Just bought a grand l6060 and it was delivered this week. Had the dealer install factory kubota third function valve for auger and grapple work. I owned the grapple and have used on a skid steer before hence it has flat face fittings. Had the dealer install flat face in the tractor and the auger I bought with the tractor land pride sa20 rated to be usable by the tractor. Connected the auger and it barely turns it half a turn either direction. Then tried the grapple and it won’t open / close it either. Contacted the sales man and he said he would have the shop call me Monday but…. I have the engine rev’d up when trying it the hoses jerk so I can tell they are trying…. I have a video I can post if I can figure out how. I’m wondering if anyone else has ever seen this or would know what might cause it? Thoughts?
