Question by: Todd T on Jan 5, 2026, 12:01 PM
Got a mini excavator and a crawler dozer both needin' pump work done this season. This 420 Series fit either one of them machines?
Answer by: Customer Support on Jan 7, 2026, 6:36 AM
Both of those are squarely in the application range for this pump. The 420 Series X20 open circuit piston pump covers mini excavators and crawler dozers among several other mobile equipment types, so you're not stretching it to use it across that kind of fleet. The C-Mount configuration and 4.88 CID (80 cc) displacement make it a practical fit for the hydraulic demands those machines put on a pump day in and day out.
