Description

When your hydraulics start getting sluggish or your three-point hitch won’t lift like it used to, it’s often your internal pump telling you it needs attention. This internal pump is designed for David Brown 700, 800, and 900 series tractors, specifically the ones with the Selectamatic system that gives you that smooth, automatic depth control you rely on for consistent fieldwork.

What You’re Getting

Internal design that mounts right inside your transmission housing—no external lines to worry about
Proper flow characteristics to keep your Selectamatic draft control working like it should
Built to handle the pressure and heat that comes with running heavy implements all day
Direct replacement that installs without modifications or adapters

Built for Real Farm Work

This pump fits 770, 780, 880, 885, 990, 995, 996, 1190, and 1290 series David Brown tractors with Selectamatic systems. Whether you’re pulling a plow that needs steady draft control, running a cultivator where consistent depth matters, or operating a loader that demands responsive hydraulics, this pump delivers the flow your tractor was designed to have.

Made to Last

David Brown built these tractors to work hard, and this pump is engineered the same way. The internal mounting protects it from debris and weather, while the robust construction handles the constant cycling that comes with three-point operation and implement control. It’s built to maintain proper pressure even when you’re asking a lot from your hydraulics.

Good to Know

This is one job where you’ll want to think about professional installation—getting the transmission apart and properly sealed back up takes some know-how. When you’re in there, it’s a good time to check your seals and consider fresh hydraulic fluid. Seal kit 53439 is available separately if you want to do a complete refresh while everything’s apart.
