Need the 2 brackets that bolt to the back of the tractor and hang down for the tiller/sleeve hitch to mount on. Also the lift arm that bolts to the tiller/hitch where the cable attaches. Mount brackets are L-shaped, all 3 brackets have an offset bend.
Parts # 13, 14 & 15 in this diagram.
If that attachment won't open the 2 brackets are #58 and 85 on the following web page.
New or used, Thanks for any help.
