So I go to pick up my tractor yesterday after FINALLY getting the Power Beyond kit installed. Yay! I start the tractor and immediately notice that the rock shaft is whining and shaking like crazy. I lower it some, same result. I put it in any and all positions, same thing. Lower it all the way down, it stops. What the heck?! Go get the service manager. Him and 3 other techs have no idea, one of them acts like he had never seen a tractor before. Boy I wish I had purchased this elsewhere. Any idea what would cause it to do that?
