Catagory 1, catagory 2 three point hitch difference?

[Airedale]

I am sure this subject has been discussed but I can not find anything with a search.

What I would like to know is the differences between catagory one and catagory two three point hitches.

I am thinking of getting into a larger tractor and most have catagory two three point hitches. What I would like to know is can I use my catagory one implements on a tractor with a catagory two hitch?

Thanks in advance,
Al

i also up sized in tractors from cat 1 hitch to cat 2. my cat 2 tractor came with bushings that slide over cat 1 pins to fit cat 2 hitch. bushings should be available at tsc or farm center. could also change pins on implements to cat 2 pins.

The short answer is you can still use cat 1 implements with a cat 2 hitch, as long as you have bushings. A few tractors, like my JD5105, even have hitch balls with different holes sized for both cat 1 and 2 draft pins.

A lot depends on the hp level. Going from 40 to 60hp may not seem like much but the 60hp tractor will probably pretzel ground-engaging cat 1 implements pretty fast. If it's something like a mower or a 3pt spreader that shouldn't be an issue. It looks like you have a Kubota B7500 - I don't think very many implements suitable for that are going to carry over to a utility tractor with a cat 2 hitch.

Yep... just went through this. I wouldn't switch out the draw pins or link pins to Cat 2. It's a pain to get the old one's off sometimes and then you can't use them with a Cat 1. Like bigdeer said, just get a set of bushings for your draw pins and a top link pin bushing. They slide right in the ball or over the pins and you are off and running. I'd get an extra just in case, but they work great. The only thing might be if you had an implement that you might want the extra strength of a Cat 2 pin - I'm thinking a rear blade or sub soiler?? That's the only reason I can think of to switch out the pins to the stronger pins over just using a bushing.

Happy tractoring, MORE POWER!

Here is another explanation from Tractor Data: TractorData.com - Three-Point Hitch

If you want to know the history just Google ag tractor 3 point hitch standards or go to the Fergerson Museum.

Here's something interesting, my neighbor has a 60 something HP tractor with Cat 1 hitch system.

I have a New Holland TN75 (60 PTO HP) with both Cat.1 and Cat. 2 lift arm balls. I have both Cat. 1 and Cat. 2 implements. I never use the Cat. 1 balls, just use the bushings for Cat.1 hookups.

As stated by others, be careful using the bigger tractor with smaller implements. You can destroy them if you're not careful.

Roy, Thank you for this article. It began to answer my question the best. I inherited a Kubota L3700SU tractor, with a Kodiak 5' Standard Duty mower. The pin on the mower is bent and I am trying to learn how to get a replacement for it. Maybe it is the one called the "draw pin" (lift pin?)? It is 5" long and 7/8" diameter. In trying to order a replacement I got hung up on Cat 1 and Cat 2 and other professional industry yada yada. The article you posted helped me get started in my understanding. Thank you. Laura R.
