Shell Spirax S4 TXM
Shell Spirax S4 TXM is a premium universal tractor transmission oil (UTTO) developed to deliver reliable lubrication and performance in modern agricultural and off-road equipment. Formulated with high-quality base oils and advanced additive technology, the lubricant is designed for use in transmissions, hydraulic systems, oil-immersed brakes and other ancillary components fitted to agricultural tractors and construction equipment. Its balanced formulation helps ensure consistent equipment performance while supporting long service life for critical drivetrain and hydraulic components.
One of the key advantages of Shell Spirax S4 TXM is its enhanced protection for mechanical components. The advanced additive system provides excellent anti-wear, anti-corrosion, anti-foam and oxidation resistance properties. These features help protect gears, bearings and hydraulic pumps from wear and damage while maintaining lubricant stability over extended operating periods. This protection helps increase equipment reliability and minimise downtime, supporting efficient operation in demanding agricultural environments.
Shell Spirax S4 TXM also delivers excellent operator comfort through smooth transmission and hydraulic performance. The formulation offers very good low-temperature fluidity, which allows the oil to circulate quickly during cold starts. This ensures responsive hydraulic system performance and smooth gear engagement from start-up through to full operating temperatures. These characteristics help improve machine control and ensure consistent performance across varying operating conditions.
Another important benefit of Shell Spirax S4 TXM is its optimised performance in oil-immersed brake systems. The lubricant contains specialised friction-modifying additives that help ensure smooth and noise-free operation of wet brakes. By controlling friction characteristics within the braking system, the oil helps reduce brake chatter and vibration while maintaining effective braking performance in tractors and off-highway equipment.
Shell Spirax S4 TXM has been widely tested and approved by major agricultural equipment manufacturers and is suitable for use in most modern tractors and off-road machinery. The lubricant is recommended for use in agricultural tractor transmissions, hydraulic systems and wet brake systems as well as in ancillary equipment operating with shared transmission and hydraulic oil systems. It is particularly suited for equipment from manufacturers such as John Deere, Massey Ferguson, CNH and ZF.
The product meets key industry and OEM specifications including API GL-4, John Deere JDM J20C, Massey Ferguson M1145, Case New Holland MAT 3525 and Volvo WB 101. It also meets ZF TE-ML 03E, 03L, 05F, 06D, 06K, 06M, 06N, 06R, 17E and 21F performance requirements and is suitable for applications requiring Allison C-4 type fluids. Physical characteristics include a kinematic viscosity of approximately 60 mm²/s at 40°C and 9.4 mm²/s at 100°C with a viscosity index of approximately 138. The oil has a density of approximately 882 kg/m³ at 15°C, a flash point of approximately 220°C and a pour point of approximately –42°C, supporting reliable lubrication performance across a wide range of operating conditions.
