grass screen, cooling fins, and other exter-
nal surfaces of the engine are kept clean
at all times.
Every 100 hours of operation (more often
under extremely
dusty, dirty conditions),
remove the blower housing and other cooling
shrouds. Clean the cooling fins and external
surfaces as necessary. Ensure the cooling
shrouds are reinstalled.
NOTE: Operating the engine with a blocked
grass screen, dirty or plugged cooling fins,
and/or cooling shrouds removed wilt cause
engine damage due to overheating.

Protect painted surfaces with automo-
tive type wax.
We do not recommend using a garden hose
or pressure washer to clean your tractor
unless the engine and transmission
are
covered to keep water out. Water in engine
or transmission will shorten the useful life of
your tractor.
Use compressed
air or a leaf
blower to remove grass, leaves and trash
from tractor and mower.
