There are many engine-oriented tips for maintaining a tractor. As it is the most essential and delicate part, engine upkeep can be intimidating and expensive. However, tractor engines are not entirely unlike car engines. Quite a few maintenance items are the same and it can be a good habit to check the tractor engine at the same time as any other vehicle. Tractor engines will also need their fluids checked regularly and oil changed. They also benefit from regular air-filter changes and fresh gas if they have sat a while. It’s also a good idea to give a tractor a deep cleaning once in a while. Since they work in much rougher conditions than other machinery, they can get very clogged up and coated with muck.
