Have a 75xt that the aux hydraulics are super weak, will turn a post hole auger but very slow even with motor at full rev, regular hydraulics like lift and tilt are fine, has been like this since I've had it and have tried all the simple things like adjusting the cable, replacing all the hyd filters thinking mayby a blockage or something and am at whits end, the aux hydraulics don't stall out or anything when putting pressure on attachments they just seem weak, any help would be greatly appreciated-Alan
