What is missing in this picture

Shouldn"t this have a 3 hole doo-dad or something.

It"s never been a problem the way it is.
But I recently got a sickle bar mower.
And it hooks to another bracket that hooks to the 3 hole doo-dad.
So is this right in this picture.
Or should I have the 3 hole doo-dad.

I don"t have the special bracket for the SBM.
So I"m gonna have to farmerize something to hook it to.

Thanks.

Trouble with it is if you hang a rock or stump etc it will have too much leverage on the big draft sensing spring and the resulting shock to the internal linkage will bend something inside. Usually just the draft rod at the junction of the offset dog leg in it but sometimes it can even bend the control rod itself.

The Ferguson system lift linkage could not be bent in such a way as it has designs to prevent this happening. Same as the 9N/2N was before Henry decided Harry was making too much money off his invention and decided to steal it. Which he suceeded in doing.

any help would be great

For some reason I can"t seem to post the link.
So I guess you will have to email me for it.

When I got my sickle bar mower (years ago), it did not have the special bracket either. So I made one.

If you can find one on another tractor, and buy it, then life is easy. But if your luck runs like mine, then the quickest way to success is to fab up your own. Here is my receipe:

Take 2 pieces of 3/8" x 2" flat stock about 6" long and drill a hole at the end that will let the long chain fitted pin go through (probably 7/8" diam holes). The holes need to be located just slightly off center so that the new link pieces will fit tightly in the grooves of the rear end casting. These links need to fit a bit snug to the base of your top link mounting where the approx 12" long pin goes through. Put the 2 links in place and hold temporarily. Cut another piece of the 3/8" flat stock about 4" long so that it can sit on the rear edges of the 2 links, and weld the 3 pieces together like a letter "H". Drill 2 more holes (same size as at the top of the H) near the bottom, approx 3.5" on center from the top holes. This is where you will attach the top link of the SBM with a top link pin. The cross piece of the H gives rigidness to the adapter, without it it's just too floppy. The official adapter even has 2 large set screws that make it more rigid to the rear end casting.

What I just described worked well for many years, and enabled me to cut a lot of hay with the 8N SBM.

Good Luck!

That one linkage mite give me problems.
Supposed to have one stabilizer bar on one side
that will "break away" if you hit an obstacle.
The sickle bar will just swing back out of the way.
Then it should reset itself just by backing up.
Don"t know how I could rig up a break-away stabilizer
bar. Mite just have to be extra careful around obstacles.

I would think that the SBM has that link that goes forward beneath the right fender. The link is about 3 ft long, like round pipe with a bracket casting that gets connected to the stablizer bracket held on by the fender bolts. The magic is inside of the casting on the pipe. There is a spring and ball that seats in a partially drilled hole in the pipe. When the SBM hits an immovable object the ball pops out of the indent and the SBM is able to pivot back to about a 45 deg angle. You definitely need this part or else the mower will not stay with the hitch arms, but will always drag back at some angle. If somebody has modified the SBM so that it does not need this link, and can not "break back", then get rid of the whole thing. You can not safely mow without the break away feature. If you hit a big rock or stump, the front of the tractor will be pulled around unexpectedly and out of control, maybe tragically. Other than the belt guard (probably missing), this break away link is the only safety feature this mower had, and it absolutely has to have it!

I saw the linkage but I didn"t understand how it worked.
Thanks for explaining it to me.

HTH,

But mostly I just mow the yard.

Mine is an early 1949 8N.
So that explains why it has the one hole bracket.

Thanks.

It has a 6 foot bar on it.

Been trying to find out how old it is.
And can I still get parts for it.
