We have a MW 18/42 lawn tractor that we inherited many years ago. We ran it for a lot of years and stopped. It needs a new battery so it can go to our sons girlfriend, however we cannot find the correct battery . The battery has a label that is blank. It is approximately 8" long x 3" wide and 6 or 7" deep. The model number is a TMO-30000A / E 131H1. I have searched for the original number for the battery with no results. All it shows is batterys the style of 4 wheeler size and they will not fit the area it has for the battery. Thanks for any help you can offer.
