Case Equipment introduced the 1850K and 1650K crawler dozers to its K Series. The Case 1850K crawler dozer provides up to 205 hp, 671 lb-ft of torque and 126 in of track on ground. The Case 1650K delivers 145 hp, 428 lb-ft of torque and 118 in of track on ground. Blade capacities range from 4.1 yd3 on the 1650K to 7.4 yd3 on the 1850K.

K Series dozers include a hydrostatic PowerSteer system, which features single-lever control of direction and steering. A fuel-efficient six-cylinder Cummins engine powers a three-speed, torque-converter transmission. The torque converter automatically matches speed to load requirements, lessening demand on the engine and saving fuel. Torque multiplication provides maximum drawbar pull of up to 48,000 lb-ft on the 1650K and 64,100 lb-ft on the 1850K. A tapered hood design helps increase visibility from the cab, especially to the edge of the blade. The cab is rubber-isolation mounted for a quiet, comfortable ride. Fingertip low-effort servo hydraulic controls and extra-long track undercarriages ensure precision grading ability.

Case K Series crawler dozers are available in a wide variety of track and blade configurations to handle varying site conditions. Both models come in an extra-long-track (XLT) configuration for unsurpassed grading ability and traction, and a low-ground-pressure (LGP) configuration that provides greater flotation and stability on slopes. The 1850K also comes in a long-track (LT) configuration for good blade control and visibility.

Caterpillar equipment offers nine different base models of crawler tractors for contractors doing site preparation work. The machines range in size from the 70-hp, 16,000-lb D3G XL to the 410-hp, 106,000-lb D9T. Several of the versatile medium-sized tractors, such as the D6R Series III, feature the Caterpillar exclusive SystemOne Undercarriage, which offers extended life and lower operating costs. A variety of undercarriage configurations for each of the tractors allow each machine to be matched to the contractor’s needs. The D8T and D9T also feature CAT engines with ACERT technology for compliance with emissions regulations while creating responsive power and maintaining reliable, durable performance.

New Dressta crawler dozers feature increased drawbar pull, larger blades and improved operator controls. A lefthand joystick on all TD-15Ms, TD-25Ms and TD-40Es utilizes twin rocker switches and push buttons allowing selection of Hi- or Lo-geared track speeds and transmission gears. By simply using a thumb and moving the joystick, an operator has complete control over the machine’s ground speeds and direction, improving operation efficiency. Dressta crawler dozer specifications include: operating weights from 16,200 to 146,915 lbs; net engine hp from 74 to 520; blade capacities (cy) from 1.81 to 52.00; and blade widths from 8′7″ to 22′6″.

John Deere equipment J Series dozers feature a smooth, full-featured hydrostatic drivetrain, integral power management system, Deere’s exclusive Auto-Trac system to keep the machine tracking straight, and the DuraTrax undercarriage for a long life and smooth ride. Optional Extended Life SC-2 bushings are available on 450J-850J models to further lower undercarriage operating costs. Improved operator’s station ergonomics and visibility help boost productivity.

Komatsu America Corporation offers the D65 series crawler dozers. The D65EX-15, D65PX-15 and D65WX-15 feature a powerful Komatsu equipment for sale SAA6D114E-5 turbocharged diesel engine, which provides a maximum net output of 205 hp. The engine is EPA Tier 3 and EU Stage 3A emission regulation-certified and has horsepower and torque output that meets or exceeds previous Tier 2 engines. The dozer equipment are equipped with the latest Komtrax technology to send machine operating information to a secure website utilizing wireless technology.
