Case Construction Equipment’s 1850K Series 3 crawler dozer is Tier III compliant and features more horsepower, along with the added convenience and ease of operation of electro hydraulic controls for both the power train and hydraulics.

The power train includes a net 184-hp (137 kW) Case Family IV engine on the LT and XLT configuration and a net 199-hp (148 kW) Case Family IV engine on the LGP configuration that boasts six cylinders in a four-valve, 6.7-L package featuring electronic fuel injection.

The Case 1850K crawler dozer provides up to 702 ft./lbs. (3,122 N) of torque and 126 in. (320 cm) of track on ground.

The 1850K also features electro hydraulic controls, giving the operator fingertip control with a single joystick lever.

“Now you can operate the blade with one control instead of two, meaning there’s a lot less effort required,” said Jim Hughes, Case brand marketing manager. “It feels more like the joystick on a video game.”

Case continues to offer its hydraulic variable PowerSteer, featuring differential steering with a three-speed power shift transmission to deliver maximum power to both tracks.

“PowerSteer lets you push a full load through a turn with no problems and delivers substantial productivity from the machine, improving your bottom line,” Hughes said.

Matching the undercarriage to the job is easy with options that include long track, extra-long track and low-ground pressure, with 75 and 82-in. (190 and 208 cm) gauge oscillation track on the ground. The LT version puts 106 in. (269 cm) of track on the ground, while the XLT and LGP versions put 126 in. (320 cm) on the ground.

“The oscillating undercarriage allows the tracks to follow the terrain, no matter what the conditions, so you get outstanding traction, stability, and blade control in all kinds of applications,” Hughes said.

The undercarriage features segmented sprockets to simplify the replacement of individual segments and reduce equipment downtime and costs.

Blade configurations include a six-way power-angle tilt for increased flexibility. The semi-U blade configuration delivers maximum capacity and an outside push beam for dozing in difficult ground conditions. The straight power-tilt blade on the 1850K LGP provides balance in soft conditions. An equistatic compensator on the 1850K reduces stress on the blade and push beam for added durability and machine life, according to the manufacturer.

Case continues to offer on-board diagnostics, Auto Shift and Auto Load functions along with a tilt cab and ROPS.
