Yanmar YM4220 Extra Battery Notes
Bad battery symptoms
A weak or failing battery in a Yanmar YM4220 tractor often causes hard starting, a clicking sound when turning the key, or no response at all when trying to start the engine. Corrosion on the battery terminals or rapid battery drain that won’t hold a charge are also common signs of battery failure.
Basic battery safety
Disconnect the negative cable first, then disconnect the positive cable. Install the new battery, connect the positive cable first, then reconnect the negative cable last. That reduces the chance of shorting a tool against the frame.
Official information note
Mistakes do happen. Battery specs can change by year, engine, market, terminal layout and installed options. Check the old battery label, operator manual, parts book and official yanmartractor.com website before ordering a replacement battery.
