Product Description

Mobilfluid 426 is an extra high performance multipurpose tractor lubricant engineered to meet or exceed transmission and hydraulic fluid requirements. The advanced technology in Mobilfluid 426 is designed to optimise the performance of agricultural and commercial tractors operating in a wide range of environments and conditions. This next generation product combines select base oils and an advanced additive package to deliver the varied lubricant performance properties required by the drive trains of agricultural and construction equipment proven in severe duty applications. It is particularly well suited for reducing wet brake and Power Take-Off (PTO) chatter.

Features and Benefits

Next generation technology has vastly improved the performance capabilities of heavy-duty equipment in terms of load, speed, control, and reliability through innovative powertrain designs. These designs have changed and increased the requirements of powertrain fluids to deliver higher levels of performance and productivity while reducing operating costs. Friction control, wear protection, thermal stability, shear stability, rust and corrosion protection, and pumpability are features that must be optimally balanced to provide extended clutch life, maximum drawbar loading, and maintain operations on uneven terrain over a wide range of ambient temperatures. Mobilfluid 426 delivers exceptional performance in today’s power train transmissions, drive axles, clutches, PTOs and hydraulic systems. The key benefits include:

Features Advantages and Potential Benefits
Excellent frictional properties Optimal clutch and PTO performance
Excellent wet brake and PTO chatter control
Compatible with clutch materials and elastomers Long clutch life and reduced leakage
High viscosity index and improved shear stability Consistent operating response
Excellent protection against rust, corrosion, and yellow metal etching Protects equipment in wet or humid environments and prevents premature wear
Excellent low temperature properties Responsive operation and effective lubrication in cold weather applications
Strong anti-wear and extreme pressure properties Reduces wear, extends equipment life, and reduces maintenance costs
Good thermal and oxidation stability Reduces deposits, extends seal life, and increases service life of equipment and lubricant
Multipurpose capability Simplifies inventory and reduces misapplication problems
Good filterability Keeps systems clean and operating smoothly
