the engine while the engine is running
(e.g. carburetor), disengage all clutches

Be careful of heated surfaces and muffler.
Minor carburetor adjustments may be required to
compensate for differences in fuel, temperature,
altitude and load. Refer to separate engine manual
for carburetor adjustment information.
NOTE: A dirty air cleaner will cause an engine to run
rough. Be certain air cleaner is clean and attached to
the carburetor before adjusting carburetor.

shooting engine problems.
CRANKCASE OIL
Check the oil level in the crankcase before each use
of the machine and after every two hours of operation.
Oil level should be maintained as instructed in the
separate engine manual.
After the first two hours of operating a new engine, drain
the oil from the crankcase while engine is still hot and
refill crankcase with new oil; thereafter change the oil
after every 25 hours of operation. Refer to the engine
manual.
FUEL FILTER
Your unit is equipped with a replaceable in-line fuel
filter. Replace filter whenever contamination or
discoloration is noticed. Order replacement filter
through your authorized engine service dealer.
WHEEL ADJUSTMENT
The caster (forward slant of the king pin) and the

justment. Automotive steering principles have been
used to determine the caster and camber on the trac¬
tor. The front wheels should toe-in 1/8 inch.
