Also, verify if the terminals belong facing the front of the tractor or facing the driver's seat. Then determine which side of the battery that you want the positive and negative terminals on. Lastly, before you buy a battery, check to make sure that the red battery is the positive battery cable and the black is negative. There have been way too many posts where people hook up the battery incorrectly and do a lot of damage to the electrical system. If you purchased the tractor new, then you are relatively safe that the battery cable locations and hook-up are correct. If it is used, check everything first. A bright LED flashlight can help you to not make expensive mistakes.
