Recently purchased 8030 2wd with PS trans. The issue I have with the tractor is the clutch is not stopping tractor.
Basically non existent, it feels like there is resistance when you depress the pedal but it doesn’t effect the tractors movement what so ever. The cable is working properly, along with the kickback into 4th gear like it should. Looking for advice on where to begin my search on what’s causing this issue

If it clearly and cleanly shifts thru all six speeds correctly, I'm thinking there's something broken or stuck in the inching valve spool. Remove right step and swing out the batteries, let the fuel tank sag down a bit and remove the Power Shift valve. The inching spool can be seen from the outside and it has to come out to stop tractor motion. I had one a couple years ago that had some debris get into it from the inside and kept the internal spool from moving outwards.
