Quick hitch or direct connect to three point ?

[Catman8]

I notice when my tiller is hooked up to my quick hitch there is a lot of free play at the connection points and when the tiller starts bucking it slams back and forth beating the heck out of the QH. And I find the same is true for other implements that are attached using the QH. When an implement is attached directly to the three point there is no free play. I also notice when using a QH the weight of the QH is pushing down on your implement and when hooked directly to the three point there is no weight pushing down on your implement.

Do you feel that the free play on the QH and constant back and forth banging causes stress to your implements or tractor that are not present when connected directly to the three point?

Do you feel the weight of a quick hitch pushing down on a tiller changes the normal function or operation from no weight when hooked directly to the three point?

Haven't noticed the free play you are describing on my I-match quick hitch. Are you using the right size bushings on your implements?

Yes these are the bushings that came with the QH, I don't have a pic of the free play but the bushing can move back and forth, I'm guessing 1/8" or more of free play, just enough to allow it to hammer back and forth.

Reducing all the clearance between the QH hooks and the bushings would take the "quick" out of the hitch and some QH's have differing amounts of clearance in the hooks due to manufacturing tolerances. There is a little trade off when using attachments like QH's especially with dynamic loads like a tiller. As far as the weight of the QH pushing the tiller deeper in the soil...I think the tiller is heavy enough by itself to do that and the weight of the QH is not at fault.

Don't think I'd want a QH. Broke the tensioners on my 4010 because I didn't keep them ultra tight, to keep the bush hog from swinging. A little extra length from a QH would apply even more force on such things.

With dollies underneath heavy stuff, I can hitch things up to the 3ph with no problems. Finally got another U joint coupler where you push the button rather than pull back a collar (while trying to push the whole mess the other way) helped a lot with that bit.

I too don't have all that much free play. I recently bought a 6' tiller and put it behind a Ford 3000 (40 HPish) with Pat's quick hitches and I use the pin adapters that come with it (bent over flat washer with a cut out in it). I have 5 hours on it probably running on dried clay, very hard, very hard on equipment. I did look back several times and everything, tiller included was jumping up and down but considering what I was tilling, it was to be expected. I checked the Pat's mounting when finished and it was still tight. If you are running a Cat 1 tiller on a Cat 2 3p then you could expect vibration if you don't install cat 2 adapters on your Cat 1 linkages. TSC has them.

I took some better pics to show the free play you have with a quick hitch, the top hook has the most. Another thing I noticed with a QH is if you have your three point all the way down to draft the latches are what is pushing on the bushings instead of being retained in the curve.

I just feel that the hammering affect with the free play causes a lot of shock load.

That top hook is your problem, it looks like it doesn't have a bushing. That would explain why your tiller is banging around.

When you buy a QH compatible implement does everyone need to add a bigger bushing for the top link, this size bushing takes up most of the slop except for about 1/8"

Yes, the top link bushing should have an outside dia. of 1 1/4". On my I-match I would guess the slop is around 1/16" - 1/8".
