  • Plow question for Scott or others
  • I have a 12 AO 28 two bottom plow. It's marked FERGUSON Harry Ferguson Inc Detroit Michigan so I know it's from '45/'47. The serial number is 51833. I picked it up when I picked up my '46 2n from original owner but he could remember if his father bought it at the same time as the tractor or later. Anybody know the year by the serial number on the plow.
    Thanks, Kirk

  • Kirk, here's some info that I have that may help some:

    Identifying Info on 1939-47 Ferguson Plows

    The first Ferguson 14" plows were model 14A from 1939-1942. “FERGUSON/SHERMAN Dearborn MI” was displayed on the ID plate on this model. The cast A-frame for the top link was used on this model. The smooth rolling rear wheel was installed on 1939-1941 models. Then they were held on with 4 rivets from 1942 on, along with a different arm with a spring and pins for down pressure. The Ford script in the right beam was on the 1941 to 1942 models.

    From 1943-1947, the plows were designated as model 14AO-28 or 14AO-40.
    From 1943 to about 1944, the plate displayed “FERGUSON Harry Ferguson Inc Dearborn, MI”.
    From about 1945-1947, the plate displayed “FERGUSON Harry Ferguson Inc Detroit, MI”.

    1939-1943 plows had the ID plate on the cross frame on the back of the plow, from 1944-1947 it was on the steel upright strap from the frame to the top link connection.

    For 1943 the cross shaft u-bolt clamp was changed to a steel plate on the outside of the beam, instead of the u-bolt going through the beam.

    The 14-AO-28 frame came out around 1944, earlier ones had a 1 5/8" drawbar then about 1946 they changed to a 1 3/4" drawbar.

    If the upright to the top link hole is all cast together on each side, then it is a 1941.
    If the vertical part is cast and the angled braces are steel, then it is a 1942.

    I had seen a copy of this before even printed it out but I guess I missed the part about the drawbar change. I guess because it does have the 1 3/4" drawbar it would be a '46 or '47. Thanks for posting it again Ed.
