Did you happen to pull back on the little lever on the right fender that has a green button below it. If it faces towards the back of tractor push the green button to release lever.The small lever is a feature that allows you to set the 3 pt depth and leave the setting there. Then just pull back on the I think on mine it is a green color sleeve and the 3 pt goes all the way up make your turn and get back to where you want to drop implement push button 3 pt goes right back to position. I LOVE THAT FEATURE at least I think it is a feature

. I believe LS states in the manual it is a safety lock so someone will not drop the implement by accident. I personally would never use that as a safety, the only safe way to work around an implement on the back of a tractor is to properly block it up or remove from the tractor. So I use it to set my last 3 pt down level and use the small arm to raise my arms, then i just push the button and goes right back where it was. Sweet IMO.
