product
covered by this warranty, but which are later purchased and used with that product,
are warranted to be free from defects in material and workmanship for a period of
ninety (90) days after date of purchase, and Gravely will repair or replace any such

The following items are not covered by this warranty:
• Engines and engine accessories are covered only by the
warranty made by the engine manufacturer, and are not
covered by this warranty.
• If the product is equipped with a Peerless gearbox and/or
transmission, the gearbox and/or transmission are covered
only by the warranty made by Peerless, and are not covered
by this warranty.

LIMITATION OF REMEDY AND DAMAGES
Gravely’s liability under this express warranty, and under any
implied warranty that may exist, is limited to repair or replacement
of any defective part. Gravely shall not be liable for incidental,
special, or consequential damages (including lost profits). Some
states do not allow the exclusion of incidental or consequential
damages, so the above limitation or exclusion may not apply
to you.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
DISCLAIMER OF FURTHER WARRANTY
Gravely makes no warranty, express or implied,
other than what is expressly made in this
warranty. If the law of your state provides that
an implied warranty of merchantability, or an
implied warranty of fitness for particular purpose,
or any other implied warranty, applies to Gravely,
then any such implied warranty is limited to the
duration of this warranty. Some states do not
allow limitations on how long an implied warranty
lasts, so the above limitation may not apply to
you.
