Hazard control and accident prevention are dependent
upon awareness, concern, prudence, and proper training
involved in operation, transport, maintenance, and
storage of the riding mower. Therefore, it is absolutely
essential that no one operates the mower without first
having read, fully understood, and become totally familiar
with the Operator’s Manual. Make sure the operator has
paid particular attention to:
Refer to Figure 2-2:
A cable is linked from engine to throttle for controlling
engine speed. Move throttle lever toward fast position to
increase engine rpm and toward slow position to
decrease rpm. Always travel and cut grass with throttle
set at full engine rpm speed. Decrease travel speed by
pulling back on the control levers. Reduce engine rpm
only when mower is not traveling and just before
engaging the cutting blades.

DANGER
Never make sudden stops or sudden reversing of travel
direction, especially when going down a slope. The steering is
designed for sensitive response. Rapid movement of control
levers could result in a reaction that can cause serious injury.
!
DANGER
Never make sudden speed changes from reverse to forward.
Always push control levers forward gently to avoid sudden
change in speed. Any sudden forward speed change can cause
the front wheels to raise off the ground resulting in loss of
control, mower damage and/or personal injury.
NOTE: When turning on soft wet turf, keep both
wheels rolling either forward or backward. Pivoting
on a stopped wheel can damage the turf.
To Start and Increase Speed
Refer to Figure 2-8 on page 17:
After starting the engine, release park brake and engage
control levers by moving handles fully (IN). This makes
the levers ready for steering while traveling.

installed and in good condition at all times during operation.
!
DANGER
Never place hands or feet under the deck or attempt to make
any adjustments to the mower deck while the engine is running
or when blades are engaged. Mower blades rotating at a high
speed cannot be seen and are located very close to the deck
housing. Fingers and toes can be cut off instantly.
!
DANGER
Do not mow with people present in the mowing area.
Projectiles can suddenly, without warning, discharge from
under the mower deck causing serious injury or death.
!
DANGER
Never direct discharge of material from mower deck towards
people, animals or buildings. Keep discharge chute in its
lowest position and never remove discharge chute unless a
complete grass collection system is in place. Projectiles can
suddenly, without warning, discharge from under the mower
deck causing serious injury or death.
!
WARNING
!
CAUTION
The tailpipe and muffler are very hot and can ignite dry
grasses, brush and other flammable materials. Always keep
area around muffler and tailpipe clear of debris. Allow muffler
and tail pipe to cool completely before removing any debris to
prevent sever burns to the body. Make sure all debris around
the muffler have been removed before parking mower inside a

brush from collecting on and around engine and
muffler parts.
 Use extreme caution when cresting hills or when
visibility is limited. Proceed slowly until you are sure
conditions immediately ahead are safe.
 Do not operate mower at night. With poor visibility,
night operation can lead to a serious accident.
 Do not operate mower on streets, highways, public
roads, or where it may be a hazard to faster moving
traffic.
 Do not leave mower unattended with engine running.
 Always park on level ground with control levers fully
apart in neutral, park brake set, engine shut off, and
switch key removed before leaving mower unattended.
 Do not touch engine, engine exhaust pipe and/or
muffler while they are hot.
 Always disconnect negative battery terminal before

 Do not tow mower with its wheels on the ground.
3/16/17
Always tow mower loaded on a trailer. Make certain
the mower is properly secured to the trailer and its
park brake is locked.
 Do not smoke or use electrical devices including cell
phones while refueling.
 When refueling use a UL listed container that has a
screen or filter. Set container on the ground before
fueling to eliminate static discharge. Do not use
Methanol fuel.
 Support this mower securely before working beneath.
Chock wheels to prevent mower from rolling.
 Always check wheel lug nut torque values two hours
after initial operation and two hours after each tire
repair and/or replacement. Routinely check lug nut
torque valves every 50 hours of operation. See also
“Torque Requirements” on page 29.
Engage blades with engine running at medium
speed. Pull up on blade engagement switch to start
blades turning. (Refer to Figure 2-2 on page 12). Once
blades are fully engaged and turning, increase engine
speed to maximum engine operating speed.
NOTE: Engaging blades when under heavy load
(i.e. tall grass) or at high engine rpm can cause
premature belt wear and/or belt damage.
Cut grass with blades operating at full speed. Your
Zero Turn Mower operates at peak mowing performance
and gives the best cut when the throttle is set at full RPM.
This gives maximum power to the drive wheels and
cutting blades when needed. Use control levers to control
ground speed rather than engine RPM.
The mower’s control levers are very responsive. For
smooth operation, move levers slowly, avoid sudden
movement. Skill and ease of operation come with
practice and experience. Inexperienced operators may
have a tendency to over-steer and lose control.
Slow-moving practice maneuvers are recommended to
become familiar with these characteristics before
attempting normal speed operation.
Sharp depressions or raised obstacles (such as gutters
or curbs) should not be directly approached at high
speed in an attempt to jump them as the operator could
be thrown from the mower. Approach at a slow speed and
angle one drive wheel at the obstruction. Continue at an
angle until both wheels clear the obstruction.
When turning on soft wet turf, keep both wheels rolling
either forward or backward. Pivoting on a stopped wheel
can damage the turf.
Select a mowing pattern that discharges cut grass
away from uncut grass. Use a pattern utilizing left turns
because cut grass is discharged to the right. Avoid
discharging cut grass onto uncut areas as grass is then
mowed twice. Mowing twice puts an unnecessary load
on the mower and reduces mowing efficiency.

Keep blades sharp. Many problems with incorrect
cutting patterns are due to dull blades or blades which
have been sharpened incorrectly. Information on
sharpening blades is listed in this manual’s maintenance
section. In addition, most communities have individuals
or companies which specialize in sharpening mower
blades. Blade sharpness should be checked daily.
General Operating Information
After thoroughly familiarizing yourself with the Operator’s
Manual and completing the Operator’s Checklist, you are
almost ready to begin mowing.
Approach the mower from the front and spread the
steering levers fully apart. Stand just to the outside rear
of the left front anti-scalp wheel and with your right hand
grab the left side steering lever for support. Taking care
not to slip on the mower deck, step up onto the operator’s
platform and comfortably seat yourself. The park brake
lever just to your left and adjacent to the operator’s seat
should be fully raised and in the (ON) position. With both
steering levers still wide apart now reach for the throttle
and choke control to your right side. Position the throttle
control at half throttle and pull the choke to the “up/on”
position. Insert your ignition key and rotate the ignition
key clockwise until you hear the engine begin to start.
Release the ignition key and push the choke to
“down/off” position. Allow the engine to warm up
momentarily. If your mower has just been running and the
engine is already warm, using the choke is probably not
necessary.
With the engine at half throttle, release the parking brake
by pushing the lever forward and down all the way. Then
reach forward and bring both steering levers equally
together in the neutral position just in front of you. It’s now
time to test your steering skills. Gently push both steering
levers equally forward. The farther forward you push the
levers the faster you will go. Pull back equally and you will
slow down coming to a stop when you reach the neutral
position. Now slowly pull the levers back toward your
body past neutral position. The mower will reverse
direction and increase in speed as you pull further back.
If you push one lever forward and pull one lever back the
mower will do a zero turn in the direction of the steering
lever closest to your body. Now take a few moments in a
safe open area to practice maneuvering and steering
your mower with the engine still at half throttle. Gradually
increase your throttle speed until you feel totally confident
of your mower steering and handling ability around
obstacles and in tight areas.

It’s now time to cut the grass. Hopefully, you have already
removed any obstacles from the lawn that you do not
want run over. With your mower at half throttle, place your
right foot on the deck lift pedal and release and lower the
deck to your preset cutting height. With your right hand,
pull up on the cutting blade engagement knob and
increase the engine speed to full throttle. You may now
begin mowing. When you are done mowing or just want to
take a break, make sure you do all of the following.
• Park on level ground if possible.
• Disengage cutting blades.
• Throttle back.
• Place steering levers in wide-open neutral position.
• Engage park brake lever.
• Turn engine off and remove switch key.
• Step carefully off the left side of the operator’s
platform.
• You may want to chock the wheels as an added
measure of safety, if and when you must park on an
incline.
In the unlikely event that you lose electrical power and
the Riding Mower shuts completely down, you will lose
hydrostatic steering capability. Should the engine fail for
any reason and you need to push or pull the unit a short
distance for loading or servicing, make sure you open
bypass valves on the pumps using the bypass valve rods.
The Land Pride Zero Turn Mowers are designed to deliver
professional cutting quality, while delivering high
productivity and sustained comfort over extended
periods of operation. With just a little bit of practice you
should become very good at operating your mower. See
the “Features and Benefits” section of this manual for
additional product information and performance
enhancing options.

! WARNING
Unless specifically required, Do Not have engine running
when servicing or making adjustments to the mower. Place
both control levers in the park position and remove ignition
switch key. Read and observe all “Safety Warnings” and
“Important Notes” in this manual.
Seat Adjustment
Refer to Figure 3-1:
The seat should be adjusted forward or rearward to a
comfortable position to operate the deck lift pedal.
1.
a. Determine if the seat is too close to the pedal, too
far away, or at the correct distance.
Repairs or maintenance requiring engine power should be
performed by trained personnel only. To prevent carbon
monoxide poisoning, be sure proper ventilation is available
when engine must be operated in an enclosed area.
Your Zero Turn Mower was adjusted before it left the
factory and checked for proper operation during
pre-delivery set-up. However, break-in wear and
continued use can cause some adjustments to change.
• Be alert for unusual noises while operating the mower.
They could be signaling a problem.
• Visually inspect for abnormal wear or damage while
servicing and making adjustments to the mower.
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
!
WARNING
Keep your mower clean. Remove heavy trash and clippings
from mower. Keep all moving parts, hydraulic system, engine
cooling system, and exhaust system clean of trash and
clippings. Accumulation of trash and/or clippings can cause
fires, hydraulic overheating and excessive belt wear.
With operator seating in the seat, place his or her
right foot on the deck lift pedal.
b. If the seat is at the correct distance, skip to
“Steering Adjustments” on page 22.
c. If the seat needs adjusting, determine how many
inches it should be moved and in which direction it
should be moved. (forward or rearward)
2. Release spring loaded seat latch. See “Accessing
Area Beneath the Seat” on page 14 for instructions
on how to operating the spring loaded seat latch.
3. Rotate seat pan (#2) up and loosen all four
5/16"-18 x 3/4" GR5 cap screws (#3).
4. Slide seat forward or rearward by the predetermined
inches in step 1c above.
5. Retighten cap screws (#3) to the correct torque.
6. Rotate seat down until the spring loaded seat latch
catches on the seat pan.
7.
Reinstall removed hardware in seat latch to prevent
someone from opening the seat platform easily.
Clear away heavy build-up of grease, oil, and dirt.
Especially clean in the areas around oil openings, fuel
openings, and air inlets. Minute dust particles are
abrasive to close-tolerance engine and hydraulic
components.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel. Consult your Land Pride service center when
assistance is needed.
Torque Requirements
Refer to “Torque Values Chart” on page 52 to determine
correct torque values when tightening hardware. See
“Additional Torque Values” at bottom of chart for
exceptions to standard torque values.

Belt Tensioning
There are two drive belts on the ZST mower. The ground
drive belt is the upper belt that powers the mower rear
wheels (see Figure 3-4). The deck drive belt is the lower
belt that powers the mower deck blades (see Figure 3-6).
IMPORTANT: Do not over tension drive belts to
compensate for a badly worn belt or pulley.
An over tensioned belt can cause the belt and drive
components to break prematurely resulting in a
safety hazard to the operator and bystanders.
An under tensioned belt can cause the belt to slip
and become damaged.
Ground Drive Belt Tensioning
Refer to Figure 3-4:
The ground drive belt (#5) remains in constant tension by
means of a spring tensioned idler (#1). If belt slips under
normal operating load conditions, retention spring (#4) by
tightening eyebolt (#2). Replace belt when it becomes
excessively worn or damaged. Instructions for replacing
the ground drive belt are provided on page 34.
1.
Check length of ground drive extension spring (#4) to
verify if belt tension is correct. Installed spring length
should be 7" +/- 1/8" (See Figure 3-5).

Anti-Scalp Rollers
Refer to Figure 3-10:
The ZST40 mower has one anti-scalping roller (#3) and
the ZST48 mower has two anti-scalping rollers. Their
purpose is to minimize scalping of the ground when
mowing on rough uneven terrain. Their height should be
adjusted after setting the deck stop pin to the preferred
cutting height.
1.
Position mower and deck on a flat level surface.
2. Set deck to the preferred mowing height. (Refer to
“Deck Cutting Height and Leveling” on page 25.)
3. Remove 1/2" hex nylock jam nut(s) (#2).
4. Reposition anti-scalp roller(s) (#3) up or down in

IMPORTANT: The anti-scalp rollers will extend
below deck bottom the distance shown below when
mounted in the following holes:
• Top hole: rollers are even with deck bottom.
• 2nd hole: rollers are 1/2" below deck bottom.
• 3rd hole: rollers are 1" below deck bottom.
• 4th hole: rollers are 1 1/2" below deck bottom.
• Bottom hole: rollers are 2" below deck bottom.
For protection of deck and blades, it is best if the antiscalp rollers are mounted in the lowest holes
possible without them touching the ground.
For example:
If deck cutting height is set 1 1/2" above ground, the
rollers should be mounted in the 3rd hole down or 1"
below the deck bottom.
5. Secure anti-scalp rollers to mounting bracket(s) (#1)
with 1/2"-13 hex nylock nut(s) (#2). Tighten nut(s) to

Maintenance
!
DANGER
Regular maintenance is the best prevention for costly
downtime or expensive, premature repair. The following
pages contain suggested maintenance information and
schedules which the operator should follow on a routine
basis.
Exercise caution when working under the deck as the mower
cutting blades are extremely sharp. Wearing gloves is
advisable when working around or with cutting blades.
Check initially and periodically for loose bolts and pins.
Torque loose bolts per the “Torque Values Chart” on
page 52. Remain alert for unusual noises, they could be
signaling a problem. Visually inspect machine for any
abnormal wear or damage. A good time to detect
potential problems is while performing scheduled
maintenance service. Correcting problems as quickly as
possible is the best insurance.
Do not alter or replace parts with other brands on Land Pride
products. Other brands may not fit properly or meet OEM
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the product. Replace
parts only with genuine Land Pride parts.
Clear away heavy build-up of grease, oil, and dirt,
especially around the engine and under the seat
platform. Minute dust particles are abrasive to
close-tolerance engines and hydraulic assemblies.
Read and observe all safety warnings in this manual and in the
engine service manual.
Inspect mower daily for grass clippings, tangled wire, and
string. The underside of the mower deck will collect a
build-up of grass clippings and dirt, especially when
grass is wet or has high moisture content. This build-up
will harden, restricting blade and air movement, and will
usually produce a poor quality of cutting. Therefore,
debris should be routinely removed from under the deck.
To do this, it will be necessary to raise and block the deck
in the full up position before scrapping build-up from
underneath.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel. Consult your Land Pride dealer when
assistance is needed.
Maintenance Safety
!
DANGER
Repairs or maintenance specifically requiring engine power
should be performed by trained personnel only. Control levers
should be out. If control levers are to be operated, the tires
should be properly supported off the floor. Enclosed areas
should be properly ventilated to prevent carbon monoxide
poisoning.
!
DANGER
Before working on or under the deck, make certain blade
engagement switch has been shut off, deck has been properly
blocked up, engine has been shut off, and ignition switch key
has been removed for maximum safety.

Refer to Figure 5-5 or Figure 5-6 on page 33:
1. Park mower on a flat surface.
Before raising floor pan or removing pulley guards, make
certain blade engagement switch has been shut off, deck has
been properly blocked up, engine has been shut off, and switch
key has been removed for maximum safety. Replace all guards
and floor pan before putting mower back into service. Repairs
or maintenance requiring engine power should be performed
by trained personnel only.
2. Make sure blade engagement switch is (OFF),
control levers are fully (OUT), park brake is (ON), and
engine switch key is (OFF) and removed.
Refer to Figure 5-5 and Figure 5-6 on page 33:
Replace belts that show signs of severe cuts, tears,
excessive weather checking, and cracking or burns
caused by slipping. Slight raveling of belt covering does
not indicate belt damage. Trim ravelings with a sharp
knife.
6. Release deck belt tension with by placing a socket
wrench with a 3/4" socket on the over-center-release
bolt (#9) and turning counterclockwise. This will
relieve the tension on the tension idler spring (#11).
Inspect belt pulley grooves and flanges for wear. A new
belt or one in good condition, should never run against
the bottom of the groove. Replace pulley when this is the
case, otherwise belt will lose power and slip excessively.
8. Remove existing deck drive belt (#3).
Never pry a belt onto a pulley as this will cut or damage
the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition

Hydrostatic Drive System
!
1.
DANGER
Hydraulic fluid under pressure can penetrate skin. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Use a piece of cardboard or wood
rather than hands when searching for hydraulic leaks. If
hydraulic fluid is injected into the skin or eyes, it must be
treated by a doctor familiar with this type of injury within a
few hours or gangrene may result. DO NOT DELAY.
! WARNING
Always wear adequate eye protection when servicing the
hydraulic system.
IMPORTANT: Do not use a high pressure washer on
or around the hydraulic transaxles. Water intrusion
will result and void the warranty.
IMPORTANT: Oil changes and repairs to a transaxle
unit should be performed by trained technicians
Park mower on a flat level surface. Stop engine and
remove ignition key. Make sure blade engagement
switch is in the down (OFF) position. Spread
control levers fully apart and set park brake in (ON)
position.
2. Clean transaxle exterior of any debris especially
around the fill port cap. A degreaser may be needed.
3. Remove fill port cap.
4. Measure distance from top of fill port down to oil
level. This distance should be between 3/4" and
1 1/2" with oil temperature between 50o and 100o F.
5. Fill transaxle at the fill port with specified oil until oil is
at the correct lever (between 3/4" & 1 1/2" from top of
fill port). See page 45 for transaxle oil specifications.
6. Install top port cap and tighten.
7.
Recheck oil level once unit has be operated for
approximately 1 minute.
8. Purge each transaxle that has had oil added to
remove any air that may have become trapped. See
“Transaxle Purging Procedures” on page 36.
NOTE: The transaxle units are equipped with bypass
valves. For more information refer to “Moving Mower
with Stalled Engine” on page 14.
The ZST Series are equipped with two independent
Hydro-Gear ZT-2200TM Integrated Zero-Turn Transaxle
units. The units are located beneath the seat. See
“Accessing Area Beneath the Seat” on page 14 for
instructions to pivot seat platform up. These units are self
contained and maintenance free. They do not require oil
changes. However, if the oil has been contaminated or
has been added, an oil change may alleviate certain
performance problems. If needed, have your nearest
Authorized Land Pride Service department change your
mower’s transaxle. Check oil level in a transaxle only if it
shows signs of leaking, is operating hot, is noisy, or if unit
lacks power after operating it for a short time.
Transaxle Oil Check & Filling
Refer to Figure 5-8:
The mower has two independent hydrostatic transaxles.
Each transaxle will require separate oil checks. It is best
to check oil when the oil in the transaxle is between
50o and 100o F. See page 45 for oil specifications.

Transaxle Purging Procedures
Bypass Valve Rods
It is critical that air is purged from the hydrostatic drive
system to keep it efficient. This is because compression
and expansion rate of air is higher than that of oil. This
purge procedure should be implemented any time the
hydrostatic system has been opened to facilitate
maintenance or after oil has been changed.
Symptoms of a hydrostatic system that has not been
purged may be:
1.
Noisy operation.
2. Lack of power after operating mower a short time.
3. High operation temperature and excessive
expansion of oil.
IMPORTANT: Before purging system, make sure
transaxles are properly filled with oil. See
“Transaxle Oil Check & Filling” on page 35. For
transaxle oil specification, see page 45.
The following procedures are best performed with mower
rear drive wheels off the ground. Then repeated under
normal operating conditions. If this is not possible, then
the procedure should be performed in an open area free
of any objects or bystanders.
Refer to Figure 5-9:
1. Pull back and up on the bypass valve rod loop ends.
Continue to hold the loop ends up against the engine
platform while releasing the rod, The upturned ends
on the loops should catch on the platform locking the
transaxle in free wheeling.
2. Start engine and place both control levers in neutral.
Slowly move control levers completely forward and
reverse 5 to 6 times.
3. Close both bypass valves by pulling back on the rods,
lowering them down, and slowly releasing them to
allow the springs to pull back on the rods.

Clean dirt from around fuel tank cap. Remove cap and
begin filling. Do not fill fuel tank to the top. Fuel will
expand in hot weather and seep out through the fuel tank
vent system. When finished, screw cap back on until it
makes a clicking noise and ratchet action that can be
heard and felt when tight. Wipe up any spilled gasoline.
Use regular unleaded gasoline with an (R+M)/2 octane
rating of 87 or higher.
IMPORTANT: The fuel system can be damaged if
the wrong fuel is used. Never use methanol, lead
gasoline, or unleaded gasoline containing more than
10% ethanol. Do not mix oil with gasoline.
Land Pride recommends adding correct amounts of gas
stabilizer/conditioner in the fuel. For best results, follow
engine manufacturer’s directions. Using a fuel stabilizer/
conditioner in the fuel can provide benefits such as:
1.
Keeps gasoline fresh during storage of 90 days or
less. Drain fuel tank if storage is longer.
4. With engine running and control levers in neutral,
slowly move levers forward and reverse 5 to 6 times.
2. Cleans engine during operation.
5. Stop engine and check oil level in transaxles.
3. Eliminates gum-like varnish build-up in the fuel system.
IMPORTANT: The transaxle is considered purged
when transaxles are at the proper oil level, operate
at normal noise levels, oil temperatures are not
excessively high, and mower does not lack power.
6. It may be necessary to repeat Steps 1 to 5 until all air
is purged from the system and transaxle operates at
normal noise levels and travels at normal speeds.

DANGER
• Replacement of fuel system parts (i.e. gas caps, hoses, fuel
tanks, fuel filters, etc.) must be the same as original parts.
Fire and/or explosion can occur if not followed.
• Observe safe fuel handling precautions. Fuel is flammable
and vapors are very explosive. An explosion or fire can
burn, destroy and kill property, animals and people.
• Do not fill tank while engine is running or hot. Allow engine
to cool before filling. Fuel spilled over engine, muffler, or
hot objects may result in a fire or explosion.
• Allow engine to cool before servicing the fuel system.
• Do not smoke while handling fuel or around the fuel tanks.
• Do not fill fuel tanks to the top. Fuel will expand in hot
weather and seep out through the fuel tank vent system.
• Screw gas cap on immediately after filling a tank. Never
operate mower without gas caps installed.
• Clean up any gasoline spills immediately.
• Keep fuel away from open flame or spark.
• Store mower away from open flame and sparks.
• Refuel outdoors preferably, or in well ventilated areas.
• Never attempt to start the engine when there is a strong
odor of gasoline fumes present. Locate and correct cause.
• Never buy more than a 30 day supply of gasoline and store
it in an approved container out of children’s reach.
• Do not fill gasoline containers inside a vehicle, on a truck,
or on a trailer. Interior carpets and plastic truck bed liners
insulate the container and slow loss of static charge.
• When practical, remove equipment from the truck or trailer
and refuel the equipment with its wheels on the ground. If
this is not possible, then refuel the equipment on the truck
or trailer using a portable container and not a gasoline
dispenser nozzle. If a gasoline dispenser nozzle must be
used, keep nozzle in contact with rim of fuel tank or
container opening at all times until fueling is complete.
• Gasoline is a poison that is harmful or fatal if swallowed.
• Avoid prolonged breathing of vapors. Long-term exposure
to vapors can cause serious injury and illness
• Keep face away from nozzle and gas tank opening.
• Keep gas away from eyes and skin.
Evaporative Emission Control
System
All Land Pride Zero Turn Mowers will be EPA compliant
on the required January 1, 2012 date. Mowers that are
EPA compliant now have a decal on them stating: “This
Equipment meets U.S. EPA Evap. Standards”. The
Evaporative Emission Control System requires no
regularly scheduled maintenance but should be
inspected periodically, and thoroughly examined at least
once a year at the beginning of the mowing season:
1.
Inspect all fuel system components including tank,
vent, hoses, clamps, fuel filter, valve, and fittings for
leaks, cracks, and loose connections. Make repairs
as necessary.
3/16/17
2. The fuel tank is equipped with a tethered cap. Ensure
tether is present and secured to the cap.
3. The fuel cap has been designed to provide audible
and tactile feedback indicating that proper sealing
has been achieved. Ensure that this function is
present and that no fuel leaks from the filler neck
during usage. If fuel leakage is ever noticed at this
point, the fuel cap must be replaced immediately.
Fuel Filter
Refer to Figure 5-12 on page 38:
!
DANGER
Empty fuel tank before replacing fuel filter to keep fuel from
leaking out and creating a fire/explosion hazard.
The fuel filter is installed in the fuel line between the
fuel tank and engine fuel pump. Location of fuel filter will
vary depending on which engine your mower is equipped
with. See engine owner’s manuals for exact location of
fuel filter and instructions on removal and installation.
Refer to Figure 5-11:
Replace fuel filter annually at the beginning of each
mowing season or after every 100 hours of operation,
whichever occurs first. (Plugged filter considered
maintenance item.) This will keep the fuel filter from
becoming plugged causing poor engine performance
and unexpected downtime. Be sure to install filter with
Flow Arrow pointing towards engine side of fuel line.

Engine Air Filter
Improper Installation
A specially designed dry filter is standard equipment and
supplies clean combustion air to the engine.
Improper installation occurs when dust leaks past the
seals. The filter element must be aligned within the
canister and properly seated on both ends to prevent dirt
from entering the engine.
NOTE: Do not operate engine with a damaged air filter
or without an air filter element. Dirt will enter the
engine causing dust induced engine damage.
Damaged Air Filtering System
NOTE: Do not block air intake to the filter such as
setting an object in front of the air intake opening.
A damaged air filtering system occurs from mishandling
of the filter element and operating the mower in areas
that could damage the canister.
Refer to Figure 5-12 on page 38:
Kawasaki engines are supplied with internal air filters.
Perform engine air filter maintenance per the Engine
Operator’s Manual and “Maintenance Schedule” on
page 30.
Air Filter Handling
Refer to Figure 5-12:
Prevent costly and non-warrantable premature engine
damage by maintaining the air filter properly. Many
engine problems are due to improper handling of the air
filter. Dust and dirt that gets past the air filter will damage
engine cylinder, piston, and bearings in a few hours.
Avoiding the following common mishandling:
• Over servicing
• Improper installation
• Damaged air filtering system
• Incorrect air filter element
Over Servicing
Over servicing occurs when an air filter element is
inspected and/or replaced too often. Dust and dirt can fall
off the filter element onto the canister where it can be
drawn into the intake system. Only a few grams of dirt
getting into an engine during each filter inspection can
prematurely produce dust induced engine damage. A
partially dirty air filter element is not harmful to the
engine.
Banging and/or bumping the filter element against a solid
object such as a tire or blowing the element with air can
damage the seals and/or force dust and dirt particles
through the filter media creating a hole for dirt to pass
through to the engine.
Driving the mower carelessly over rough terrain, jutting
sticks, heavy brush, and severe rocks can damage the air
cleaner canister. Periodically inspect the outside of the
air cleaner canister for external damage and replace if
necessary.
Incorrect Air Filter Element
The air filter must remain intact to block passage of dirt
and foreign particles. It must be of sufficient size and
construction to withstand stresses, caused by rapid
cycling of air volume demanded by the engine, without
cracking or tearing under fatigue and pressure. Its filter
elements must have the correct media composition, filter
area, micron size, and dimensions to properly filter the air
of dirt while at the same time passing sufficient air to the
engine.
Land Pride and the engine manufacturers have carefully
selected a reliable filter designed to fit these needs.
Always use genuine Land Pride filters. Failure to use
original equipment replacement parts is an alteration
and will not be considered for warranty in the event
of a dust induced engine damage. See “Engine
Specifications & Capacities” on page 45 for Land Pride
air filter replacement numbers.
The air filter element should be changed before it
becomes too dirty and restricts air flow to the engine
hindering its performance. Replace the air filter element
immediately should this happen. Engines that do not get
proper amounts of air will draw in excessive amounts of
gas causing premature engine damage.
The frequency of the air filter needing changing is largely
determined by operating conditions. Dusty conditions will
require more frequent servicing.
A dirty filter element should always be replaced with a
new element. Improper cleaning procedures can get dust
on the inside of the filter causing dirt induced and engine
damage. The air filter warranty expires upon cleaning
or servicing a used filter in any manner. Land Pride
does not warranty dust induced engine damage if a
used air filter element has been cleaned or serviced
in any manner.

Mower Blade Maintenance
Blade Sharpening
Blade Inspection
Check mower blades daily, they are the key to power
efficiency and well groomed turf. Keep them sharp as a
dull blade will tear rather than cut grass, leaving a brown
ragged top on the grass within a few hours. A dull blade
also requires more power from the engine.
!
Replace any blade which is bent, cracked, or broken.
!
!
CAUTION
ALWAYS wear eye protection and gloves when sharpening a
blade.
WARNING
DO NOT try to straighten a blade that is bent. Never weld a
broken or cracked blade. ALWAYS replace with a new Land
Pride blade to assure safety.
!
DANGER
Keep blades balanced when sharpening. An unbalanced blade
may come loose and fly out from under the deck. Also, an
unbalanced blade will shorten the spindle bearing’s life.
NOTE: Care should be taken in order not to remove
any more material than necessary to sharpen blade.
1.
DANGER
Never work with blades while engine is running or with blades
engaged. Always push blade engagement switch down (OFF),
move both control levers to neutral and then fully (OUT), set
park brake (ON), and turn engine (OFF). Block up mower
when you must work under it. Wear gloves when handling
blades. Always check for blade damage if mower should strike
a rock, branch, or other foreign object during mowing.
Clean blade, blade washer, and mounting surface of
all debris before inspecting blade and sharpening.
Refer to Figure 5-14:

Section 5: Maintenance & Lubrication
Refer to Figure 5-16:
NOTE: New mower blades are furnished with
cutting edge parallel with back of blade. Do not
sharpen blade to original parallel pattern. It is easier
to get a straight cutting edge by resharpening the
pattern to the one shown in Figure 5-17.
Refer to Figure 5-18:
6. Remove an equal amount of material from each end
of the blade to keep blade in balance. Check blade
balance as follows:
a. Positioning center of blade horizontally on a nail
or shaft. See Figure 5-18.
b. If either end of the blade rotates downward, grind
(remove) metal on that end until the blade will
balance horizontally on the nail or shaft.
c. Resharpened blades can be installed after they
have been properly sharpened and balanced.

Blade Installation
Refer to Figure 5-13 on page 40:
a. Grind cutting edge at the same bevel as the
original angle. (27 1/2 degrees).
b. Sharpen only the top of the cutting edge to
maintain sharpness.
c. Touch-up sharpening can be done with a file.

WARNING
!
WARNING
When mounting blades, rotate them after installation to ensure
blade tips do not touch each other or sides of the mower.
Failure to torque blade bolt properly may result in the blade
coming loose and falling off causing a serious injury.
IMPORTANT: Replace mower blades with Land
Pride blades only.
Resharpening Cutting Edge Pattern
IMPORTANT: Always install blades with cutting edge
facing direction of blade spindle rotation and with
wing tips pointing up towards bottom of deck. For
correct blade rotation, see arrow in Figure 5-13.

IMPORTANT: Do not re-use blade bolts which have
stripped, worn or undercut threads. For proper blade
bolt torque value. see “Additional Torque Values”
on this page.
1.
Install resharpened or new blade (#4) with blade
washer (#3) and blade bolt (#2). Be careful not to
cross thread blade bolt while installing it.
2. Tighten blade bolt to the correct torque. See
“Additional Torque Values” on page 52 for correct
torque values.

End of Season & Long Term Storage
8. Store mower in a clean, dry place.
Take the following steps when storing the mower at the
end of the season and when the unit will not be used for
long periods to ensure readiness for the next mowing
season.
9. Block mower up so weight is off the tires.
IMPORTANT: Do not use a high pressure washer on
or around the hydraulic transaxles. Water intrusion
will result and void the warranty.
1.
Remove all grass, dirt, trash, and grease that may
have accumulated on the mower and moving parts.
2. Scrape off compacted dirt, trash, and grass clippings
from the deck underside. A coating of oil may also be
applied to the deck underside to minimize oxidation.
NOTE: Do not deflate tires.
10. Protect battery from freezing temperatures.
Disconnect the negative ground wire from battery to
reduce chances of a slow electrical drain.
Occasionally recharging battery during storage will
extend battery life.
New Season Preparation
The following service is required before starting the
mower after storing it for a season:
IMPORTANT: Do not use a high pressure washer on
or around the hydraulic transaxles. Water intrusion
will result and void the warranty.
3. Clean and touch up all scrapes with Land Pride spray
paint.
4. Check blades and blade bolts for wear and replace if
necessary.
1.
Clean mower, removing trash, and dirt accumulation.
5. Check thoroughly for any worn or damaged parts
that need replacing and order them from your
nearest Land Pride dealer.
2. Check engine oil level.
6. Thoroughly lubricate machine, according to
lubrication instructions.
4. Install all safety shields and review safety
precautions listed in this manual.
7.
5. Check and inflate tires to correct psi provided in
“Tire Inflation Chart” on page 53.
Prepare engine for storage:
a. Run engine for a minimum of 15 minutes.
3. Tighten any bolts that have loosened and make sure
all hair pins, cotter pins, and clevis pins are in place.
b. Drain oil from crankcase while engine is still
warm.
6. Fill fuel tank with fresh gasoline.
c. Refill with fresh oil of proper viscosity. Refer to
“General Engine Maintenance” on page 38 and
“Engine Specifications & Capacities” on page
45.
8. Run machine at half speed for 5 minutes, checking
operation of the control levers. Stop engine and
check for oil leaks, loose fittings, and so forth.
7.
Reconnect spark plug leads to spark plug.
d. Drain fuel tank and run engine until it stops from
lack of fuel. Gasoline evaporates if left in
carburetor for long periods, forming gum, and
varnish deposits in the carburetor. These deposits
will cause engine flooding and loss of power.
e. Service air cleaner. See “Engine Air Filter” on
page 39.
f. Remove and replace fuel filter if not done in the
previous 100 hours.
g. Remove spark plugs and pour a tablespoon of
engine oil into each spark plug hole. Install plugs,
but do not reconnect plug leads.
h. Crank engine with starter at least a dozen
revolutions to distribute oil over cylinder walls and
valve mechanism.
i. Clean dirt and chaff from cylinder fins, blower
housing, and muffler.
j. Clean exterior surface of engine. Spread a light
film of oil over any exposed metal surfaces of
engine that are subject to corrosion.
k. Check oil fill cap and fuel tank caps to make
certain they are securely in place.
