Mustang Lawnman

I found this Mustang Lawnman lawn mower hidden in an old barn when I first moved into our new house. the engine was seized up but it was in great shape for its year. so I put some time into it and had my mechanic look at it and I got it back into running condition. I ddont know to much about it but its a cool old lawnmower. I still have the mower deck but that needs a new belt. But it runs and drives goin about 3mph!!!
