John Deere is building on its lineup of SmartGrade crawler dozers with the integration of the machine control offering on the 750K and 850K models. Adding SmartGrade availability on these larger machines will improve job site accuracy and quality of work through the complete integration of the Topcon 3D-MC2 Grade Control System. The system is fully incorporated into the machine cabin, structures and software — delivering precise grading performance while eliminating vulnerable external masts and cables.
The 750K and 850K incorporate a PowerTech 6.8-L Final Tier 4 diesel engine with 165 hp and 205 hp, respectively. Both models feature Eco mode, which automatically adjusts engine power and transmission settings based on load while maintaining ground speed, to help optimize fuel economy.
