Radial-Lift Boom

The radial-lift boom offers more reach at mid-range lift heights, good for digging, grading, and backfilling. It provides powerful digging performance at a competitive price.

The low center of gravity and superior balance provide exceptional agility and stability on slopes.

Engine

Final Tier 4 (FT4)/EU Stage IV diesel engine packs plenty of power and torque.

Large coolers provide increased heat rejection for superior performance in severe, high-load conditions. Engine-mounted, belt-driven cooling fan delivers efficient, reliable performance.

Mobility

With weights from only 5,995 to 6,315 lb., these compacts are easy to trailer behind a pickup truck.

Without a bucket, the 312GR slims down to 1600 mm (62.9 in.) to fit through narrow openings.

Cab & Controls

Larger entryways with swing-out doors make it easier to get in, get comfortable, and get on with it. Inside, there’s more productivity-enhancing foot- and legroom.

Low-effort foot pedals are standard on skid steers; manual hand controls are available.

Uptime

Generous tank capacity and fuel-efficient diesels enable day-long operation, letting you accomplish more between fill-ups.

Rear door enables easy, ground-level access to daily service checkpoints and cooling system components.
