Representing one of the industry’s most popular size classes, the 521G provides extreme application versatility (three linkage options, multiple axle options, and broad attachment compatibility), best-in-class horsepower and breakout force, and powerful hydraulics, ensuring owners get the most out of each machine. Four power modes, excellent fuel efficiency, a new dynamic operator environment and proven engine and emissions technologies make these among the most productive and efficient loaders on the market.    

CASE was the first to employ SCR technology in heavy earthmoving equipment, making G Series wheel loaders the second generation of CASE wheel loaders to benefit from the fuel efficiency and cooler operating temperatures SCR offers compared to solutions with diesel particulate filters (DPFs). No regeneration, no recirculation of exhaust gasses, no temperature spikes to burn off particulate – all ensuring that a greater percentage of fuel use is put towards productive work. Matched with load-sensing hydraulics that ensure the machine is only working as hard as it needs to, as well as operating modes such as ECO that provide greater fuel efficiency, the 521G proves to be extremely fuel efficient.   

Automotive feel. Industrial performance.
The cab and operating environment of the G Series has been completely re-engineered to provide optimal operator performance, ergonomics and engagement with the controls and the surrounding jobsite. A new 8-inch LCD monitor provides the operator with simple control and greater insight over many loader functions and activities. The latest in electro-hydraulic controls, numerous seat and adjustability options, and an all-new membrane keypad further simplify comfort, operation and training. A new, one-piece rounded windshield and optimally placed mirrors, along with a rearview camera that feeds the new monitor, ensures full 360-degree visibility. And an entirely new HVAC system ensures operators stay comfortable throughout the year.      

CASE G Series loaders offer a number of service-related features that help extend service life of the machine, lower operating costs and improve overall serviceability. The CASE-exclusive mid-mounted cooling module ensures access to clean and cool ambient air to keep all operating components cool, while also limiting debris buildup and providing easy access for routine cleaning. This unique design allows the engine to be pushed lower and towards the rear of the machine, which improves balance and stability, but also places all routine service and maintenance items within easy reach of the ground. Factor in CASE ProCare, so owners can better and more accurately predict all owning and operating costs for the first three years of the machine while getting all parts and labor provided by CASE in partnership with the local dealer.
