Analysis of soil reaction forces of a one way disc harrow
Authors: Harrison, H. P.
Description: The one-way disk harrow (O.W. D.H.) has for many years been a very popular tillage tool in Western Canada. The addition of a seeding attachment greatly increased its use fulness and in many areas, it has replaced the seed drill. The implement is manufactured in three basic sizes with approximate cutting width of 12, 15 and 18 feet. The disks are mounted in gangs which move in relation to each other against spring pressure. Six disks per gang with a seven inch spacing is the usual arrangement. Four different disk diamters from 16 to 22 inches are usually available though the 18 and 20 inch disks are the most popular. The O.W.D.H. has experienced many refinements over the past few years with considerable improvement in its performance characteristics. It is evident, however, that some improvements in performance have been obtained by increases in weight of the implement. This is unfortunate, as this increase not only affects the manufacturing cost but also increases the draft and hence, the operating cost due to the added rolling resistance.
