Starting The Tractor With Jumper Cables; Stopping The Engine; Break-In Procedures - New Holland TC21D Operator's Manual

STARTING THE TRACTOR WITH
JUMPER CABLES
WARNING
Start the engine only from the operator's seat. If
safety start switches are bypassed, the engine
can start with the transmission and/or PTO in
gear.
If you must use jumper cables to start the tractor:
1. Shield your eyes.
2. Connect one end of the jumper cable to the
tractor battery positive (+) terminal and the other
to the auxiliary battery positive (+) terminal. Next,
connect one end of the other jumper cable first to
the auxiliary battery negative (-) terminal, then
the other end to the tractor starter ground
terminal. Finally, start the tractor by following the
safe starting procedures outlined under "Starting
the Engine." Idle the engine and turn on all
electrical equipment (lights, etc.), then discon-
nect the jumper cables in the reverse order in
which they were connected. This helps protect
the alternator from damage due to extreme load
changes.
WARNING
Batteries contain sulfuric acid and produce
explosive gases. To prevent personal injury:
Wear eye and skin protection.

BREAK-IN PROCEDURES

Your New Holland tractor will provide long and
dependable service if given proper care during the
first 50-hour break-in period. During the first 50 hours
of operation:
1. Avoid "lugging" the engine. Operating in too high
a gear under heavy load may cause engine
lugging, which is indicated when the engine will
not respond to a throttle increase.
2. Use the lower gear ratios when pulling heavy
loads and avoid continuous operation at
constant engine speeds. You will save fuel and
minimize engine wear by selecting the correct
gear ratio for a particular operation. Operating
the tractor in low gear with a light load and high
engine speed wastes fuel.
3. Avoid prolonged operation at either high or low
engine speeds without a load on the engine.
4. Check the instruments frequently and keep the
radiator and oil reservoirs filled to recommended
levels. Daily checks include the engine oil level,
radiator coolant, and air cleaner.
5. After the first 50 hours of use, be sure to perform
the maintenance items listed in the maintenance
schedule.
