Thanks for sharing, I am always amazed at how long those old tractor last and still run strong, we have a late '80's era Craftsman with a 20 hp. Kohler engine, it's done our snow plowing for the last 8 years, it was well used when we bought it but it's given great service, it's starting to get tired, so my son picked up an '86 Bolens with the same Kohler 20hp. engine, it comes with a wider plow, mower deck, and harrow, all hydraulic.
He took it all apart and rebuilt the front end, put in new rear axles, hydraulic lines and wheels, brakes, tires, and starter, now he's got the engine out of it and assembling the parts to rebuild it, it wasn't supposed to be a total restoration, but that's the way it's going.
