3PH arms hit rear tires

Also be careful of the geometry of the turnbuckles & 3 pt arms. Sometimes when you lift the 3 pt all the way up, the turnbuckles can become very tight causing undue stress on them. Possibly leading to breakage of the weakest link. Hopefully it's the turnbuckle /forums/images/graemlins/grin.gif

( I would watch the equiptment until I was comfortable that it will not hit )

If you do your adjusting with the implement up in the air a little it is easy to center and you can sway it some to make sure the arms don't hit.

Here are some general rules when it come to sway chain adjustment:
For ground engaging implements such as plows and boxblades, landscape rakes etc. leave a 1-2" sway after centering the implement between the tires. Adjust left and right chains to center, and then lock them down with the nuts. It's good to use a wrench unless you have the jam nut (two nuts) type locks on your turnbuckles, otherwise they will loosen while you're working.

For PTO equipment, such as rotary cutter, tillers, etc., it's best to tighten the chains completely, leaving no sway in the implement.

If you have a problem with the chains tightening too much when you lift the hitch all the way up, and the implement was centered properly between the tires, the chains are too short and should be replaced. They should allow full movement from up to down position without a problem.

John,
Maybe a dumb question...( If you have a problem with the chains tightening too much when you lift the hitch all the way up, and the implement was centered properly between the tires, the chains are too short and should be replaced.)
In your example of tightening up the chains completely, if you have that problem above when lifting...what do you replace the "short" chains with? Correct me if I'm missing the point here, but if you put on longer chains like you say, but tighten them up again, wouldn't they now be the same as the other ones? And wouldn't they again cause the same problem?

It seems to me the connection point of the chains should change to allow tightnes throughout the upward/entire movement of the 3pt?

I didn't have time to check much on this today, however I did take a quick look and noticed the side to side of the arms is entirely on ball/socket type points and I couldn't see how chain adjustment would change this problem. However I have not had time to read the owners manual yet either.
