The battery on a 1974 Massey Ferguson 165 is located in the same place as it is on most tractors – on the right side of the tractor, on the outside of the engine compartment. The battery is typically in a plastic or metal box. It is important to make sure the battery is securely mounted and not exposed to any potential damage from the elements. Additionally, it is important to make sure it is mounted in a location that leaves adequate space for other tractor components. If necessary, the battery may be relocated to a better location but the time to do so is during the installation process.
