What is cat 1 and cat2?

 

[bakerg]

The 3-point hitch comes in 5 different sizes, numbered from 0 to 4. The differences between them are the dimensions of the triangle and the size of the three connecting pins.

The lower lift arms on a 3ph cat 1 are 26" wide, with the top link being 18 inches above the center line, between the two lower lift arms. The lower lift pins are 7/8" in diameter, and the top link pin is 3/4". The cat 1 hitch is used on tractors from 20-45 hp.

A cat 2 hitch is 32" wide. The top link is located 24" above the center line between the two lower lift pins. The lower lift pins are 1-1/8" inch in diameter. The top link pin is 1" in diameter. The larger Cat 2 hitch is designed for use with tractors ranging from 40-100 hp.

By definition, my Ford 1100 13HP tractor should be Cat 0, but its Cat 1. So if you're looking at a specific tractor, you might need to check the specs to see what category the 3P is. I'm limited to the smaller Cat 1 implements, but can run those just fine, and I think there's a bigger selection of Cat 1 vs Cat 0.

Hey - I realize this is an old post...but I have the same question.

In looking over the Kioti NX6010, it has this listed for the hitch type: "Standard Category Category I & II".

Does this mean you can use either Cat 1 or Cat 2 implements on the 3-point?

Also - Been lurking here for about 6 months now, very informative site, very helpful site.

Thanks,

Yes, and that would be true for really any cat II 3 point. Some mfg's ball in the draft links will have 2 hole's 1 for cat I 1 for cat II you just gave it a twist to line up the proper holes. Otherwise you just put a set of bushings on your cat I att to get them up to the cat II sizes. This does not work with quick hitches, cat I hitches only fit cat I att, cat II will only fit those, so on so forth.

Some manufactures make the lower arms reversible, you disconnect your lift links then remove your main lift arms and flip them end for end and side to side. If it shipped as a cat 1 the tractor end has mounted cat 1 pins with bushings to cat 2 so you can flip them to have cat 2 balls for your equipment and the cat 1 go back on the tractor mounts.

Ok, here goes. Category one is usually light weight attachments. A good example would be a 30 hp tractor and a 5 ft brush hog. The "pins" on the lower two connect parts on the implement for you 3 pt are smaller in diameter say about 3/4 of an inch.
When you get to a category ll, every thing is generally "beefed up and more rugged" I don't exactly what hp goes to category ll. I think it goes category ll when you get around a 50 hp tractor. When you get to category ll, those same pins I described above at about 3/4 of an inch are beefed up and have a diameter of say 1 inch or so. On a category ll, the arms on the tractor are beefed up and a lot heavier duty than that on a category l tractor. Now if you change the pins on a category ll to 3/4 category l pins, yes theoretical it would hook up to a category l tractor. Problem is you would not have enough tractor to pull it. So things would not work out. Now if you took say a 5 ft brush hog and put category ll pins in it then it would hook to a category l l tractor. Changing this pins is basically the same as changing out a bolt. Now lets say you put category 'll pins in a 5 ft brush hog and hooked to a 75 hp tractor. Yes it would work, but it would be very awkward and the size of your tractor would be big time over kill. A 75 hp tractor can usually easily handle a 7 ft brush hog. Hope this explanation and example help
