Read articles →Filmed at Ohio State University with a hydraulics class, this video uses students to stress-test "Johnny X", a hydraulics-upgraded 1025R, against a stock machine, measuring real flow and PSI numbers through a power-beyond port and SCV, and logging hydraulic oil temperatures up to 200-210°F. The class setting drives genuine technical discussion, including why max PSI rises at high throttle and when flow loss begins above 190°F. Best for owners interested in 1025R hydraulic upgrade specifics.
An owner-operator channel where the host brings his personally modified tractor to an outside testing environment, so the perspective is enthusiast and hands-on rather than dealer or manufacturer.
Around 190 degrees, flow starts to decline because the oil is not functioning as well past that temperature.
The relief valve only lets so much oil by before building pressure, so once it fulfills that amount, pressure builds higher at high throttle.
Testing showed 8 gallons per minute flow and 400 PSI going straight through the power beyond port.
Yes, the Johnny X can run it, while the stock tractor would not because it does not load properly.
