This morning while taking the hay mower off of our Oliver 1800 C we lost hydraulic power. I couldn't lift the mower and the steering became difficult.
I checked the fluid level and topped it off to "full" and replaced the hydraulic fluid filter. Then I removed the caps on the priority valve to check them. I did not remove the spool, I'll have to do that. After that we still didn't have power to lift the hay rake and the steering was hard.
To test it we let the three point drop and it raised, then we tried to lift our rotary hay rake using the remotes and it would not lift it. If I personally lifted up on the rake the hydraulics would reluctantly extend the cylinder. When we let it drop it dropped as normal.
Any thoughts on what went wrong in the hydraulic system? We use this tractor for mowing hay and running our sprayer with hydraulic pump so we need to have a functioning hydraulic system.
