I have seen a few messages that have mentioned a float capability on 3 point hitches, however I can find no mention of it in my 4310 manual - maybe I just missed it. Does the 4310 have this capability? If so, how does it work?

It is just there. You have hydraulic pressure to raise the hitch but it drops by gravity.
There is no hydraulic down pressure on your 3 point hitch.
Your loader, on the other hand, if it is adjusted properly, should create enough down pressure to lift the tractor off the ground.
It has a float setting, but you must choose it by pushing the control fully forward.
Sorry if this is more than you asked for or stuff you already know.

kwschumm, check out page 41 in your owner's manual. It tells you how to set the rockshaft hardware for float and rigid operation. ....

I remember a discussion quite awhile back about a JD having a selector for lateral float on the 3ph. In the lateral float position, one lower link arm can rise independent of the other. I don't know if that's the feature described in the manual. I've never seen the feature, I just remember the discussion and I'm not sure it was here.
The idea of a lateral float would be a bit different than the usual sense of 3ph float. In this sense, a 3ph is in float whenever the position control is set lower than an implement is operating. Sometimes you hear people say they increase the float (push the quadrant lever further down) to allow an implement to follow the ground contour more closely. An example that people with 3ph mowers may encounter is cresting a hill and having the mower pull off the ground if the position control isn't set low enough.
In that case, there's not enough float (meaning the difference between the height the mower is operating and depth set on the 3ph. When the front of a tractor crest a hill and starts down, the lower link arms will rise unless the 3ph can lower. Sometimes you hear of people 'holding position control,' meaning setting the 3ph position so an implement just rests on the ground. Sometimes the idea is to try and cut the tops off of bumps or maybe clear deep snow in several passes. For working ground, holding position control doesn't usually work that well because an implement will move opposite of the ups and downs the front wheels take rather than follow the ground contour an implement is traveling over.

I saw that section of the manual (thanks Chief) but I thought there was more to it than that (Rockshaft float?). It didn't seem to apply to my 4310 which has both Top-N-Tilt and iMatch. When Top-N-Tilt is installed the draft link stops are completely removed, allowing the draft links to float. With iMatch it looks to me like the implement is also free to float since all three mount points can pivot up and down. A few days ago I used the bush hog for a few hours and didn't seem to have any problems going over some rough ground, but I don't want to learn an expensive lesson by bending or breaking something.

The mention of the bush hog brings to mind a little trick that is common to most 3pth mowers, and some other 3pth-mounted implements which require 'contour following' in order to work effectively, it will eliminate the most common cause of bent hitch hardware. If you don't already know about it, here it is again.
When using any 3pth-mounted implement such as a bush hog, replace the normal upper link with a stout piece of chain the same length (or just alittle longer) as the upper link. This will allow the implement to rotate about the two lower pins without any resistance, which could exert enough force to bend the linkage, while still retaining the ability to lift the implement normally.
This is really handy on uneven ground or when crossing shallow gullys like ditches.
Best of luck. ....
