Question by: Norm M on Dec 23, 2025, 5:20 PM
Got a loader backhoe that needs a new pump and I keep seeing this 420 series come up. Is that a application it's actually built for or just something folks slap on and hope works?

Loader backhoes are one of the core applications this pump was engineered around, so you're not guessing on that one. The X20 series in the 420 line covers a broad range of mobile equipment, and loader backhoes sit right at the top of that list alongside crawlers, mini excavators, and articulated haulers. The 3.80 CID displacement with high pressure and flow capacity is sized to handle the kind of continuous demand that equipment puts on a hydraulic system.
