Question by: Ross M on Nov 24, 2025, 10:06 AM

Will this Eaton-Danfoss pump fit on my older tractor backhoe without a bunch of modifications?

Answer by: Customer Support on Nov 26, 2025, 6:55 AM

This 420 Series open circuit piston pump is often used on loader backhoes, so it's likely a good fit, but you'll want to double-check your equipment's specs to make sure the 3.00 CID (49cc) displacement and mounting match up.

Question by: Rick S on Jan 28, 2026, 6:13 AM

What kind of equipment is this pump actually built for? Got a loader backhoe and a mini excavator on the same job site and tryin to figure out if one pump could work across both machines.

Answer by: Customer Support on Jan 29, 2026, 2:30 PM

Both of those machines are squarely in the application range for this pump. The 420 Series covers loader backhoes and mini excavators, along with a pretty wide spread of other mobile equipment like crawler dozers, articulate haulers, and rough terrain forklifts. It's an open circuit piston pump with 3.00 CID displacement, so it's built around the kind of variable load conditions you'd see moving between different pieces of equipment on a working site.
