[AT] Plow question

[charlie hill]

Greg,  this is just a history lesson, not really relevant to the discussion
but A-C made some semi-mounted plows and harrows that would lift
the entire plow or harrow based on load sensing.  They had a hydraulic
cylinder that was controlled by the traction booster and a tail wheel on
the plow or side wheels on the disc that rocked up and down powered by
the hydraulics.  It accomplished two things.  It controlled draft and also
served to transfer weight to the rear of the tractor to increase traction, 
thus
the name "traction booster".  I had the pleasure of running a traction 
booster
tractor new in the late 50's.  The system worked fantastically well and was 
a
pleasure to use.

Draft control depends on the tractor. My JD 4255 and IH 856 have lower
arm sensing; my IH 574 has top link sensing.  I have run semi-mount
plows for 50 years and we have never used the draft sensing.  First of
all, it would only control the front of the plow; second, and this may
vary in other areas, on our land the draft sensing works opposite what
we need. Our land goes from sand to clay.  If set to draft sensing; and
we have tried it, the plow will go deeper in sand and raise when it
pulls hard in clay; just the opposite of what we want as we need it to
stay at a constant depth, not go 12 or more inches in sand and then
raise to 5 or 6 inches in the clay. We always use standard 3 pt. mode
and adjust as needed. If you have the side depth wheel holding the depth
is not too much of a problem. At the present time I am using a 3-18
fully mounted roll-over plow with the side depth wheel. It is heavy
enough that it stays close to the correct depth without touching the
lever. As for raising and lowering, as long as the 3 pt. lever and your
remote lever are close no problem; when you get to the end just raise
the three pt. and a couple of seconds later raise the rear. When you
lower, just lower the front and then the rear.
