[AT] plows

[joehardy]

Bruce, After reading your e-mail about the plow info from your John Deere 
book, I went to my book shelf & found two different copies that I had saved 
from my wife's homestead. I have a copy of the 9th and 25th editions of " 
The care, operation, and repair of farm machinery". Its too bad that 
publishing dates are not included! The 25th edition describes deep-tillage 
farming. It shows a single wedge pointed device working at depts of 10" to 
36"which just is breaking up the sub soil. Behind this wedge is a thing 
called a mole-ball; a torpedo-shaped steel ball which opens a tunnel through 
which the water could flow and drain. The 25th edition shows both rubber 
tire , gas & diesel & crawler tractors. Also notes of interest: One ton 
liquid manure contains 40% of plant food. One inch of rainfall means 100 ton 
of water on every acre. Well enough info for tohight!

Someone out there asked about the types of plows.
I just found my grandfather's book on- The Operation, Care and Repair of 
Farm Machinery-
thirteenth edition- published by John Deere=
there is no date of printing, but much of the equipment is horse drawn, the 
tractors shown as John Deere's are "the General Purpose Tractor" to handle a 
four-horse load, and a
"Standard type" to handle a two-horse load (looks like an LA).
This book lists 6 plow styles: Prairie breaker, Stubble bottom, General 
purpose bottom, Slat moldboard bottom, Black-land bottom, & deep tillage 
bottom.
