Some random thoughts...
You can get some hints of the hours on a tractor just by looking at the amount of wear on the clutch and brake pedals and on the foot boards. Also on how much wear in the pivot points and linkages on the pedals. Likewise on the amount of wear on the balls on the lift arms.
Yes the pedal bushings and lift arms can be replaced but often aren't even on a "restortion". And it's tough to fake pedal/foot board wear even on a complete resto.
As to this particular tractor, I happen to know this seller. He's a small dairy farmer in WI and owns several Fords - a Jubilee which was his grand dad's tractor and a 3 cyl 4000 a 4600, 5000, 7600, TW30 and maybe another one or two.
He knows his Fords, works them for a living and if he says he thinks this one is fairly low houred I would tend to believe him.
As to the 134 vs 172 engined tractors, I too kinda prefer the smaller units. The 1958 and later 8/901 and 4000 Priors Are pretty thirsty. More importantly, I've always thought that putting out that much hp (43-45?) on that relatively small platform was kinda pushing their effectiveness. The 34 hp in what is about the same platform seems like a better all round match of hp, gearing, weight and physical size.
And to me putting out around 50 flywheel hp in a 4 cylinder with a relatively light 3 main crankshaft doesn't seem conducive to a long life in the bottom end of an engine. Which brings up
longevity in these things. I'd say Dean is probably correct in his estimate of 2500- 3K hours before needing some attention - valves? rings and rod bearings? all of which can be done inframe. And maybe a full reman at 4 - 4.5K.
(remember that 3 main crank?)
But to keep things in perspective here, that is an awful lot of hours for most of us hobbyists.
You guys know I prefer the 3 cylinder Fords - for several reasons but a buddy of mine has an 841S diesel that I would love to own. It's a little sweetheart and that 4 cyl diesel is SO smooth and quiet compared to my rattley, noisy 3000d. His is the second generation with the crank balancer so should be fairly reliable. And that diesel uses a lot less fuel than the gassers of that era. You still have the issue of a light platform for that much hp but I suspect I could find a use for it if I really tried :)
