Question by: Brenda S on Jun 7, 2025, 10:46 AM
If I'm usin' this on a tractor, how's it hold up in the heat and dust?
Answer by: Customer Support on Jun 9, 2025, 6:58 AM
This open circuit piston pump is used in agriculture tractors, among other applications. It is designed to withstand the conditions typical of that environment.
Question by: Travis E on Feb 8, 2026, 2:44 PM
What kind of equipment is this pump actually built for? Got a loader backhoe and a couple ag tractors on the farm and trying to figure out if this'd work across both.
Answer by: Customer Support on Feb 10, 2026, 6:57 AM
Both of those applications are right in the wheelhouse for this pump. The 420 Series covers loader backhoes and agriculture tractors, along with a pretty wide range of other mobile equipment like mining machinery, dump truck lifts, railroad equipment, and material handling trucks. It's an open circuit piston pump, so it's matched to the kind of variable-demand work those machines put it through day in and day out.
