I hooked up to my auger yesterday to go drill some fence post holes. This was the first time I have used the auger on this tractor. I can raise the auger up with no problem, however as I lower slowly, when it gets about half way down it goes crazy, starts jumping and bouncing. I can drop it quickly with no problem, it just affects my accuracy. It does this with the pto on or off. I have no problems with my other implements; mowers, box blade, scraping blade etc etc. Any suggestions?
