MAINTENANCE
AFTER EACH USE
Clean the under side of the deck of grass clippings to prevent
a build-up from hampering the efficiency of the mower.
Remove the mower from the tractor to clean it thoroughly;-

Note:
DO NOT remove the arbors.
Remove the blades
from the arbors. To sharpen a blade yourself, clamp it in a
vise and use a 10 inch file along the original bevel. File to a
razor edge.
To balance, insert a knife blade or small rod
through the center hole to see if blade rests with both ends
balancing evenly. File heavy side until even.

ALWAYS HANDLE BLADES WITH CARE TO
AVOID INJURY.
the mower. Be careful not to get oil on the belts. See Fig. 19)
EVERY 50 HOURS or ONCE EACH SEASON
Remove paint and dirt from the zerks on the arbors and
put five shots of grease in each one.

BLADE REPLACEMENT
Do not attempt to remove the blades until you have the
correct size box,socket or open end wrenches for the blade
mounting bolts.
Carefully clean the blade and arbor.
Install the new or
sharpened blade with the lift tabs toward the top. Install
the two blade mounting screws and tighten the bolts alter¬
nately two turns at a time to 30 ft. lbs. torque. Use a block
or wedge to keep the blade from turning while tightening
bolts. Rotate the blades by hand slowly to see that the ends
clear the housing all around and the tips are running true.
If the mower is properly adjusted and in apparent good con¬
dition, but seems to require excess engine power, it may be
that an arbor shaft or sleeve has been damaged by hitting an
obstruction.
Check the blade drive system.
The rotor
spindles should turn with one or two lbs. pull on the blade
with the drive belt removed. If the pull pressure exceeds
two lbs., the unit is robbing power from the engine. Tight
bearings, a bent arbor shaft or spindle housing can be re¬
paired or replaced by your Simplicity dealer.
