Note
An optimum system match gives you a major productivity advantage. The 740 GC is an excellent match for the Cat 374F and 352F Hydraulic Excavators; and Cat 972M, 966M, and 962M Wheel Loaders. Having matched loading and hauling tools results in increased production and lower system costs per unit of volume moved.
