The battery on a 383 Massey Ferguson tractor is located in the battery compartment. To remove it, use a wrench to disconnect the negative and positive terminals, then remove the cable clamps that secure the battery. Next, use a battery puller or flathead screwdriver to loosen the battery hold-down bolts. In most cases, the battery can then be pulled out of the compartment. Make sure to reset the battery hold-down bolts and reattach the cables before replacing the new battery.
