Experimental study of reclining the cultivator’s paws on spring racks

Abstract

The article describes the results of experimental determination of the trajectories of the toe of cultivator paws on spring racks of three types: light, medium and heavy. The trajectory was determined by loading on the test bench. It is established that the trajectories are non-linear in nature, and elastic displacements lead to the deepening of the toe of the paw, which violates the established depth of stroke. The loading ranges of the racks are defined, under which the deepening does not exceed the limits of agroadmission. The greatest recession was noted in middle racks, the smallest in heavy racks. It was concluded that it is necessary to monitor the recess of the toe of the feet mounted on the spring post.
