CASE Construction Equipment introduces the new 521F wheel loader that meets federal Tier 4 Final emissions standards using Selective Catalytic Reduction (SCR) technology. The new machine delivers best-in-class 131 net peak horsepower with an FPT Tier 4 Final-certified engine that also provides quick throttle response and impressive torque. The 22,948-pound wheel loader has a bucket breakout force of 19,303 pounds with 2.3-cubic-yard bucket capacity.
The SCR 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.
