The 3 pt hitch on my B7100D (gear) will lift my brush hog for awhile but slowly loses pressure and lowers the implement so that I have to raise it again with the control lever.
The problem has been getting slowly worse over time.
My understanding is that the possible reasons are:
1. A worn oil pressure piston O ring, piston or cylinder.
2. Faulty control valve
3. Faulty spool
Has anyone undertaken an overhaul of the hydraulic lift system and could you advise of the most likely cause and how you approached the overhaul.
