Fluid & Oil Types
Engine oil - The ideal weight of engine oil depends on the climate where you live. In colder areas (northern states) a 10W30 is typically preferred (it is a little thinner in the cold and will allow easier starting in the winter). In warmer areas (southern states) a 15W40 is usually preferred (it holds up better in the summer heat). Just look on the jug of oil and compare the recommended temperatures to the average temperature where you live. Either of the above weights will work fine in most areas of the USA. Just be sure the oil is rated for a Diesel engine. Shell Rotella is a good oil but any brand of diesel engine oil will work.
Transmission/Hydraulic reservoir - sold under many names like -JD303*, J10A, J14A, J20A,B,C,D, J27A or a host of other brands and numbers.
*An important note about '303' oil:
The 'JD303' oil was developed by John Deere in the 1960's. Deere discontinued it in 1974. The testing standards for that oil are no longer available so the claim 'meets 303 standards' is not able to be confirmed or tested. Some oil manufacturers may be substituting an under-performing oil in its place.
