quick hitch

[clee4020]

Just curious as to why the HF quick hitch top hook is not compatible. As has been discussed here before, there are a couple of easy fixes that take care of some top hook issues. Some of the HF top hooks seem undersized because they aren't forged straight but a little grinding on the inside fixes that. The other problem is that some implements have a narrow top hook frame and the bolts on the QH interfere. This is fixed by using short pins so the bolt head doesn't stick out.

One problem is the bolts are interfereing. I am comparing it the JD quick hitch and JD implements. It appears that HF quick hitch top hook needs to be about a 1/2" or lower than the lowest setting. I have considered cutting off the adjustable, pin-holed portion and weld the top hook where it needs to be to fit our implements.

HF quick hitch top hook is set to quick hitch specs in its lowest setting.

Does anyone know the quick hitch measurements? I seem to remember a picture with a triangle and measurements for the standard but I can't seem to find it.

There used to be another one at tractorsmart.com, now it's just kubota sales... Steve

For some reason I couldn't find a diagram on the web either, but I know the ASAE spec for Cat I quick hitch compatible implements. (The spec is for compatible implements, not quick hitches. QH manufacturers are supposed to build to meet the implement spec.) The minimum spread between the base of the bottom pins is 26.9" (the spec assumes open pins so it doesn't specify a maximum width of the quick hitch itself). The vertical distance between the centerlines of the lower and upper pins is 15.0". The spec requires that the implement pins be Cat III sizing - 1.25" upper pin and 1-7/16 (1.4375) lower pins although, as we have discussed in other threads, some manufacturers build quick hitches assuming Cat II pin sizing.

That is how I understand it to be too. ^^^^^^


Clee 4020,
I would check to see that you have the properr sized pins for your hitch if it appears to be a 1/2" out of alignment for the top link hook.

once you gave me more information I found it.

I may be wrong, but I didn't think there is an industry standard or spec for quick hitch dimensions but more of an acceptable range...I am using Cat 2 top link (1") pins on implements and the HF quick hitch won't work with our JD Cat. 2 implements and the JD quick hitch works fine with these implements.

The quick hitch is supposed to meet a ASAE spec.

As with most things, that's what is nice about standards - so many to choose from!
