521G

CASE 521G Wheel Loader

The CASE 521G delivers dependable breakout force, smooth hydraulic action and consistent output across long working days. The FPT engine runs clean without EGR and maintains strong torque under load, while the cooling cube layout keeps temperatures steady even in hot, dusty Australian conditions. This gives operators the confidence to push into piles, load trucks and handle bulk material without feeling the machine labour. Inside the cab, the eight inch display, seat mounted controls and quiet operating environment create a steady workspace for accurate machine control. Wide visibility and well placed joysticks allow operators to maintain strong awareness and smooth inputs while working close to trucks, stockpiles or site boundaries. The result is a compact loader that feels stable, responsive and easy to control in tight or open areas.

Product Features

The 521G offers Z Bar, XR and XT linkage options, allowing buyers to match the machine to specific tasks such as bulk handling, stockpiling or loading with extended reach. The load sensing hydraulic system keeps cycle times fast and consistent, while maintaining smooth control across the full lift and tilt range. Bucket options, tyre choices and factory quick couplers add further flexibility, letting owners set up the loader for farm duties, council yards, quarry work or construction sites. Daily operation is kept simple through smart layout and strong component access. With heavy duty axles, robust build quality and SiteWatch connectivity available, owners gain long term reliability and clear insight into machine performance and maintenance. Combined with low effort servicing and a comfortable operator station, the 521G supports high output while keeping running costs predictable and downtime minimal.

Powerful Output

The CASE 521G delivers the power and control needed for steady daily work across farms, council yards and construction sites. Its hydraulic system reacts smoothly to bucket and lift movements, giving operators confident control when pushing into piles or loading trucks. With multiple linkage choices and a compact footprint, the machine stays productive in tight spaces and open work areas alike.
