BREAKING-IN PROCEDURE
Your new tractor will provide long and dependable
service if given proper care during the 50-hour
breaking-in period and serviced at the recommended
intervals.
Avoid prolonged operation at either high or low
engine speeds without a load on the engine.
Avoid overloading the engine. Operating in too high
a gear under heavy load may cause excessive
overloading. Overloading occurs when the engine
will not respond to a throttle increase.
Use the lower gears when pulling heavy loads, and
avoid continuous operation at constant engine
speeds. Operating the tractor in too low a gear with
a light load and high engine speed will waste fuel. You
will save fuel and minimize engine wear by selecting
the correct gear for each particular operation.
Check the instruments frequently and keep the
radiator and oil reservoirs filled to the recommended
levels.
