First tractor ever. First thing I did was buy the manual from Jensales so there are no mysteries when a maintenance issue arises. I learned that water will leak into the transmission/hydraulic system and freeze up the components.
Built a custom backhoe and dug a 5'x 200' trench and it only burned about $10 in fuel. Engine starts all the time, great unit, keeps your arms in shape when working with the loader full. Maintain the fuel system (filter and injector pump) and lots of grease and oil, the cheapest maintenance.
