Serious productivity, maximum efficiency.

Handling shot rock just got a shot in the arm at your quarry. The hybrid-electric 944K helps maximize productivity and efficiency at a lower daily operating cost. Everyone knows hybrid-electric drives burn less fuel. But they're highly productive, too, delivering quick, smooth, and responsive hydraulics; fast ramp-climbing capability; and strong pushing power. Plus control of automatic traction and rimpull helps eliminate wheel spin and tire wear, further reducing daily operating costs. The 944K Hybrid Loader boasts the biggest cab, quickest boom-raise time, and fastest cycle times in its class. Outstanding visibility with LED lighting options combined with smooth, responsive hydraulics help you work harder with less effort.
