  • Mounting a Dearborn mower on a Ford 600
  • I learned some new things today when mounting a Dearborn mower to a Ford 600 3 p0int.
    1. There is no female universal to switch from the 1 1/8"" to 1 3/8". I was able to
    purchase a 1 3/8" complete replacement shaft (meant for fertilizer spreaders) that
    will work however it comes in todays standard 3/4" X 7'8" rectangular shaft
    (so universals line up opposed). I purchased the shaft from tractor supply.
    I will have my buddy mill the 7/8" to 3/4" to make it fit the Dearborn 3/4" X 3/4"
    receptor. This will still require proper placement to make sure the universal are
    opposed. Some hacksawing of the rectangular shaft and receptor (new shaft comes with a quick coupler) adding a little extra length). The replacement shaft comes with the
    safety shield, which will replace the sheet metal shield that kept the hay from
    rapping around the shaft,
    2. The Ford 600 3 point lifts higher than an 8N. Moved the lever stop to the most
    highest position to stop the relief valve squeal. A permanent fix would be to extend the 8 3/4" arm extensions by 1".

    This mower will now let me mow the roadside ditch where my "sweet pea flowers" are
    grown for seed.

  • Well, yes there is. Three options -first follow LINK for 1-1/8" to 1-3/8" adaptor sleeve that slips over PTO shaft and pins. For about 5-6 bucks can't beat it and I've been using one for over 25 years. Option #2 is to purchase an Overrunning Clutch Assembly that has the 1-1/8" female end to your existing tractor PTO shaft and then the male end is the modern ASAE 1-3/8" splined shaft. Option #3 you have already chosen - purchase a new 1-3/8" PTO shaft and replace the original.

  • On a Dearborn 14-16 sickle rear mount, the in to out movement of the 3/4' square shaft is only about 3", with the down almost up to the weld to the universal which creates problems.
    1. This option of a sleeve would not work as the Ford 600 is already 1 3/8". not 1 1/8"
    2. The use of an overrunning clutch 1 3/8" female to 1 1/8" male, Would require shortening the square 3/4" implement female end to accomadate the extra length of the overrunning clutch.
    3. I decided on the purchase of a completely new drive shaft, that came with a 1 3/8" splined shaft,with snap coupler, and the standard 7/8" X 3/4" rectangular shaft and mill it to the Dearborn square 3/4". This shaft comes with the plastic safety shield also eliminates the bolt on shield that kept the cut hay from wrapping up on the shaf t and shorten the implement end by 1/2".
    A 4th option is to use the adapter I use on the Ferguson buzz saw 1 1/8" splined pulley. I cut apart a 1 3/8" splined drive shaft before the universal and welded a old 1 1/8" splined shaft. This created 4" more in length which required 4 inch extensions.

    I also updated my 2N to a 1 3/8" splined shaft as that is what my buss hog requires.

  • Here is my 1 3/8 female to 1 1/8 male spline. I use it on my 950 to run an 8n flat belt pulley. They are around, just have to look a little harder.
