New Wheel Loader from Case

The new Tier 4 final 521F wheel loader from Case is a high performance machine that can move up to 212 tons of material per hour while using 12 percent less fuel, the company reports. The wheel loader uses Selective Catalytic Reduction (SCR) technology, delivers 131 net peak horsepower, weighs 22,948-pounds with a bucket breakout force of 19,303 pounds and 2.3-cubic-yard bucket capacity. 

case 521`f wheel loaderSCR technology allows the machine to handle inconsistent engine loads while running at peak performance without compromising power. This is accomplished with a faster throttle response and acceleration, all while maintaining lower exhaust temperatures and improving fuel efficiency. With SCR technology the wheel loader features 10 percent greater fuel economy over wheel loaders featuring CEGR-DPF solutions.

It achieves additional fuel savings with a standard auto-idle feature and standard auto shutdown. The SCR-only approach found on the new 521F also contributes to machine uptime by eliminating the need for manual diesel particulate filter (DPF) regeneration and the associated downtime that can occur with wheel loaders that use cooled exhaust gas recirculation (CEGR) technology. There is no need for recirculation equipment or a DPF and SCR results in extended time between service intervals.

The 521F features the mid-mounted cooling system, configured like a cube with all coolers facing fresh and cool ambient air. This improves the effectiveness and efficiency of the cooling system and makes it easier to clean. 

The 521F incorporates powerful and quick hydraulics in addition to other features, including:

  • Standard limited-slip axles
  • Standard Z-bar linkage for large operating loads; XR linkage for extended reach and dump clearance; and the tool-carrier XT linkage for utility, visibility and parallel lift.
  • Buckets available with the 521F feature the optional SmartFit bucket tooth system. These heavy-duty self-sharpening teeth combine strength and an unmatched ease of installation due to a hammerless fastener system with reusable locking pins.
  • An expanded selection of attachments.
