NOTE: Change oil after first five (5) hrs. of operation. Follow engine
manufacturer's recommendations for future oil changes.
a) Disengage PTO.
b) Stop engine and wait for all moving parts to stop. Remove key or spark plug

unit has been sitting for awhile, run engine for a few minutes to get it warm.
d) Remove the oil drain plug from the right hand side of the engine. Allow oil to
drain, replace drain plug.
e) Replace the oil filter per the engine owners manual. Clean around oil filter and
unscrew filter to remove. Before the new filter is installed, apply a thin coating
of oil on the surface of the rubber seal. Turn filter clockwise until rubber seal
contacts the filter adapter, then tighten filter an additional 2/3 to 3/4 turn.

cap. Refer to Engine Owner's Manual for correct oil level and the SAE Grade
recommended by the manufacturer.
Do Not overfill.

5.1.9 Check tire pressures.
Service Interval: Pneumatic (air-filled) Drive Tires- 40 hrs.
a) Stop engine and wait for all moving parts to stop. Remove spark plug wire(s).
Check air pressure in drive tires; recommended tire pressure is: 12 to 16 psi
(83-110 kPa).
b) Inflate tires to pressures stated above. Measure the circumference of each
drive tire. Adjust tire pressures within the above range to try to make tire
circumferences match as closely as possible.
5.1.10 Check grease level, input and output shaft bearing wear on Peerless
Transmission. (Replace gearbox grease yearly)
Service Interval: 160 hrs.
a) Stop engine and wait for all moving parts to stop. Remove key or spark plug

the transmission. Replace bearings if necessary.
g) Remove the six bolts that fasten the upper case to the lower case and
carefully remove the upper case half.
h) Check the grease level in the lower case. The grease level should be
approximately 1-1/2" to 1-3/4" (3.8 to 4.4 cm) from the gearbox bottom. If
necessary, fill to proper level with Peerless grease (Part No. 788067).
