Case placed its 521F wheel loader under the spotlight at its booth at AGG1 here in San Antonio. Officially introduced in early February, Case discussed with Aggregates Manager some of the machine’s benefits specifically for this industry.
Case marketing manager Rob Marringa detailed the wheel loader’s three available arm options: Z-bar, extended reach and tool-carrier. It also offers four operating modes and auto-idle. Be sure to check out the video below to hear Rob talk about each arm option in detail along with all the other features of the 512F.

The 521F, the newest in Case’s F-series, offers 12 percent increased fuel efficiency over the previous model and 10 percent better load capacity. The machine has a lift capacity of 19,596 pounds, a bucket breakout force of 16,735 pounds, an operating capacity of 22,856 pounds, and a hinge pin height of 11 feet, 10 inches.
The wheel loader, powered by a 4.5-liter Tier 4 interim-compliant Case engine, features a 3-yard bucket and produces about 130 horsepower. Other features include a 70.8 decibel rating, an air filtration system, joystick steering and axles with auto-locking front and open rear differentials that can move approximately 212 tons of material per hour.
Case added selective catalytic reduction (SCR) to the 521F to lower temperatures. SCR improves fuel efficiency by about 14 percent over the previous model.
The cab includes several features to promote operator visibility such as improved lighting for nighttime operations, heated mirrors and a rearview camera option.
