I just noticed the other day after the wife did some mowing, she parked the tractor and we did some other chores and in abt 2hr the 62D deck dropped a couple inches. Also noticed when I had the disks on it that with the engine idling the 3pt would drop just slightly and then lift itself, this was cyclic abt every 5 sec. I talked to the service manager and he said there is a spec for hyd creep even though he disagrees with it, but the cyclic thing was not normal and so because I have the tractor in town today getting tubes and calcium in the rears he said to drop it off and they will check it over as it may be something as simple as an adj. I sure like my dealer though, he said don't worry abt picking it up... we will have someone drop it off at your place when we are done. It's a 25km trip one way, very nice to be treated like one of the big guns who spend 100's of thousands.
