Before performing any

maintenance or repairs, disengage PTO,
move shift lever into neutral position, set
parking brake, stop engine and remove key to
prevent unintended starting.

Refer to the Briggs & Stratton Operator/Owner 
Manual   for engine maintenance instructions.

Check engine oil level before each use as instructed in 
the Briggs & Stratton Operator/Owner Manual packed 
with your unit. Follow the instructions carefully.

For draining oil from the engine’s crankcase of select 
model tractors, a plastic oil drain sleeve is packed with 
this Operator’s Manual. To drain the oil, proceed as 
follows:

•

Unscrew the oil fill cap and remove the dipstick 
from the oil fill tube.

•

Snap the small end of oil drain sleeve onto the oil 
sump. See Figure 13.

•

Remove drain plug and drain oil into a suitable 
container with a capacity of no less than 64 oz.

•

Service the oil filter (if so equipped) as instructed 
in the separate Briggs & Stratton Operator/Owner 
Manual packed with your unit.

Perform the above steps in the opposite order after oil 
has finished draining. 

•

Refill the engine with new motor oil.

 Refer to the Briggs & Stratton Operator/

Owner Manual packed with your unit for information 
regarding the quantity and proper weight of motor oil.

Service the pre-cleaner, if so equipped, and cartridge/
air cleaner element as instructed in the Briggs & 
Stratton Operator/Owner Manual packed with your unit.

The spark plug(s) should be cleaned and the gap reset 
once a season. Spark plug replacement is 
recommended at the start of each mowing season. 
Refer to the Briggs & Stratton Operator/Owner Manual 
for correct plug type and gap specifications.

Before lubricating, repairing, or

inspecting, always disengage PTO, move
shift lever into neutral position, set parking
brake, stop engine and remove key to prevent
unintended starting.

Lubricate the engine with motor oil as instructed in the 
Briggs & Stratton Owner Manual packed with your unit.

Lubricate all the pivot points on the drive system, 
parking brake and lift linkage at least once a season 
with light oil.

The rear wheels should be removed from the axles 
once a season. Lubricate the axles and the rims well 
with an all-purpose grease before re-installing them.

Each end of the tractor’s front pivot bar may be 
equipped with a grease fitting. Lubricate with a grease 
gun after every 25 hours of tractor operation.
