I was using my 7020 yesterday to haul silage yesterday with a Miller pro hydraulic rear unload wagon, it ran the conveyor no problem empty but wouldn't move it or very little once loaded with silage. What should I be checking, everything else was working fine, what kind of pressures should it have?

When is the last time the hydraulic filters in the transaxle housing were changed?

There is a T fitting on PTO valve with a cap on it. Hook a 5000 lb gauge to the fitting. Pull one of the remote levers with nothing hooked to it. Gauge should read at least 2300 PSI. MACK
