Product Questions & Answers

What kind of machines is this pump actually built for? Got a skid steer and a combine both needing work and trying to figure out if one pump covers both.
Question by: Cheryl S on Jan 22, 2026, 6:56 PM
Construction equipment and agriculture are both listed applications for this pump, so a skid steer and a combine are right in its wheelhouse. It's a closed-circuit variable displacement piston pump, which suits mobile equipment that sees changing load demands throughout the day. Whether it fits your specific machine comes down to matching the port configuration, displacement range, and shaft specs to what each unit calls for, but the application categories are a solid match.
