hi everybody, my first post.
Symptoms of the problem are as follows:
Three-point linkage became sluggish and only worked with high revs
Drained the oil, checked the suction filter (had been punctured with a screwdriver or similar)refilled oil
Three-point linkage now failed altogether
The pressure release valve appeared normal and I have tried it in various positions
Measured pressure on trailer outlet- 1800 psi, accompanied by a change in engine noise
Some air bubbles seen in the oil
the present situation is that the three-point linkage will rise when the engine is cold, but has no strength, gets rapidly worse as the engine heats up
The advice that I have been given suggests hydraulic pump problem despite the reading on the trailer pipe. I have some doubts about this but would appreciate any advice.
