Randy, you should post this on the main forum as that's for discussing the garden tractors, which your 122 is. You posted in the lawn tractor section. I'll post some photos in the main section for you.
I don't think they make the hitch for a cub anymore, but they make some details & you can get the (2) 191 straps made at a local machine shop. I have a 1450 & that is the way I got my 3 point hitch to work. Contact Bruce the Engineer at Brinly phone1-812-218-7200. good luck lindy
