Bought tractor for mowing, light plowing, and light work around property. Original owner (my uncle) kept it in a shed. Another user used it for a few years after my uncle passed, and didn't perform maintenance. When I purchased it from my aunt, I changed all fluids and filters, except for the fuel filter. At first it leaked fluid from the right rear axle, but finally stopped. I also had to replace the battery.
The only problem I have had with it is poor starting when it got cold. It finally started to hard start during warm weather, so I had the starter checked, even though it got the engine speed to 2-225 RPM. It seemed to me that it was pulling too many amps as the battery voltage dropped quickly, and the cable ends got hot. Pulled and disassembled the starter and it was unbelievably gunked up with fine grass and oily residue. I had it rebuilt, and at the same time I checked/replaced the fuel filter, which should have been done a lot earlier, as it was nasty. Could not shut off the petcock while replacing the filter, and have to replace it also. As soon as this has been completed, I will post the results.
Other than that, I have been happy with the tractor. I did run into a tree while mowing some property and had to realign front end. After removing the drag links and straightening them, I bought taps and dies to clean and dress the threads, which made them a lot easier to adjust. Also bought new tires a couple of years ago.
