I have a 1996 MTD riding lawn mower that is in pretty rough shape from sitting outside and not used for 4 years. I've got it all cleaned up and tuned-up but still have a problem with the back tires. They seem as if they are stuck in gear or the breaks are locked up. I've tried pushing them, turning them by hand and still nothing. When you press the break/clutch in it does engage the brakes and the gear shifter seems to work and go between forward, neutral, and reverse but still the tires are stuck.
Any ideas.
