so i have a hf quick hitch and also the adapter bracket for non quick hitch compatible attachments. the adapter bracket looks as if it would make it a floating type top setup with attachments hooked to it? is this the case?

i have a rotary cutter,scrape blade and disc harrow
can anyone tell me what type set up float and none float attachments are used on all attachments,
new to this.growing up i just used whatever my grandfather had hooked up to his tractor

No. That isn't the purpose. The adapter is meant to be used on attachments where the 3pt connection isn't the exact size to match up to the Quick Hitch. While it does introduce some slop, I wouldn't call it "float".

But you should understand that a 3pt connection usually doesn't have any down-pressure so it is normally in "float" mode to begin with.

Very few 3pt attachments are meant to operate in a float mode (other than what the tractor already provides). If a specific attachment is intended to be used that way, it will have it's own setup for doing that. They don't rely on you having a Quick Hitch or the adapter for it.

I can only recall seeing one attachment that was meant to be used in a full float mode and that was a 3pt sweeper built by York. Most attachments have a rigid 3 point A-frame to connect to the tractor. But their's used a rigid connection for the two bottom pins and then a chain to connect to to top point. With that flexible chain, the sweeper could use the 2 bottom pins as a pivot and bounce up and down over things when used on an irregular surface. I've heard that some bush hogs used the same type of design but never actually seen one of those myself.

Actually, I believe that adapter yoke can be used to provide a floating top link. In some cases you may need to remove the top hook on the Quick Hitch to allow more movement.

The floating function is normally required with things like rear finish mowers. They ride along the ground on four wheels and while the 3PH can move up and down, if your top-link is fastened to a non-moving part on the mower, when the tractor goes over a hump or through a dip in the ground it can cause the mower to lift off the ground or bind. That is why you usually see the top-link on a rear finish mower secured with a chain instead of a rigid support. If using a Quick Hitch you can provide for some floating or pivoting by using an adapter yoke instead of having the implement riding in the hook.

My Land Pride quick hitch came with a floating adapter. As you can see, it provides basically the same function as the "Yoke". And, it too can be used to adapt an implement that is not Quick Hitch compatible.

Below is how a lot of finish mowers are attached so they can move up and down on the top link.

With a finish mower you are just towing it along the ground by the 3PH draft arms and the only thing the top-link connection provides is a way to lift it off the ground for transport.
