Got to have some fun yesterday. One of my neighbors (the one who bought a new green LAWN tractor this summer) had his dad's 1953 Ford "Golden Jubilee" tractor in his shed. It hadn't been started for many years. I hooked a chain on the 125 and the drawbar of the Ford. After propping up the four foot deep shelf which had settled onto the tractor hood, it took several yanks to get the Ford to move. The front and calcium-filled rear tires had settled fairly well. The floor probably had four good dips in it, too. Naturally, there was only about ten feet from the back of the Ford to the two-bottom plow and other assorted heavy immobile stuff, so I could only go straight for a few feet, then had to pull at an angle with a longer chain. The doorway is about an inch and a half wider than the tractor, so Charlie steered and braked when it wanted to roll back forward.
The 125 had enough power, but it couldn't keep traction, so I moved a little, spun, backed up, and pulled again. The only weight on the 125 was me (185 pounds) and the mower deck. I would have used the 147, but I didn't like the idea of pulling that much with the tiller gearbox still mounted on it. Once it came off the "flat spot" of the tires, it moved pretty well, and pulled straight out.
He charged the battery, got enough fuel in the strainer to swell the gasket and stop the leaking, and got it running a couple hours after we got it outside. The hydraulics even worked. Sounded pretty good, except for the occasional miss, like it had a valve sticking once in a while.
He never even mentioned the possibility of using his green machine to move it.
