Where I would be looking to make this decision is price. $350 for a CAT I hitch is terribly high. You can buy a very well built CAT II hitch for less in an off brand.
I use the snot out of my QH. It has to be well built and stout with quality materials. Being JD green with an imatch sticker does not guarantee that.
Didn't you break a elcheapo QH with a B series Kubota?
