Maintenance

WARNING!

Unless speciﬁcally required, DO NOT have engine running

when servicing or making adjustments to mower. Place control

levers in the neutral position, disengage blade engagement, and

remove ignition switch key. 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. Read and observe safety warnings in front of

manual.

DANGER!

Before working on or under the deck, make certain engine

cannot be accidentally started. Shut engine off and remove

ignition switch key for maximum safety. Repairs or maintenance

requiring engine power should be performed by trained

personnel only.

DANGER!

Exercise caution when working under the deck as the mower

blades are extremely sharp. Wearing gloves is advisable when

working around or with the blades.

WARNING!

Except when changing or checking belt, always keep belt covers

on mower for safety as well as cleanliness.

WARNING!

When possible, clean under mower using a stick or similar

instrument making sure that no part of the body, especially arms

and hands are under mower.

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.

Remain alert for unusual noises, they could be signaling a

problem. Visually inspect the machine for any abnormal

wear or damage. A good time to detect potential problems

is while performing scheduled maintenance service.

Correcting the problem as quickly as possible is the best

insurance.

WARNING!

Keep your machine clean and remove any deposits of trash and

clippings which can cause engine ﬁres and hydraulic

overheating as well as excessive belt wear.

Clear away heavy build-up of grease, oil and dirt,

especially in the engine and under the seat platform area;

minute dust particles are abrasive to close-tolerance

engine and hydraulic assemblies.

Daily inspect mower for grass clippings and wire and

string tangles. 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

probably show a poorer quality of cutting. Therefore it

should be removed routinely.

To do this it will be necessary to raise and block the deck

in the full up position and scrape the 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.

Torque Values

WARNING!

Particular attention must be given to tightening the drive wheel

lug nuts and blade spindle nuts. Failure to correctly torque

these items may result in the loss of a wheel or blade, which can

cause serious damage or personal injury.

It is recommended that these be checked after the first 2

hours of initial operation and every 50 hours following

removal for repair or replacement.

For all other torques refer to “Torque Values Chart”

page 39.

For engine torque values, see engine owner’s manual.

same amount of air pressure.
