Question by: Merle H on Apr 3, 2026, 11:10 AM
what all kind of equipment is this pump built for? got a crawler dozer and a mini excavator both needin work done
Answer by: Customer Support on Apr 5, 2026, 6:43 AM
Quite a few machine types run well with this pump. The 420 series covers crawler dozers and mini excavators, but it also fits loader backhoes, ag tractors, concrete and asphalt pavers, container handling equipment, truck cranes, rough terrain forklifts, feller/bunchers, articulated haulers, and even tunnel boring equipment. If you're running both machines off similar hydraulic setups, this pump handles the kind of variable load conditions that come with that territory.
