706 2 point to factory 3 point

[Ilovetractors]

Got a question for anyone. I have a parts 1965 Farmall 706 gas with a factory 3 point hitch on it. I also have an opportunity to buy a 67' 706 gas (cheap and runs great) but with a fast hitch. I'm toying with the idea of putting the 3 point on the fast hitch tractor, just my personal choice. How difficult would the change be? I'm not worried about spending a reasonable amount of time and effort, that's going to be a given. I understand the upper lift arms will need to be moved on the splines, no worries there. Will this be somewhat of a bear or not too bad? Has anyone done this before? Thanks.

Another option for you

Keep the Fash Hitch and

Buy or build lower adaptor arms

Buy or built top bracket

Find a top link or use a hyd cylinder

Looking for answers to the original question, thanks anyway.

It can be done and should be simple. 

Should be.

How long it is going to take is all going to be dependent on condition of the pins and splines that have to come apart.  

Before everything was 50 years old and the pins would slide etc you could probably do it in an hour without any special aggravation.  Maybe they still will and you'll get lucky.

Now if every pin fights you every step of the way maybe it can't be done in a day.  I've had to drive the upper arms off with a sledge and change torsion shaft ends because pins won't come out.

The best thing is that you have the parts to swap if you need them.  Like the front drawbar support if the pin is stuck etc. 

If you're draft ahaft orings leak it would be a good time to go after them.

That's what I was hoping to hear Super_Asepa. I thought it might be fairly doable (somewhat) but like you said, things come apart hard after years or decades since originally assembled but I'm not too worried about it. Going to give it a try if I decide to buy the 706. Thanks for the reply.

Did the same thing with 806. Very easy conversation all parts will switch. To me it’s better than the fast hitch conversation.

Awesome to hear Red666! I dislike the fast hitch myself.

We have done that swap multiple times, with varying degrees of difficulty. As said, the draft pins are gonna be the biggest challenge if they are stuck. I think we only had to re-clock the upper links once and it wasn’t a big deal. Your success may vary…

Clocking the upper links isn't a problem (or shouldn't be)....
When you remove the bolts and washers to remove the upper lift arms, there are two sets of timing marks...if it's got a fast hitch, the timing marks will be at the 2><. 
When you install the 3-pt, simply move the lift arms to the 3>< timing marks. 

There is actually a "2" and a "3" on the end of the rockshaft. Easy peasy.

Sidebar....sort of.

According to my parts book dated June 1966, 806 3pt systems were upgraded starting with Farmall sn 20382 and International 5009. Was the same thing done to the 706?

I have no idea, but a three point can be swapped between a 7 and 8, both 06 and 56 series in any combination. I think, though I have no personal experience, that you can interchange up to a 9 in the 66/86 as well. And I’ve seen at least parts of a 656 three point on an 8 as well, but the sway block that also holds the drawbar is different.

That tells me the 706 was also upgraded. I do know the 756 had a heavier duty setup than 806's up to #20381 because I've seen many examples for comparison. The early 3pt lift arms are the same as on a fast hitch as the part numbers are identical but the later arms and lower link pieces are heavier. Guessing IH figured out quickly that weight demands would increase rapidly for three point work given the system was changed midway through 1965 production.
