Yanmar AF-30 Extra Battery Notes
Battery location
The battery on the Yanmar AF-30 tractor is located under the hood, secured by a hold-down assembly near the engine.
Battery replacement steps
To replace the battery on a Yanmar tractor, first park the tractor safely and securely, then shut off the engine. Next, remove the negative cable first, followed by the positive cable, and then take out the battery; installation is the reverse order, connecting the positive cable first.
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.
