Disc Harrow Requirements
One of the most important requirements is disc blade concavity, that is, correct concavity. Further along we set forth the purposes of disc concavity. We feel it is important enough to devote the extra time and words in a discussion of the subject, because seldom is disc concavity talked about, and very few know that there is difference enough to cause good and bad work.
Eighteen Dollar Harrow
This is the story of a harrow on a budget. I saw plans on the Tillers International website for building an adjustable spike tooth harrow. I modified the plans somewhat to suit the materials I had available and built a functional farm tool for eighteen dollars. The manufactured equivalent would have cost at least $300.
McCormick-Deering Tractor Disc Harrow No. 10-A
Small to mid-sized disc-harrows are a most useful tillage implement. Some farmers consider them indispensable. Discs such as the McD 10-A may be used with either tractors or big hitches of work horses. This tool will cut both plowed and unplowed ground. Ahead of the moldboard plow, the disc harrow is a valuable tool to cut up and free tough sod. When employed in tandem with spring tooth harrows, a great deal of work can be accomplished in much less time.
The State of Horsedrawn Technologies
Within true horse-power circles, where natural partnerships with working animals are embraced and cherished, the family unit is paramount. Tools are being designed today so that a husband and wife with two to four work animals can see their work done. Scale is a defining aspect, going forward and backward.

My rule in all such things, when purchasing at an implement or a seed warehouse, is to ask what tool is in largest demand for a certain purpose, and I usually find that the public in the long run finds out which is the best article, and that the article most in demand is the one usually having the most merit.
