i have a 1976 case 1175 tractor. its 122 hp. i built a dozer blade for it 7'6" wide and 3' tall. it'll uproot 12" pine trees. i'm using it to clear my 23 acres. leaves caught on fire on the exhuast and top of the motor. before it could be put out it spread through various oil leaks on its way back to the fuel tank. where it procceeded to ignite the rear tires and burn to the ground. now heres the question. i believe the motor to be in good condition, but everything on the rear half of the tractor that was rubber will have to be replaced for sure. i bought the trac for 5000. i replaced the exhuast system and the turbo, which should all still be good. i'm thinking about rebuilding? what would ya'll do?
