What is Tractor Hydraulic Fluid?
Did you know that hydraulic fluids for tractors are NOT the same as other hydraulic oils? Please do not use that extra pail of hydraulic fluid or "303" fluid you have in the shop in your tractor. Tractor hydraulic fluids are specifically designed to fulfill multiple functions such as transmissions, differentials, final drives, hydraulics, PTO's, power steering, and wet brakes.
Tractor hydraulic fluids have several different names, but they all mean the same thing. You may hear "torque converter fluid," "UTTO," which means "universal tractor transmission oils," "tractor hydraulic oil," "UDT," which means "universal dynamic tractor oil," as well as a few others.
Many different companies make universal tractor hydraulic fluids that will work for most farm and industrial tractors. Always check your owner's manual or call the dealer for the correct specification. You can also check the THF specifications to see if your tractor is listed as compatible.
Also, did you know that the dealer you bought your tractor from cannot require you to use their products/service to keep your warranty coverage unless they provide it free of charge? You can read more about that by clicking here.
THF comes in different formulations. Some of the choices offered by Schaeffer Manufacturing include biodegradable for environmentally sensitive areas, low-viscosity for colder/winter applications, conventional and semi-synthetic.
Using any fluid labeled "303" can damage your equipment! Before 1974 John Deere manufactured and sold a THF called "JD 303". John Deere discontinued production, and the 303 designation has been obsolete for over 40 years. Some lubricant manufacturers and sellers have been producing and selling THF as "303" in bright yellow buckets. We have all seen them stacked up in a prominent place at the various farm and manufacturing supply stores at a great price. This 303 THF usually fails to meet any manufacturer's specifications, and it is made with inferior components and is not appropriate for use as a tractor hydraulic fluid. These mislabeled 303 fluids can cause harm, increased wear, and damage to your equipment. Several states bring ongoing pending lawsuits against these product manufacturers and sellers. That $29 pail is a lousy investment.
We have found the following quote to be right on the money (so to speak) and feel it's worth repeating!
"It's unwise to pay too much, but it's worse to pay too little. When you pay too much, you lose a little money - that's all. When you pay too little, you sometimes lose everything because the thing you bought was incapable of doing the thing it was bought to do. The common law of business balance prohibits paying a little and getting a lot - it can't be done. If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that, you will have enough to pay for something better." - John Ruskin 1819-1900
No matter what color/brand your tractor is, purchasing and using a high-quality THF will provide you with many benefits. Some of these are reduced operating temperatures, reduced system wear, and tear, increased operating efficiency, and potentially longer service intervals.
