The 411 on 303 Tractor Hydraulic Fluids

Did you know that tractor hydraulic fluids (THF) labeled with the “303” designation have been obsolete since 1974?

Though the “303” designation was discontinued more than 40 years ago, “303 THF” is still on the market and oftentimes promoted under misleading claims.

In a report from the Petroleum Quality Institute of America, 91% of examined samples of 303 PQIA failed to meet the viscosity requirements for the current J20C specification, and J20A, which has been obsolete since 1989. (See the full report here.)

The use of fluids that do not meet the current standards can lead to shortened equipment life, more downtime, application failure, all which can lead to an overall higher cost of ownership.

The good news is that there are better products available such as Shell Spirax® S4 TXM (pictured), a high-performance, universal tractor transmission oil designed to protect heavy-duty off-road transmissions from wear and corrosion.

So, the question is: do you know what you’re putting in your equipment?
