[AT] Noise Concerns, John Deerre

[charlie hill]

Ralph and John.  I just don't remember the tractor well enough to
be sure and I'm not trying to kick JD.  It could well be that this
tractor was abused.  Some of the help these fellows hired
cared more about smoking pot and drinking than they did about
taking care of equipment so there's no telling.  It seemed to be
working fine the few days I drove it but shortly after I remember
it was in the shop for a long time with some sort of transmission
problem.  I enjoyed running
the tractor.  All I can really remember is that there was a lever,
I think on the right side of the drivers seat near the fender but
I'm not sure,  it worked just like an AC power director.  Push it forward
and it went into a higher range or gear, pull it back and it went back
to the lower gear.  As far as the other gear selection options, I just don't
remember any more.

We had a quad range in the 4430, gave excellent service. The only drawback
was the power assist park release, if you didn't know how to get it out of
park you could break something. We had someone borrow ours once they managed
to tear a reverse gear out of it, claimed it wasn't their fault. We assumed
it was because they didn't know how to get it out of park. Don't think they
asked before they borrowed it.

In the late '80s we were running a sort of prototype plow Deere was wanting
to build to compete with the auto-reset 450 IH plows. The tractor they
supplied was just a tad bigger than a 4020. It had a newer transmission,
believe it was 15 forward gears with no ranges. Once you were moving forward
you just kept pushing the lever to the next gear. Once you got past about
6th or 7th, the front end had a tendency jump. In the higher gears I just
opted to use the clutch.

I think you are talking about the Quad range transmission Charlie. It
was introduced on the new generation
30 series in 1973 I believe. I've never heard anything bad about a John
Deere transmission. Their power shift
  was years ahead of the competition and stood up well. Those 4020
tractors now sell used for more than the
  new price over 40 years ago.
