Cat 1 vs. Cat 2 3-point Question

   / Cat 1 vs. Cat 2 3-point Question #11  
All the MX series have a straight Cat 2 hitch.

Kubota supplies several bushings to "fatten" Cat 1 pins to fit Cat 2 fittings in the MX toolbox.

Kubota describes this combination as a Cat 1/Cat 2 hitch. I like it because it is simple.

Some older tractors have hitch fittings which swivel between Cat 1 and Cat 2 fittings. Some current model Mahindra tractors have swiveling bullseyes. Too complicated.

Cat 2 hitches are considerably more robust than Cat 1 hitches and adjustable parts typically extend further. Parts are not interchangeable.


L3560 implements are usually 60" or 66" wide. MX implements tend to be purchased 72" wide because of bigger MX wheels. Therefore you may show tire tracks behind implements borrowed from your neighbor.

An open station Kubota L3560, lightest and smallest of Kubota's Grand L tractors, weighs within 200 pounds of an MX bare tractor. Because of modest horsepower, L3560 tires are sometimes inflated with air, sometimes filled with liquid. My L3560 tires are inflated with air. MX tractor tires are almost always liquid filled. MX5800 often carry iron wheel weights and have liquid filled tires to apply 61-horsepower to ground without losing traction.


OK, I get it. This sounds like what in Motorsport are called "Rod End Sleeves". Allows one to insert a smaller diameter bolt through a rod end or spherical bearing than what the bearing was designed for.

In common tractor-speak these fittings are called bullseyes.

Thanks for that Jeff. Gustave

So, some of this explains why I have a dickens of a time getting my RFM (Woods 72") mounted on the International1066 (which I think has Cat 3 hitch)

I get that the fitting size is bigger.... but the arms don't come together as close as the IH 444 tractor does (Cat 2).

I get that a larger tractor might have to go wider.... I just erroneously presumed they'd all close in to a similar distance


The ONE time I used my RFM behind the big International, (Backstory: I don't have the top-link) I simply hooked it to the two arms and pulled it around the field. Since I had no intent of raising it, I thought I could get by letting it float better without the toplink.

Though it did "work like a charm", I had to wrestle the bugger to get the arms in close enough to make it fit.

I've never done that since.

Lower Links minimum widths:

Cat 1 = 28"

Cat 2 = 34"

Cat 3 = 40"
