Tractor Boosting
1. Set the park brake, put the transmission in
neutral, PTO clutch control and all
accessories OFF.
2. Attach one end of the booster cable to the
positive terminal of the booster batteries and
the other end of the same cable to the
positive terminal of the center battery on the
tractor.
3. Attach one end of the negative cable to the
negative terminal of the booster battery, and
the other end of the same cable to a ground
on the tractor frame at least 305 mm (12″)
from the discharged batteries. DO NOT
CONNECT TO THE NEGATIVE POST OF
THE DISCHARGED BATTERIES.
4. Be sure that the clamps from one cable do
not touch the clamps of the other cable. Do
not lean over the battery when making
connections.
5. Start the tractor following normal engine
starting procedures.
6. When the tractor starts, remove the booster
cables. Disconnect the negative cable, then
the positive cable.
7. If the tractor fails to start, charge the
batteries.
All models have three batteries connected in
parallel that have 950 CCA (BCI Group 31).
CAUTION: WHEN SERVICING
BATTERIES, DISCONNECT THE
NEGATIVE (BLACK) CABLES BEFORE
THE POSITIVE (RED) CABLES. WHEN
CONNECTING CABLES, CONNECT THE
POSITIVE (RED) CABLE FIRST, THEN
THE NEGATIVE (BLACK). THIS WILL
REDUCE THE POSSIBILITY OF
SPARKING AND BATTERY EXPLOSION.
WARNING: ALL BATTERIES GENERATE
HYDROGEN GAS, WHICH IS HIGHLY
FLAMMABLE. IF IGNITED BY A SPARK
OR FLAME, THE GAS MAY EXPLODE
VIOLENTLY CAUSING A SPRAY OF ACID,
FRAGMENTATION OF THE BATTERY,
AND POSSIBLE SEVERE PERSONAL
INJURY, PARTICULARLY TO THE EYES.
THEREFORE, AS A SAFETY
PRECAUTION:
WEAR PROTECTIVE CLOTHING AND
GOGGLES.
DO NOT SMOKE OR EXPOSE THE
BATTERY TO OPEN FLAME.
DO NOT CONNECT OR DISCONNECT
LIVE CIRCUITS.
FOLLOW THE CONNECTION
PROCEDURE AS OUTLINED ABOVE.
