Glad to see someone bought that tractor. I have been watching it for a while on CL. I think its worth any where from 300 to 700 dollars. BTW welcome to MTF, nice find.
The blade would be worth another $100-$150.The wheel weights are plastic. The front wheels have hubs on them with dual bearings it looks like. Overall a decent tractor i think i even have the original blade for it and the pto.
