Final Tier 4-compliant machines feature an updated electro-hydraulic (EH) control system.
The John Deere 550K, 650K and 700K Crawler Dozers not only meet Final Tier 4 emissions standards, but also incorporate value-enhancing features such as Eco mode and an updated electro-hydraulic (EH) control system. The K-Series dozers provide contractors a Final Tier 4 product that affords higher productivity, increased uptime and lower daily operating costs in earth moving and grading applications.
The 550K and 650K incorporate a PowerTech 4.5L Final Tier 4 diesel engine with 92 hp and 104 hp respectively. The 700K boasts a PowerTech 6.8L Final Tier 4 diesel engine with 130 hp, a five horsepower increase over its IT4 predecessor. All three models incorporate John Deere’s new Eco Mode feature that optimizes fuel economy while maintaining ground speed by automatically adjusting engine speed and transmission settings based on load. This new feature has the potential to save customers upwards of 20 percent in fuel with no loss in productivity in many applications. A new push button throttle controls engine RPM, as opposed to a rotary dial. Speed increase and decrease buttons will cause engine RPM to either go to wide open throttle or to low idle. Pushing and holding the button will allow the operator to find the desired speed range.
Machine hydraulics were updated for improved performance and response, and offer new features when optional electro-hydraulic controls are ordered. A larger hydraulic pump is now available as standard equipment with the 550K and 650K for both mechanical controls and the updated electro-hydraulic system. The EH system on the 550K, 650K as well as the 700K is more responsive to operator inputs and the machine will significantly grade better when equipped with a grade control system.
The 700K has two additional blade size options that were previously not available to help match machine performance and increase productivity in grading/spreading applications. A new 126 inch blade is available in addition to the 120 inch blade on an XLT frame and a new 144 inch blade is available along with a 132 inch blade on an LGP frame.
To keep operators up and running, the 700K comes equipped with John Deere’s exclusive V-Cool package. This system incorporates a cool on demand hydraulically driven fan that isolates coolers from dust and engine heat for increased efficiency and durability. An automatic hydraulic reversing fan is optional for all models. A ground level courtesy lighting switch was added near the battery disconnect switch in the left rear service door and provides light for safe machine entry and egress.
