highway - don't feel that you are alone on this. 38+ years and up until now - I didn't even know of this potential situation. I've always been aware that you must run the implement full up/down to ensure the 3-point system does not "bind up". This was of particular concern when I had my first tractor. It had a turnbuckle/lock nut system and could be "locked down" tight.
With my tractor now and the telescopic stabilizer system - it's not really possible to adjust the 3-point system to a dead nuts tight configuration.
One of the big concerns for any stabilizer system - you will PUSH with the implement and cause damage because one of the stabilizer arms will be in compression. That is why the recommendation with a 3-point implement is - never push. Even when plowing snow I will not push with my rear blade. It can be a real PITA - but I will turn the tractor around and PULL to complete any grading/leveling operation.
There are some well made/highly recommended after market stabilizer arms. Perhaps if you google "stabilizer arms" you can find the posts with links to these arms.
Oosik--Yep, I broke mine backing up. As you say it's pretty hard to completely avoid backing up, esp if your fields aren't "square." I've order after-market and meantime while I wait for them, no backing up! My prior tractor was a Deere 950 and the links on the hitch arms were built like the proverbial brick -house. Made it pretty hard to mount and dis-mount an implement. I've now solved that problem with a generic brand Farm & Fleet quik hitch. It has a little more slop than I think it should, but so far nothing's falling off....
