Changing Engine Crankcase Oil
Change the engine crankcase oil after every 50
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 it to keep any dirt or debris out of the
en gine.
3. Remove the dipstick and oil drain plug, and
drain 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 16.5 lb·ft (23 N·m).
5. Fill the crankcase (through the dipstick open-
ing) with oil using only crankcase lubricants rec-
ommended by the engine manufacturer. Refer
to Specications in this manual or the engine
owner’s manual. Use the recommended oil vis-
cosity 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 (H) mark on the dip-
stick; crankcase capacity is 2.7 pints (1.3 liters).
IMPORTANT: Check the dipstick reading be-
fore adding the last 1/2 pint of oil and ll only to
the FULL (H) mark. The oil level should never
be over the FULL (H) mark on the dipstick; over-
lling 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 ttings 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 ttings 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 8 hours
of running time.
NOTE: The ange bearings on the PTO drive shaft
are sealed and do not require periodic maintenance.
