John Deere 40T Top Speed

Bryce Frazier · Jul 2, 2013

Hi guys it's Bryce, I just finished restoration of my 1954 JD 40T, and am getting ready to road it to a local 4th of July parade. Anyway, here's the question: I have 11.2 x 34's on the back and am wondering how fast this tractor will go in 4th gear? I know that a standard 40 will go about 10MPH, but this is a Tricycle, and the rear tires are much larger. If I had to guess I would say that the tractor will go 14-16, but I don't know. Any help would be greatly appreciated! Happy 4th to all, KEEP IT SAFE!!! Thanks, Bryce

I don"t know exactly, but our B goes a tad over 10mph, our Super C about 12mph and our 40T with the same rubber as both goes faster than eother of them so I assume you are about on the money!
