A feller-buncher includes a work tool having a hydraulically powered blade. The feller-buncher also includes a first axle having a number of first wheels attached thereto and a first hydraulic motor operable to rotate the first axle. The feller-buncher also includes a first hydraulic pump operable to supply pressurized hydraulic fluid to the first hydraulic motor and a second hydraulic pump operable to supply pressurized hydraulic fluid to both the work tool and the first hydraulic motor. Yet further, the feller-buncher includes a load sensing circuit for sensing a load on the work tool when the work tool is contacting a tree. The first hydraulic pump is configured to adjust hydraulic fluid flow to the first hydraulic motor based on the load on the work tool sensed by the load sensing circuit. A method for operating a feller-buncher is also disclosed.
