[AT] Plows, was Re: Supervision

[jtchall at nc.rr.com]

Buddy of mine came by yesterday morning, he used to work on the farm that 
ran the semi-mount behind the 1466. It was a 5 bottom and pretty certain it 
was a 720. The owners only complaint was having to remove one of the duals 
for plowing. He said the owner wished he would have bought a different 
configuration hitch that would have allowed him to leave the dual on.

What little plowing I ever got to help with was done in the summer. We never 
had a problem with the 450 plows choking up. Considering we had two of them 
makes me think they were the "holy grail" of the plowing world at that time. 
Prior to those we had various horse/mule plows,disc and bottom plows for the 
Farmalls, and one or 2 Deere bottom plows. Basically all the farms around 
here that plowed were running 450's, regardless of the color tractor pulling 
it.

I've often considered why it is my area plowed so deep. I guess it is due to 
soil type, our land can pack pretty darn tight. I guess plowing was the only 
way of getting into the hard pan easily. Folks had subsoilers, but they were 
slow and expensive to run. We had a two shank we ran behind a 4430 Deere 
(about 115hp?). At times that was all that tractor wanted. I never ran it 
but have told it was bad on breaking shear bolts, sometimes 2-3 bolts in a 
couple hundred feet. In the late 70's chisel plows got real popular here and 
I think that is what began to park molboard plows. V rippers were around for 
a while in the 80's, primarily with tobacco farmers. Again they were very 
expensive to run and those guys got the best return for their effort.

The 720 plow was a newer version of the 450. It came as an automatic
reset or a toggle trip (had to back up to reset bottom) .  The big thing
about this plow, at least in our area, was that it had the best trash
clearance of any plow around, and most were sold with 18 inch bottoms.
They also pulled fairly easy and did a very good job of turning the
ground. They shined best in corn stalks. Earlier they made a 710 which I
had once; a real piece of junk, it plugged real often as it had poor
clearance and the tail wheel ran on top of the ground instead of in the
furrow making depth control very hard. Everything wrong with the 710 was
corrected on the 720 and then some. If you google 450 and 720 plows they
have some pictures of each to look at.
