  • The coupler is original Dearborn made. Its intent was to extend the Pto to meet the stardards set up for all other tractor uniformity, which is that the PTO be about 6 inches ahead of the drawbar hook up, so the slidng drive on the machinery did not slide out to far and disconnect. The cross drawbar was usually dropped down to about 6" above ground to allow some up and down play over rough ground. This hook up got by to run a pull combine.
    This did not still meet the stanard of the PTo height being about 12 " above the drawbar height and the need to lower the drawbar so low.
    I don't know if the extension is 1 1/8" spline power in to meet Ford 1 1/8 spline and whether the extension is the stanard 1 3/8" out.
    Pulling a combine with this hook up caused a fire danger with straw being caught at drawbar. and plugging bellow muffler. My neighbor wired a piece of steel roofing under the tractor.
    With no live PTO it was necessary to back up enough distance so when the PTO was engaged to get combine up to speed, before straw entering.
    Another problem was plugging was eminent, you learned how to "SLAP" the tractor out of gear, before it stalled.
    A 8N could then handle a 6" header in 1st gear. My neighbor used a Mc Cormick 3" header. in 1950
    Doable but a bear to run.
    Me 10 years old then as sacker.

  • Here's your pictures. It is the Dearborn PTO Extension I show with my 8N below. Mine is shown with the safety shield attached.

  • That hitch and PTO extension is how we pulled our Woods Brothers Dearborn one row corn picker. Add a wagon on behind and the 8N had it's hands full.
    I used to enjoy driving down the road pulling the picker and 2 empty wagons. What a train.
    For the heck of it, I tried backing up with arrangement. I made about 15 feet. LOL

  • Re: 8N Coupler
  • Boy! It has been forever since I have used Imgur. So, I tried with no success I guess. I am looking at a coupler which attaches to the smaller PTO shaft and has the larger and more common PTO shaft at the other end. Kind of like an old over running coupler. Turn the shaft on one end and the other end turns the same amount. It would help if I could get an image here. Suggestions? Dave
