In the three-point hitch, the top-link sensing has been widely accepted and is used in mostly plowing. But in rotary tillage, as the tensile force acts on the top-link, the hitch response is not always suitable for tillage.
This paper presents the analysis of hydraulic control by the lower-link sensing in rotary tillage. On this system, the hitch response can takes the draft control and the position control by setting of the feed-back link.
