Product Questions & Answers

Got a 62cc open circuit piston pump on a loader backhoe that's been giving us fits with slow response times. would this 420 series unit be a step up from what we're running?

Question by: Cheryl A on Jan 14, 2026, 8:22 AM

For loader backhoe work, the 420 Series is built around fast response and recovery, which is one of its standout characteristics compared to a lot of other open circuit piston pumps in this displacement class. At 3.80 cubic inches (62cc), the flow capacity lines up well with what loader backhoes typically demand, and the advanced control options on this platform give you more ways to dial in how the system behaves under variable load conditions. If sluggish response is your main complaint, that's exactly the kind of problem this series addresses.
