Study on the Draft of the Implements Used in Land Preparation

Abstract

This research was the study on the draft of moldboard plow, disk plow disk harrow. The soil in the experimental field was sandy loam of low moisture content and rather high density. The field had been used for corn planting in the previous years. It was founded that the draft of the moldboard plow was higher than disk plow and disk harrow. The draft was increasing as the speed was up and the ratio of increasing draft of the moldboard plow was very high at the high speed of operation. Weight and shape of the implement were the important factors that involved in the land preparation depth as well as draft.
