Question by: Johnny R on Jan 24, 2026, 7:04 PM
We run loader backhoes and a couple dump truck lifts pretty hard through the season. This 80 CC pump hold up to that kind of back-to-back use?
Answer by: Customer Support on Jan 26, 2026, 11:15 AM
Both of those applications are right in the wheelhouse for this pump. The 420 Series is built specifically for mobile equipment running in demanding cycles, and loader backhoes and dump truck lifts are called out directly as supported applications. The high pressure and flow capacity is what makes it practical for that kind of work where you need consistent output without a lot of lag between use.

Will this pump work on my old tractor? It's an agricultural tractor, but pretty worn.
Answer by: Customer Support on Jul 26, 2025, 6:05 AM
This Danfoss/Eaton pump is often used on agricultural tractors, as noted in the applications. However, ensuring it's the right fit for your specific model would depend on the existing system specs and mounting compatibility.
