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.
Inspect mower daily 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 35.
For engine torque values, see engine owner’s manual.
