got a loader backhoe that's been burning through pumps and I'm trying to find something with better response time, this 420 series any good for that kind of work?

Question by: Lyle R on Jul 24, 2025, 7:30 AM

Loader backhoes are one of the core applications this pump was built around, so you're on the right track. The 420 Series is known for having some of the fastest response and recovery times available in its class, which matters a lot when you're cycling the loader arms repeatedly under load. The advanced control options also help the system run more efficiently, which tends to reduce heat buildup and stress on components over time. For a machine that's been hard on pumps, those two things together can make a real difference.
