CASE 1850K Dozer

Serious muscle and efficiency is delivered from the six-cylinder, Case Family 4 Tier III-certified engine. Maximum pushing power is made possible by the torque converter Power Shift transmission and differential steering. And for optimum control and breakout force, the high-performance blade hydraulics feature large pump cylinders, while nearly any soil condition can be met with the adjustable blade pitch on Straight and Semi-U blades. Three track options provide maximum versatility and include Extra Long Track (XLT),  Wide Track (WT) and Low Ground Pressure (LGP).

Meet current environmental standards and consume less fuel with Tier III-certified engines.

Noise and vibration are reduced with the isolation-mounted operator platform. And for convenient ergonomic operation, the steering wheel is infinitely adjustable.

Rocks, dirt and debris are kept out of the undercarriage due to the sloping track frame. And daily maintenance is simple with the tilt-over operator platform for convenient access to the drivetrain, along with swing-out service panels and spin-on filters.
