- The John Deere 650 is distributed by John Deere and manufactured by Yanmar in Japan with a Yanmar T280 engine. The Yanmar T280 engine is a 2-cylinder diesel engine with liquid cooling. This particular model has 2,600 rpm with 12 starter volts. It's available in 4x2 or 4x4, manual or power steering.
- Diesel engines need different care than gasoline engines. Diesel engines generally create greater internal pressure and heat, therefore oil is used more in diesel engines for cooling the engine than with gasoline. They are also more susceptible to engine problems caused by poor lubrication and dirt. Improper oil use and care can be detrimental to your tractor, causing serious engine damage, overheating and thermal distortion.
- There are several oil types, and within these types are various classifications. The two most common types are designated for diesel (compression engines) and gasoline engines (spark engines). Each type has a API (American Petroleum Institute) rating. The ratings will signify the type of oil and class. The first letter represents the type "C" for diesel compression engines and "S" for gasoline spark engines. The second letter represents the class or grade.
- To properly maintain and care for your Yanmar diesel engine, it is recommended that you use an oil with a classification of CE, CF, CG or higher.
