Hello to all! I have a curious little find that I just picked up. I figured it to not be much, but it may be more than I thought. It is a small Montgomery Ward riding mower that looks to be in overall good condition. I dug it out of a friend's barn. I went looking for a manual and struck out on the model number - TMO-33906A. I learned enough to know it is MTD built. I'm guessing it was built in the early 80's, but I'm not sure. It has an 11hp Briggs & Stratton with a 5 speed tranny and a 38 inch deck. Curious to see that it uses a motorcycle battery. Could it be changed over to use a regular lawn & garden battery? Looking for any information I can find. Here are a couple pictures.
