....there be in the 'kingpin' that holds my 54'' plow blade to the mounting bracket/lift frame assembly? i've got the power up/down and left/right. was grading the drive today, and after i put it back in the garage i noticed the blade moved a bit after i shut the tractor off and lowered the blade to the concrete. looks like its loose at the one large bolt that the blade pivots on. maybe i just don't remember or never paid attention to it, but i used to think that it was nice and tight. looked underneath it tonight with the blade up, but didn't notice anything out of place. can anyone learn me real quick on this?

My blade has a fair little bit of slop, but it's 25 plus years old and seen who knows how much service.

I should take it apart, buy a new kingpin bolt, and go see a machinist about tightening things back up.

Mine has very little slop to it, I've had to tighten the nut and locknut (not sure that is orginal) on it and I do that about once a year. It has really helped to keep it from "shifting" while I'm working it.

from moving it with the tractor off and the blade in the air, it has to be the kingpin, or the hole. not much else too it. i've crawled under there to look a couple times, and haven't seen anything out of the ordinary (loose bolt/wallowed out hole/etc.) i suppose i'll have to pull the angle cylinder bracket and take that blade off, will post pics of whatever i hapen to find this week

About once a year I loosen the lock nut tighten it up just a tad and tighten the lock nut. Dont't overdue, just kinda snug.

i suppose i should probably try that first, before i take the blade off. it sure didn't look like anything was loose under there, but i guess that really isn't a substitute from just putting a couple wrenches on it

I am in the process of restoring my blade for a paint job this spring and it had a fair amount of play on the main swivel pin so I enlarged the hole and made some bushings for it with a new pin. Here's a couple of pics.
