651G

CASE 651G Wheel Loader

The CASE 651G delivers a strong mix of power, smooth control and reliable traction for busy worksites that need steady cycle times. Its FPT engine produces consistent torque that helps the machine push into heavy piles, lift dense loads and maintain pace across long runs. The cooling cube layout supports stable airflow in hot Aussie conditions, keeping operating temperatures under control during long hours. The transmission delivers clean gear shifts and keeps the loader in the right range as ground conditions change. Combined with responsive hydraulics and predictable steering, the CASE 651G gives operators a confident feel when lifting, carrying or placing material, whether on construction sites, quarries or large agricultural operations.

Product Features

The CASE 651G can be set up for a wide range of tasks thanks to its linkage options, bucket choices and factory fit couplers. The load sensing hydraulic system maintains strong flow while delivering smooth bucket control, helping crews complete repeated cycles with accuracy and speed. Tyre packages and attachment combinations also let owners tailor the machine for bulk handling, stockpiling or general site duties. Inside the cab, visibility is wide and unobstructed, supported by an eight inch display, quiet interior and well placed controls that keep operation simple and comfortable. Daily servicing is made straightforward with ground level access and a tidy component layout. The result is a loader that handles demanding workloads while keeping running costs predictable and downtime minimal.

Strong Output

The CASE 651G delivers steady power and fast bucket response, helping operators maintain strong output during busy load and carry work. Its hydraulic performance supports clean filling and smooth lift action, making the machine dependable for long shifts in quarry, civil and agricultural environments.
