GRASS CATCHER
• The grass catcher may be hosed with water, but must
be dry when used.
• Check your grass catcher often for damage or de te-
ri o ra tion. Through normal use it will wear. If catcher
needs replacing, replace only with ap proved replace-
ment catcher shown in the Repair Parts section of this
manual. Give the lawn mower model number when
ordering.
GEAR CASES
• To keep your drive system working properly, the gear
cases and area around the drive should be kept clean
and free of trash build-up. Clean under the drive cover
twice a season.
• The gear cases are filled with lubricant to the proper level
at the fact ory. The only time the lubricant needs atten-
tion is if service has been performed on the gear case.
ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service
classification SG–SL. Select the oil's SAE viscosity grade
according to your expected operating temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve
starting in cold weather, and you should check your engine
oil level frequently to avoid possible engine damage from
running low on oil.
Change the oil after every 25 hours of operation or at least
once a year if the lawn mower is not used for 25 hours in
one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Tighten oil
plug securely each time you check the oil level.
TO CHANGE ENGINE OIL (See Fig. 16)
NOTE: Before tipping lawn mower to drain oil, empty fuel
tank by running engine until fuel tank is empty.
