621G

CASE 621G Wheel Loader

The CASE 621G delivers strong, dependable performance for busy work sites that need steady cycle times and accurate bucket control. Its FPT engine provides smooth torque through the full rev range, allowing operators to push into dense stockpiles and handle heavy loads without strain. The cooling cube layout keeps airflow consistent, which helps the machine stay cool and reliable during long hours in hot, dusty Australian conditions. The auto shift transmission matches gears cleanly to the load, keeping the machine in the right power band as ground conditions and travel speeds change. Combined with responsive hydraulics and predictable steering feel, the 621G gives operators the confidence to load, lift and carry with accuracy on tight sites, wide yards or uneven surfaces.

Product Features

With Z Bar, XR and XT linkage choices, the 621G can be tailored to bulk handling, high lift work or general purpose loading across quarries, farms, council depots and construction sites. The load sensing hydraulic system supports quick bucket movements and smooth control, helping crews maintain a fast, consistent work rhythm. Operators also benefit from a wide range of bucket and tyre options, plus factory quick couplers that make attachment swaps simple and efficient. Inside the cab, the eight inch display, quiet operating environment and seat mounted controls create a comfortable and clear workspace. Visibility around the machine is strong, which improves safety and helps the operator maintain awareness around trucks, stockpiles and site activity. Combined with easy daily access and a robust build, the 621G gives owners a productive, low stress machine that works reliably through long shifts.

Strong Daily Performance

The CASE 621G delivers steady breakout force and smooth control that helps operators stay productive through constant load and carry work. Its hydraulic response supports confident bucket action, and the machine holds its pace well across mixed ground, making it reliable for long shifts in civil, quarry, farm or council operations.
