IH 350 Utility + Cat 1 3 point fast hitch dimension question

Hello all,
I'd like to put a Cat 1 3-point on our 350 Utility. It has the fast hitch on it, so this should be a relatively easy addition. The problem is, I don't yet have any Cat 1 PTO driven equipment (planning to rent a 3pt tiller in a week or two). I want to make sure there's a proper distance for the PTO shaft. The width, lowest height, max height and min-max lift range dimensions I've been able to find, but I'm not sure what sort of distance from the pins to the PTO I need to build in. For example, when the implement pins are level with the PTO shaft, what is the distance from the center of the pins to say the lock-notch on the PTO shaft? Or, when the PTO is level, what is the distance from the PTO lock notch to the pins and the PTO/Pins vertical offset? Or if someone happens to have a set of Cat 1 fast hitch lowers, the dimensions of those?

Thanks for any help you guys can provide. Since one should be able to adapt cat 1 implement onto cat 2 with just bushings, I've been tempted to just measure the distance on one of our Cat 2 tractors and duplicate that if I can't get a measurement from a cat 1 setup. I'm just hoping to build it to match cat 1 standards from the start to minimize future "quirks".

With a setup like yours,all bets are off. Best thing is to mount the tiller and measure while on the tractor.You outfit will be
'nonstandard' so a bit of 'adjusting' will be in order.

I agree that it'll be non-standard in that it's not OEM, but even the manufacturers have to agree to follow some sort of standard with their OEM 3 point systems, otherwise every implement and every tractor combination would require different setups. All I need is the distance from the pins to the PTO of a known working system. I'm asking to try and avoid spending $150 to rent a piece of PTO driven Cat 1 equipment just to get 1 measurement from it.

Thanks,
Chris

On the 350U up at the farm we have two different types of hitch. The bars that slide into the 2 point hitch are about two inches long or short of the other set. You will also need a ridged adapter bar up top where the "three" point part hooks up. You might need a longer or shorter PTO shaft. Sorry for sounding a little crazy but YOU will be by the time you get everything fitted up. When you are done it should work!

I've got a 350u that has had a tiller hooked up to it occasionally, I'll go out and get that measurement for you and post it

from the center of lower lift pin to center of lock notch on pto shaft is 16 inches on my 350u, thats staight out from the pto shaft. i've got 3pt adapters on my fast hitch and the tiller i used worked fine with no adjustments

I can be corrected, or perhaps I don't know what you mean, but when I put a 3 point adapter into a fast hitch, I don't even think of the PTO shaft. Unless it is a cheap implement made in China or somewhere, any implement will work ok. The problem is possibly the offset of the pto shaft on the A/SA which might cause a problem, not a straight shaft that fits most anything.

Thanks for the measurement Tom!

My goal is to get the fast hitch adapters set so that they're long enough that connecting a PTO isn't an issue and that it won't stuff the pto shaft during up/down movement, but not so far out that there's minimal drive surface in the PTO that it ends up twisting or damaging a PTO shaft. Being that I don't own any Cat 1 equipment yet, I have nothing to test with and I didn't want to assume that the distance on a Cat 2 hitch was necessarily the same for Cat 1 before building it, and I didn't want to have to rent equipment just to take measurements and test fit.

The physical building of the fast hitch spikes/arms and the 3rd point off the rocker is easy once you have the needed dimensions.

I'm attacking the problem from the other direction - I'm building the 3 point for the fast hitch, and I want it to work with standard equipment, which is why I'm asking about PTO length in hopes that if I get the dimension right I'll never have to think about it again. I had measured a friends brother in laws tiller, but when I saw it noticed it was some sort of simplicity abomination using cat 1 diameter pins on cat 0 spacing - and non adjustable. Plus that was only a 36" and I'm looking for something 6 foot to better fit the 350U.

Thanks for the help!

Per the ASABE standards the dimension from the end of the PTO shaft to the vertical plane of the lower link balls should be 19.7 to 22.6 inches (500 to 575mm) for a Cat
1 hitch. This is measured with the lift arms horizontal and spread to the standard 26" width.

Thanks! That's the exact standards based answer I was hoping for!
