water, but must be dry when used.

or deterioration. Through normal use itwill
wear. if catcher needs replacing, replace
only with a manufacturer approved

you mow to be sure they move freely.
The wheels not turning freely means trash,
grass cuttings, etc. are in the drive wheel
area and must be cleaned to free drive
wheels.
If necessary to clean the drive wheels,
check both front wheels.

washers.
= Remove wheels from wheel adjusters.

inside the dust cover, pinion and/or drive
wheel gear teeth.

turn freely, contact your nearest
authorized service center.

properly, the gear case and area around
the drive should be kept clean and free
of trash build-up. Clean under the drive
cover twice a season.
