Battery Storage
When storing the tractor for extended periods, disconnect 
the negative battery cable. It is not necessary to remove
the battery.
All batteries discharge during storage. Keep the exterior 
of the battery clean, especially the top. A dirty battery will
discharge more rapidly.
The battery must be stored with a full charge. A discharged 
battery can freeze sooner than a charged battery. A fully
charged battery will store longer in cold temperatures than
hot.
Recharge the battery before returning to service. Although 
the tractor may start, the engine charging system may not
fully recharge the battery.
Tractor Storage
If your tractor is not going to be operated for an extended period
of time (thirty days to approximately six months), the tractor
should be prepared for storage. Store the tractor in a dry and
protected location. If stored outside, cover the tractor (including
the tires) to protect it from the elements. The procedures
outlined below should be performed whenever the tractor is
placed in storage.
Change the engine oil and filter following the instructions 
provided in the engine manual packed with this manual.
Never store the tractor with fuel in the
tank indoors or in poorly ventilated enclosures,
