I've had this tractor for a few years now. We use it around the farm for odd jobs, like grading our driveway (.75 mile minimum maintenance), brush hogging, etc. It is very easy to work on and parts are cheap.
We converted ours to 12V and added an electronic ignition to get rid of the points and provide better starting. I recently did an in-frame overhaul to correct some low compression. It is not bad considering that it was last overhauled in 1966 from the previous owner.
Mine has an over/under drive auxiliary transmission (Hupp) that was installed by the dealer when it was new, which is a great addition to make up for lack of gears.
The 1-1/8 inch power take-off shaft really needs an adapter/override clutch to brush hog with. You might end up going through a fence otherwise. Filled tires and chains are handy when we need multiple tractors pushing snow.
Other than that, it is a good little utility tractor for the farm. We probably put 20-25 hours on it a month.
