yeah, i think johnny products makes one that will work.
what makes no sense is they sell one for the xt1 and xt2, of which they have a single model of each that they rate for ground engaging implements.
i was just bored and looking on their website, it just makes no sense to not have one for your big shaft drive tractor that cub makes a point to market as ground engaging on their site but not sell a hitch themselves to actually do it (and then sell one for the lower end models that would be real iffy as actually capable off doing any work).
I know, first world problems.
