Changing Engine Crankcase Oil
Change the engine crankcase oil
after every 100
hours
of operation as follows:
1. Park the mower on a
level surface with the
en gine stopped.
The engine oil should be
warm before draining. If not warm from opera
tion, start the engine and run a few minutes to
warm the oil.
2. Before removing the dipstick, clean the area
around the dipstick to keep any dirt or debris out
of the en gine.
3. Remove the dipstick and the oil drain plug and
drain the oil into a suitable container. Be sure
to allow ample time for complete drainage.

4. Reinstall the drain plug. Make sure it is tight
ened to 13 lb
·
ft (17.6 N
·
m).
5. Fill the crankcase (through the dipstick tube)
with new, clean oil. Use only crankcase lubri
cants recommended by the engine manufac
turer. Refer to
Specifications
in this manual or
the engine owner’s manual. Use the recom
mended oil viscosity for the expected ambient
temperature. Oil with the correct viscosity will
aid starting in cold weather and assure proper
lubrication in hot weather.
Fill to FULL (F)
mark
on the dipstick; crankcase capacity is 1.2
quarts (1.1 liters).
IMPORTANT:
Check the dipstick reading be-
fore
adding the last 1/2 pint of oil and
fill only to
the FULL (F) mark.
The oil level should never
be over the
FULL (F)
mark on the dipstick; over
filling can result in engine overheating and loss
of power.
6. Start and run the engine. Stop the engine, re
check the oil level, and add oil if necessary.
Grease Fitting and Oil Point Lubrication
Lubricate the grease fittings and oil points after
ev-
ery 25 hours
of operation. Lubricate
more often
when operating in
dusty or dirty conditions.
Use
SAE general purpose lithium or molybdenum base
grease for grease fittings and light machine oil
(SAE 10) to lubricate oil points.
Lubricate the
locations shown in the Chassis and Deck
Lubrication Points illustration.
NOTE:
PTO universal joints (on the deck and trac
tor) require routine lubrication
after every 25
hours
of running time. Refer to
PTO U-Joint Lu-
brication (Tractor)
in this section for lubricating U-
Joint on tractor.
NOTE:
The ball bearings on the PTO drive shaft are
sealed and do not require periodic maintenance.
