Zetor 4340 Extra Battery Notes
Battery replacement steps
To replace the battery on a Zetor 4340 tractor, first disconnect the negative terminal followed by the positive terminal, then remove the old battery. After that, place the new battery in the compartment, connect the positive terminal first, and then the negative terminal.
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 zetor.com website before ordering a replacement battery.
