What do I do? Its wobbly and I can't remove the bolt because it has been spot welded I need my car I'm a singly mom w/disabled child

I have a troy-built lawn tractor I need to take the pulley off the shaft to take the belt out and I don't know how to get it off. It's the drive belt pulley.

A painter of mass M stands on a platform of mass m and pulls himself up by two ropes which hang over pulleys as shown beloew. He pulls each rope with force F and accelerates upward with a uniform acceleration a. Finds-- neglecting the fact that no one could do this for long

I need a diagram of the pulleys for a Yard Machine Lawn Tractor, lost my owner manuel and can not remember how belt goes on, Thank You:(
