What does the chain do on the 3pt reciever hitches as seen on Chiefs and Kwschumm's pics?

Plots, the 3pth on almost all tractors is not capable of downpressure, if you were to lift the hitch it would rise up. This is a safety feature to prevent damage if an implement were to bottom out, the hitch can lift rather than bending or breaking something.
When you put a trailer hitch on a 3pth this factor becomes a potential problem. If the trailer were to become unbalanced and exert up-force on the 3pth it would go up. In order to prevent this happening there is a safety chain placed between the hitch and drawbar which is fixed and prevents upward motion.
Best of luck. ....

It is a safety chain. Three point hitches do not exert downward pressure. The safety chain attaches on one end to the swinging/rigid drawbar while the other end hooks in the receiver hitch at the desired position. This locks the hitch from going upward when upward movement isn't wanted.
For instance:
1. If you have an 8 foot long utility trailer and put ramps at the rear and drive a garden tractor up, as you get about half way up the trailer, the hitch will suddenly fly up about 6" and the tail of the trailer will go down. It will scare the he** out of you and could cause damage or injury.
2. If you have a dump trailer and raise the load, the center-of-gravity will change and move rearward causing a negative tongue weight and the hitch will abruptly fly up.
3. If you are backing a heavy trailer into a building and you have a ledge at the edge of the doorway that you must go up, because of the resistance, the trailer could cause the hitch to fly up again.
4. If you are backing a trailer up a steep slope as was mentioned last week in one of the discussions and also attempt to negotiate a turn at the same time, the hitch will not only swing sideways against the turn-buckles but will most likely cause the hitch to go up. This same thing can happen as in point (3.) if you are turning and backing up into a building.
In other words, if you have a receiver hitch it is best to have a safety chain. Chief made is own hitch but seems to have a somewhat weak chain. Ken bought his from Bad River Inc. I have one also.
The safety chain can be adjusted to any desired height by placing the link in the appropriate slot. SAFETY should always be your primary concern when working around implements particularly if they are heavy. ....

Well said and well covered gentlemen! I move my boat around with the hitch as well as other smaller trailers and I cringe at the thought of the boat trailer rearing up while pulling it up hill; there would surely be no way to stop it. The chain in the picture is too small for the job and I have since upgraded to a doubled 3/16" cable which is much stronger. I have never had a trailer tongue rear up on me like that but the possibility exhists, so I use the cable. ....

Chief if your moving a boat with your set up I asume you can move pretty heavy objects using the 3 point. I like the idea of being able to latch onto a trailer easier with that set up but I'm concerned if it would safer just to use the draw bar dragging a 16 foot trailer around to gather wood? ....

Manufacturers recommend only towing from the drawbar. This keeps the towed load below the rear axle, which is important for the stability of the tractor. A heavy towed load from a 3-point receiver raised above the axle will add to the possibility of a torque over, both from the added extention of the load behind the tractor, and the eccentricity between the towing load and the tractor. The towing load is not the tongue weight, it is the force needed to move the trailer. For a heavy trailer with pnuematic tires on soft soil, towing loads can get pretty high, and increase dramatically going gup hill. Having this load above the rear axle with a loaded top link can be dangerous.
I have a 3-point reciever hitch, but only use it for convenience with lighter loads. For heavy loads, I follow the manufacturers recommendation and use the drawbar. ....

For moving almost anything I use a all-in-one combination quick-tach plate I made for the FEL. It has a 2"x2" receiver socket built in plus several hooks, a lifting eye, mounts for forks and a few other possibilities, including a 3pth adaptor.
Moving a trailer from the front takes a little getting used to, but after you get the hang of reversed steering it sure is handy.
The visibilty is phenomenal and the hitching is easier too.
Best of luck. ....

Beagle:
In theory you are probably correct. The problem is the tongue height on my triple axle flat bed doesn't match that swinging drawbar height nor does my dump trailer. My dump trailer tongue is very, very high. My F250 4x4 with off-road package still needs a 4" inverted drop to match the tongue height.
Safety and common sense are always important in all instances. ....

Height and ease of hook up have made these very popular. Like I said, I use one too. But the consequences exist, and should be communicated. I saw the results first hand, and it was awfull.
The best that could happen is have the manufacturers offer a solution based on the tractor. I know Kubota says only from the drawbar, I would suspect the rest are the same. It would be great if they came up with a solution that is engineered to be compatable with the equipment. ....
