3-Point Hitch Standard Dimensions

Does anyone know the standard dimensions for a Cat. 1 3-Point Hitch? I was wondering what the distance was between the lift-arms and what the distance was from the center of the lift pin to the center of the top pin. I know that it can vary, but I was wondering what the standard measurements used to construct most implements are.

Thanks

Here is a very good layout of the 3pt cat sizes
Click here http://www.speeco.com/three-point.asp

also the weight limits off hand rule
Cat "0" 750 lbs (these are toy tractors mostly Chicom)
Cat 1 1000 ++ lbs
Cat 2 2000++ lbs

benny: Your lift weights are probably a bit low. I don't know the specs on Cat 0 or I but Cat II is 5000 lbs with weight centered at lower link pins and III is 7500 lbs. Now. I will admit that drops quickly with most implements as the weight is not centered at the lower link pins, but rather 100% behind the pins. Even at that 2000 lbs is low for CatII.

I know my 656 Farmall, Cat II quite easily handled a 3 point hitch sprayer 200 IMP gallons, and that would be 2000 lbs liquid plus 500 lbs of sprayer. I also had a 1066, Cat III and with 2500 lbs. front end weights added, you couldn't stump the hitch. I know we had it hooked to a Rockland Rotoveyor and the specs said that wighed 7500 lbs. at the hitch pins. Hitch pin weight is the only true comparison.

Sal Z: I'm kind of curious which you are trying to fabricate, and if indeed fabrication is your goal. Are you trying to fabricate implements, or a hitch for a particular tractor?

If you are planing to fabricate implements then follow the specs Joe has given you.

If you are into designing and fabricating a 3 point hitch for a tractor that was not engineered for 3 point hitch, you are into something much more complicated. Some of the considerations you must look at are; will the implement pull true and centered behind tractor, will the hitch have the lifting range to lower implement to ground as well as lift it high enough for normal movement and when completed will it lift the normal Cat I load safely. The design of some tractors is such, you will never achive all of these goals. Mounted equipment has never worked perfectly on tractors with configuration such that operator seat is behind rear axle center point. Some makes and model are easier than others to correct some of the problems I outlined above. I wouldn't want to comment further until I knew make and model of tractor.

I just finished building one such hitch, we didn't get it right the first time. In fact we did it by stages using a 3 point disk harrow to test each component. We had to change where vertical links hook to lower links to get the hitch lifting good weight. We then experimented with a chain for top link, trying to decide where on tractor, was best position for top link attaching. For example the first try, tractor lifted front of disk but back of disk was still on ground. To correct this we had to lower the attachment point of top link at tractor.

Almost every tractor will be different, study the features of factory 3 point hitches on tractors. Determine if you can incorperate those features on your fabrication. This requires some quite precise measurments and be prepared for changes.

I can tell you, my hitch was a fraction of the cost of any aftermarket hitches, and it lifts twice as much as the nationally advertized aftermarket hitch. It works well in field pulling disk as well. Contact me if you wish.

Sal: Go with the figures Joe gave you for Cat I, they will work fine on any factory Cat I tractor.

I want to fabricate an implement for a Cat. 1 hitch. I've measured a few implements and it seems that they are all a little different, so I was just wondering what the measurements "should" be. Thanks for the additional info too, its interesting. I do actually have an old cub lo-boy 154 that I've thought about building a hitch for. I could easily get the measurements from a factory hitch, but the hydraulics would be a pain. The tractor doesn't have any SCV's and only has one cylinder and valve to lift the deck. I guess I would have to divert the flow some how.

A while ago someone posted the chart for all these
dimensions. I looked for it but can't find it. BUT
I did copy it into my computer. I'm not smart enough
to get it out and post it. The dimension you want for Category one Are. width 26.8 " to 26.94 between
lower pins 18" center to center from lower pins to
top link hole. Otherwise known as mast height.
width of space at upper hitch point 1.75 inches.
The critical dimension is the 18" to high and the rear of the implement raises way high or is it way
low. TOO low and it does the opposite.

26 in wide and 7/8 lift pins, 3/4 top pin, 18 in height for cat I
32 in wide and 1 1/8 lift pins, 1 in top pin, 24 in height for cat II
38 in wide and 1 7/16 lift pins, 1 1/4, 27 in height for cat III. The height can vary to suit the equipment.

I'm working on building a scrape blade.
I went out yesterday and measured every piece
of 3 point equipment I have.
Widest one was 25.5 Rest were around 25 inches.

I had cut my steel to make 26 inches wide.
I'm thinking of cutting a little more off it.

Joe

That's exactly what I'm looking for. The widths you gave me are from the inside of one lift-arm bushing to the inside of the other correct?

Thanks
Sal

There's no standard that I'm aware of. That doesn't mean there isn't a standard. I just don't know. What I do know is that I've never seen any 2 impliments with the same geometry Cat I 3-point. Cat II stuff seems to be standard, but Cat I has a lot of variability. Of the 10 or so pieces of Cat I stuff in my yard, they probably vary from 26" to 30" on center for the lower link pins, with the top link pin varying between 24" and 30" above that. I simply do not have 2 that are the same. It's awful frustrating when you want to use a quick hitch....

Look on the left hand side of your computer screen under "research and info" at three point specs, that will get you started.

I should add, and then click on the link at the top of the three point specs page for the article with more info.
