I wouldn't scrap it Norm, I've seen 7 mm Kevlar that could be glued at a brake relining place ,not sure cost wise if worth doing.
There are usually people looking for half decent wheels for these Rover mowers .so you could remove the engine and sell the rest for $100. ,I had one that looked like it was left in the rain for a few decades but wheels were good so I sold that for $50.
