Have a bolen riding mower model 13AM762F765. While mowing front yard took a turn and mower stopped moving and I could smell belt burning. Pushed mower in back yard and replaced both rear belts with mtd belts. Just put it back together and same problem will not move forward or back. when I let up on the brake pedal I can smell the new belt slipping on the engine pulley. Would appreciate any help.

Does the input pulley on the transmission turn freely?

Jack up the back of the rider so both tires are off the ground. Rotate one tire and the opposite one should turn in the opposite direction. With the transmission in forward, rotate both tires in the same direction at the same time and the input pulley should turn.

If you can't rotate both tires, check and make sure the brake is not stuck, if that checks out then the problem most likely lies inside the differential/transmission.

jacked up lawnmower and tires rotate freely in neutral. in forward or reverse when i rotate the tire the other one turns in the opposite direction, I can not get them to rotate in the same direction unless there in neutral. Should I take the battery back out and see if I can rotate the pulley by hand?

Any of the part #'s I listed in my earlier post will work and the Oregon 45-257 bearing is around $4 each...:thumbsup:
