Excuse me and move this where it needs to be. I thought this might be useful to someone else.
I have a King Kutter middle buster(see sig) and have used it before without issue but... I used it when I had the top half of the ROPS removed and stored in the garage.
This past fall I read a few "rollover" posts and decided to put the top half of the ROPS on and keep it folded and pinned in the lowest rearward position to be moved upright when needed. Like a lot of others here, I don't have the height needed on my garage to drive the tractor in with the ROPS up.
Today I hooked up the middle buster onto the IMatch, got on the tractor and while I was driving away, raised the 3PT. I heard a loud bang and turned around to see that the middle buster's upper frame was within a 1/4 inch of the middle of the ROPS.
Took the tractor to the garage and surveyed the damage. Luckily there was none except a very small gouge into the lower portion of the folded ROPS and paint missing from the contacted area of the middle buster.
I imagine it could have been worse if the upper link on the 3PT was adjusted to a different angle/length. Not sure. Didn't have my phone with me so no pics.
My solution to the problem is to remove the pins at the lock position, raise the ROPS to the position just above the pins holes and put the pins back in so the ROPS is folded back but not locked down. This gives plenty of clearance between the ROPS and middle buster.
Just thought I'd give a heads up
