Question by: Earl H on Mar 4, 2026, 12:50 PM

What all can this pump run on, got a crawler dozer and a mini excavator both needin hydraulic work done, curious if one pump covers both machines.

Answer by: Customer Support on Mar 6, 2026, 6:13 AM

Both of those are right in the wheelhouse for this unit. The 420 Series covers crawler dozers and mini excavators, along with a pretty wide range of other mobile equipment like loader backhoes, agricultural tractors, and articulated haulers. The 4.88 CID (80cc) displacement and high pressure and flow capacity make it well suited for the kind of varied demand those machines put on a hydraulic system.
