<p>550K crawler dozer</p>

John Deere's 550K crawler dozer was added to its K-Series machines and build off the popular 850K that launched in 2011. Other new K-Series machines are the 650K, and 700K, and 750K.

A John Deere PowerTech 4.5L (550K, 650K) IT4 diesel engine provides an increase in horsepower from the previous J-Series, along with increases in overall tractor weight, resulting in more productive machines. The 550K provides 85 hp.

The K-Series uses cooled EGR technology with exhaust filters, which meet 2012 EPA emissions regulations. The engine's diesel particulate filters are cleaned automatically during routine operation, eliminating the need to idle down for maintenance and increasing overall machine productivity. In addition, filter access is easy for servicing purposes.

The John Deere IT4 engine also offers operation on slopes up to 45 degrees while maintaining adequate oil flow to machine systems. A hydraulically driven cool-on-demand fan operates only as needed, decreases cab and bystander noise levels, and cuts fuel consumption. A reversing feature is optional for the 550K.

The four new K-Series crawler models come equipped with hydrostatic transmissions. These transmissions provide customers speed control, power management, live power turns, counter rotation while staying in gear, and dynamic braking. In addition, Total Machine Control allows customized machine response that can be tailored to meet the needs of individual operators.

Inside the cab, operators will find increased comfort thanks to quieter operation, larger access doors, and a standard air suspension seat. Sound dampening in the cab reduces noise levels up to a 50-percent on the 550K. Best-in-class visibility to the blade and jobsite is provided via ample glass and well-positioned in-cab components. The models also feature a sealed switch model (SSM) with keyless start and a coded-security start feature, a 12-volt electrical accessory outlet and an integrated grade control monitor.

Onboard diagnostics include a standard display monitor that provides real time values for every temperature, pressure, and speed sensor on the machine. The crawler dozers constantly monitor transmission temperature to avoid damage to the hydrostat system. If the transmission temperature is too cold or too hot, the associated light on the monitor will illuminate.

The JDLink Ultimate system continuously collects and transmits machine data for machine management via mobile phone technology. The system enables the preventive maintenance and remote diagnostics of crawler dozers, as well as the tracking of machines working on multiple jobsites.

DUI or Driving Under the Influence (sometimes called DWI or Driving While Intoxicated) is a criminal offense in most states (most countries, actually). The substance can be alcohol or drugs, which is why it's not merely called "drunk driving" anymore.
