Ford 9n/ IH Cub/ Case VAH/Husquavarna riding mower
KUBOTA made 4520and 4530 backhoes in the 80s. They put them on most of thier B&L series tractors. You needed to purchase a seperate sub-frame for each model. They were a decent BH for lite duty digging around the ranch or farm. In a full time industrial operation they would not last too long.
