An optimum system match gives you a major productivity advantage. The Cat 730 is an excellent match for the Cat 349F and 336F Excavators; and Cat 972M, 966M, 962M and 950M Wheel Loaders. Having matched loading and hauling tools results in increased production and lower system costs per unit of volume moved.
