Fuel-Efficient 521F Wheel Loader
Case Construction Equipment is introducing the new Case 521F wheel loader, offering producers a 12% increase in fuel efficiency over the previous E Series model, while delivering faster acceleration and quicker cycle times. The machine is available in standard Z-bar, extended reach, and tool-carrier models.
Case chose selective catalytic reduction (SCR) technology for the 521F to meet Tier 4i emissions standards based on the machine’s application tasks and power demands. “SCR was the obvious choice for the 521F because a wheel loader’s tasks are more variable, including things like cleaning stalls and corrals, transferring and loading feed into feed mixers, and pushing manure. This creates inconsistent engine loads and power demands,” said Rob Marringa with Case. “Rather than compromise power, we let the engine do what it does best – run at peak performance – and then use an after-treatment for emissions.”
The benefits of SCR technology are greater efficiency and reduced downtime because there’s no heightened fuel burn or diesel particulate filter (DPF) regeneration. The new wheel loader runs on a 4.5-liter Tier 4i Case engine that delivers up to 131 gross hp.
The 521F offers optional heavy-duty axles with auto-locking front and open rear differentials. On a 50-meter loading and dumping cycle, Case estimates the 521F wheel loader can make up to 56 cycles per hour, moving up to 212 tons of material per hour.
The new advanced instrument cluster (AIC) on the 521F has four operating modes, allowing operators and service technicians full visibility and control of basic job functions, such as diesel exhaust fluid (DEF) level and fuel efficiency, as well as protective controls that can help eliminate costly repairs.
Thanks to the Case coupler system that pulls attachments closer to the machine, the wheel loader can handle heavier and larger buckets. The coupler is compatible with JRB and ACS attachments as well as Case SmartFit bucket tooth systems. The standard model delivers 19,596 pounds of lift capacity and 16,735 pounds of bucket breakout force. Base price for the 521F starts at $175,800.
