Older Tractors - adjustable 3 point

I have noticed when looking at older tractors, say 60s, 70s, and 80s era, that the lift link that is adjustable is always on the right side. Is this a correct observation and what is the reason for this?
 
Probably a throwback to the 9N ford....However, all my IH tractors have both sides adjustable.I think most tractors of that era were both sides.
 
It goes back to the Ford of 1939, first tractor in US to have a 3 point hitch. Ferguson had a tractor over in England before that was a Ferguson-Brown. Very few ever made and I dont know if it even had a leveling device or not. But on that 9N Ford the first few did have on both sides but it soon was decided that did not work out as should be as first one would be adjusted down and then in leveling the operator would use the other for leveling untill both would come apart. Also changed lift height before dropping implement to ground when supposed to be raised. Not neer as much chance of that happening with only one adjustable. Now reason for right side, all the plows made for them at that time were right hand plows and for starting a furrow you had to lower the right side so what better place to do the lowering (all the pull type plows had the lever or crank to do that located for the right side as all were also right hand plows) so to keep the operator that was used to controling the level of the plow from the right side why confuse them by putting it on the left? And the location of the right bottom made the right hand lift arm having to move a lot shorter distance than the left hand would to do the leveling why make it so you have to turn the crank twice to get same amount of leveling as one turn on the right side.
 
because you need to shorten the RH side when using a 3pt. moldboard plow to compensate for the wheel in the furrow to keep the plow level
 
My thoughts:

The most common, if not the only time it would be adjusted from a level drawbar would be when plowing. The right side would be raised to keep the plow near level when the right wheel drops into the furrow. The arm would lift up (shorten) to make the adjustment, so the adjusting arm would be on the right side so it would pull together. On left side if it were lengthened it might come apart before desired level were reached.

This would also allow operator to see the furrow and results of changes when adjusting from the seat
 
If you ever have to grade a road, that adjuster is a MUST! Especially when you need to create the crown for drainage.
 
I've recently found out that the world is built for right hand people. If you look a lot of tractors have right hand controls also look at your cars even tools have right hand bevels. If you want fun my right arm is in a sling hydraulic and pto on oliver are on the right only broke 1 shear bolt on the mower so far.
 
(quoted from post at 16:50:52 06/20/16) Left handers are more adaptable, that's why most everything is made for righteys.

.......????...... Sheer force of numbers - 'that's why most everything is made for righteys.' 8)
