Description: When cultivator sweeps or shovel tools are used for deep soil penetration in place of standard mold-board plows, the loads imposed on the cultivator components can be large and, in some cases, may be more than the manufacturer anticipated in the original design. This has resulted in the need for a better understanding of what forces exist under such severe operating conditions so that, if necessary, appropriate changes in design can be made. This paper describes the results of a series of field tests in Alberta over five different and widely separated localities in which the forces were measured on cultivator sweeps, in both a leading and trailing over lapped condition, and on spikes. Numerous investigations into the interaction of simple cultivation implements and soil have been carried out and various two- and three-dimensional mathematical models have been proposed. Much of this data has been obtained in the laboratory under closely controlled conditions and while it has assisted in a better understanding of the mechanisms of cultivation there has been less application to actual cultivator operations including the interaction between pairs of sweeps acting in tandem. With the increased use of the cultivator for primary and secondary tillage, it is suggested that more data be available to enable designers to understand better the actual loading conditions under which these implements are to function
