Quick Hitches Quick disconnect for 3 point

[Gary T72]

2 questions. What is the difference between a Cat1 and a Cat2 tractor/implement? I have a small JD 850 with 3 cyl Yanmar. Is that Cat1? Secondly, has anyone used the quick connect sold by Northern Tool, I believe its called Pat's Quick hitch. Thanks

See the chart below to explain the dimensions differences between CAT 1 and CAT 2
.. Your JD850 is CAT 1.. Yes hundreds if not thousands of our members have and use the Pat's quick hitch.

Here is an article that explains it better than I can.

Pat's system will save your back but a true quick hitch will allow you to just stay on the tractor, however there are inherent downfalls to the quick hitch, one being not all attachments you have will fit. A few of mine were off a bit and I had to move the connection points to make it work. But now I can dump the box blade off and pick it up in a matter of 30 seconds. Guess it depends on how often you change implements.

I have Pat's on my JD3032e
they work great and make a 2 person job that would still take 5 min to a 1 person taking less than a min
Pat's also gives you more room and flexibility to hook up your PTO than a true quick hitch
MY :2cents:

Here is my quick hitch in action.

I have the northern tool quick hitch, just for the op knowledge its different tan the pats system. YMMV but I prefer the quick hitch over the pats system but that's just my opinion.
