I have cleaned the filter, replaced the spooler value and the front buck hydraulics is still week. The bucket, once full, will drop once you let off of the lever. What do I check or replace next?
If the bucket is dropping after it is full & raised inicates that there is enough pressure to raise it , so I'd say the pump is OK. (There is a port on the tractor relief valve housing that a gauge can be hooked to to check pressure.) You either need to rebuild the cylinders or get a new control valve.
