Stupid MF questions

Draft. What is it and what does it do?

Other than draft, what advantage did the Fergusen system give (with respect to 3-point set-ups)?

When Ford II sent Ferguson packing, and Ferguson sued, did Ford have to stop using draft on their tractors and when did patents expire so others could copy and use MF's system?

A friend of mine has a Canadian MF-35 diesel. I just looked at a Canadian MF-135 diesel. What are the differences between Canadian, American and English versions of these tractors? The Canadian MF-135 seemed more heavy duty to me, am I wrong.

I grew-up using a Ford 3000 diesel, about a '66 model. What did MF offer at that time that compared? Was it the MF-135? How do these two tractors compare? If someone had one of each, brand new, stored somewhere and you could buy one or the other, which would it be and why.

This tractor stuff is very interesting! Though I like the old Ford 3000, my friend's MF-35 and the MF-135 really impressed me. I really appreciate your response!

Thanks,
Bill

Others, like Allis, had a somewhat similar system, only theirs was upside down and worked off the main load, and not the top link (or in their case,links) reaction force.

Just when the patents expired, or who paid who what, I don't know. The equivalent to the Ferguson 3 point hitch and draft arrangement got to be widespread by 1960 or so. Maybe somebody at the ASAE may have the detailed scoop.

Others might know the subtleties of the American, Canadian, and English MF's. My understanding is that the English tractors had different diesel engines, at least at first.

The MF 135 probably was the Ford 3000 equivalent, the Massey had some 32 to 34 hp and I doubt the Ford had any more than that.

Back in the mid 60's the Ford and Massey dealers would eye each other at the county fair up home. The Ford people would sneer that the smaller Masseys were just Fords geared down. Life wasn't quite that simple but it probably made them feel better to say it.

I know to get the SN from steering column and engine manifold. My question: Are there different chassie versions, HP etc. of the 135. And does a 135 have a hydrolic spool valve or a way to tap a source to add one? Thanks for any assistance...Rich
