The new 750K crawler dozer features a John Deere PowerTech™ 6.8-L IT4 diesel engine that provides 155-165 hp at 1,800 rpm. A hydrostatic transmission gives customers infinite speed control, power management, live power turns, counter rotation while staying in gear, and dynamic braking. A hydraulically driven cool-on-demand fan operates only as needed, decreases cab and bystander noise levels and cuts fuel consumption. The 750K comes equipped with John Deere’s exclusive V-Cool package. This system isolates coolers from dust and engine heat for increased efficiency and durability.
