[AT] Row Crop

[Al Jones]

Yes, and yes.  The tire would skid slightly on the ground particularly if
you were going from say 52" which was the narrow setting on our 424, to 72"
for straddling two rows.  This skidding was sideways to the tractor because
the tire was literally moving away from the tractor centerline.  Always did
ours on hard dirt--like in the driveway.  We haven't had a need to change
wheel settings on this tractor for years but it was always kinda fun.

Allis and Deere (at least in the 70's-80's) used some kind of wedge where
there was a bolt head sticking out at each rail.  You turned it one time to
the left and it loosened, to the right tightened it.  IH (and I think maybe
Ford??) used the jack screw arrangement--a big nut tightened the wheel
center against the wedge.  The bad thing about the IH version was it was
easy to get the wheel out of center by tightening one or two jack screws
more than the others!

I think there was a horsepower limit to these too, though I have seen BIG
Massey's with spinouts, and they were an option for the narrower rear tire
options on my IH 856--100 hp.
