Did you find your manuals?
We had that very tractor years ago on the farm. Built tough like you would not believe. We rebuilt the engine. The air cleaner had a leak in it that let dust in. The only real problem we ever had was with that 12/24 volt switch. Half the time we gave it a short pull to start. It always started on the first turn, so that was no problem. This was in Alberta, so no hills to roll down. Of course the manual went with the tractor. If I recall they had a great section on building stands for splitting and for the engine. Very economical to run. Would still be today. It never overheated. It was a bit noisy though. While breaking with it, if you hit a big stump, it would just lift the front end right off the ground.
