Mounting a ripper.
Hi, DPete.
Regardless of whether your 40A has the correct mounting holes for that plate or not, as I understand it, the D4D was the first D4 model to be offered with a back end designed to cope with the stresses of a rear mounted ripper. I would suggest looking at the load transfer bracket that Old Magnet mentioned. These were designed to transfer the real loading of pulling a rear mounted ripper through hard material to the drawbar pull point under the tractor where the swinging drawbar attached. I useta did had a sketch of the brace wunsa ponna time but I cain;t find it now. Maybe somebody who pas a parts book for a 941 or 951 will be so kind as to post the appropriate page(s)
Just my 0.02.
You have a wonderful day. Best wishes.
