The new Caterpillar 904H was released on September by te company. The loader features a new engine, new axles, articulated steering, two-speed hydrostatic drive, powerful Z-bar loader linkage, universal coupler (compatible with skid-steer-loader work tools), new operator’s station and fresh styling—including a new hood, counterweight and non-metallic fenders, but more important still, is that this machine is designed for reduced exhaust emissions, the 904H uses the turbocharged MHI S4Q2 diesel engine, which meets Interim Tier 4 regulations.

The new engine powers a closed loop, single path hydrostatic transmission that works in combination with a frame mounted gear box and mechanical axles. The newly designed axles provide more ground clearance and can be equipped with optional locking differentials to help the 904H power through adverse ground conditions.
Also the standard auxiliary hydraulic system, with a rated flow of 22 gpm (83 L/min) at a relief pressure of 3,000 psi (207 bar), generates ample hydraulic horsepower for efficiently operating powered work tools.

Available with either cab or canopy, the new 904H operator station is designed for comfort and convenience—featuring ample space, enhanced visibility and redesigned controls. Optional performance features, including ride control and creeper control, allow more precise operation of the machine. The Routine maintenance for the 904H is simplified with a tilt-up engine enclosure for easy access to service points, centralized lubrication, hinged oil cooler and standard oil sampling valves for quickly sampling engine and drive-train fluids.
