| Got a N5 that stopped moving suddenly when unloading corn, will not go forward or reverse. When it happened, I heard a little bit of a clunk and then it stopped moving. Combine hydraulics are also slow and will only work unless revved high. I replaced all the hydraulic filters the morning after and everything was back to normal, ran corn for about a hour and then once again, I heard a slight clunk and no forward motion or reverse. Main belt coming off the engine is not broken and seems tight. Any ideas? |

| Sounds to me like the hydraulic system isn't keeping the hydro charge pressure steady. I'd say it's time for some hydraulic pump testing with multiple gauges and for sure a charge pressure gauge from the pressure reducing valve to the hydro. This is kind of serious as you could smoke the hydro from lack of charge/lube pressure. No, I have never seen this happen before. |
