correct type.
Install only the type of batteries specified in the table below onto the windrower:
Table 6.7 Battery Specifications
Rating
Heavy duty, off-road,
vibration resistant

Maintaining Battery

The battery interacts with more parts in your machine than you may think or know exist. Keeping on top of routine
maintenance of the battery helps to lengthen its life and keep you ahead of any real problems that could arise.
CAUTION
Do NOT attempt to service a battery unless you have the proper equipment and experience to perform the job.
• Check the battery charge once a year, and more often if operating in cold weather. Hydrometer readings should be
1.260 to 1.300. Readings below 1.250 indicate charging is required. For instructions, refer to
375.
• Keep the batteries clean by wiping them with a damp cloth.
• Keep all connections clean and tight. Remove any corrosion and wash the terminals with a solution of baking soda and
water. A light coating of grease on the terminals (after the cables are attached) will reduce corrosion.
• To prolong battery life, store the batteries fully charged and at -7° to +26°C (+20° to +80°F). Check the voltage after
storage and recharge the batteries as needed according to the battery and charger manufacturer recommendations.
• Do NOT stack storage batteries on top of each other.
• Test the batteries every 4–6 months and recharge them if necessary.
• Disconnect the battery ground if storing the windrower for more than 3 months.

Opening Battery Cover

The windrower's battery cover may need to be opened for service, storage, or replacement. The battery cover protects the
battery from moisture, dust, and corrosion.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key from the ignition before leaving the operator's seat for any reason.
