I get grease contact when attaching / removing things from my 3pt hitch. I keep the threads on the toplink lubed, and the adjustable link has a lube point, and I lube the hitch pin points and on the top link swivel as well. Probably overkill, but then.. I never did this on my yanmar 1700, and I replaced the adjustable lift link once.. and it might have been a failure due to no lube.

I use my tractor a good bit and do not have this problem. "
