CASE Construction’s 521F wheel loader features a FPT Tier 4 Final-certified engine that delivers a 131-hp rating. The 22,948-lb. wheel loader has a bucket breakout force of 19,303 lbs. with 2.3-cubic-yard bucket capacity.
The wheel loader’s selective catalytic reduction technology allows the machine to handle inconsistent engine loads while running at peak performance. This is accomplished with a faster throttle response and acceleration, all while maintaining lower exhaust temperatures and improving fuel efficiency. Fuel savings are achieved with a standard auto-idle feature that helps minimize excessive fuel burn during operator inactivity by further lowering engine RPM.
The 521F wheel loader incorporates powerful and quick hydraulics in addition to standard limited-slip axles, a Z-bar linkage for large operating loads, a wide variety of tires, and an expanded selection of attachments.
It includes a joystick steering option and an Advanced Instrument Cluster with four selectable power modes for precise control. It also features the CASE Quiet Cab, the largest cab in the industry, which offers a dual air filtration system, optional heated air-ride seat, and insulated cab mounts to provide a clean, quiet operating environment.
The 521F features ground-level fluid gauges and a tilt-up rear hood that provides complete engine access. The lower profile also allows for a sloped rear hood that further improves visibility to the back of the machine.
