Massey Ferguson 420 Extra Battery Notes
Replacement note
For the Massey Ferguson 420, match the replacement battery to the captured spec: 12 V, Group 31, 800 CCA. Physical fit, terminal layout and hold-down fit still matter
Battery location
The Massey Ferguson 420 tractor uses a 12-volt battery
Battery replacement steps
Massey Ferguson tractors use a 12-volt battery; always disconnect the negative terminal first, then the positive, and reconnect positive first when installing the new battery. Clean terminals with a wire brush and baking soda solution to ensure a solid connection
Safe removal note
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 masseyferguson.com website before ordering a replacement battery.
