However, the agricultural implements that are towed by the tractors, such as the sprayers, tillers levelers, and the like are required to be regularly and precisely controlled for efficient interaction thereof with the ground to be tilled, ploughed or leveled. Generally, these agricultural implements that are towed by the tractors are mechanized and as such are powered by the tractor itself.
The tractor provides power and traction that is generally utilized to mechanize agricultural tasks, especially (and originally) tillage but nowadays a great variety of dedicated agricultural implements, such as sprayers, levelers, cultivators, rotavators, ploughs, furrows and the like, may be towed behind or mounted on the tractor for accomplishing different tasks. The term "draft" used in the specification refers to the amount of pull the farm vehicle experiences due to an implement secured to and trailing the farm vehicle, the "draft" can be adjusted by adjusting the position of the trailing implement.Ī tractor is a vehicle used in agriculture or construction and is adapted to deliver a high tractive effort (or torque) at slow speeds. The present disclosure relates to farm machinery, more particularly, the present disclosure relates to a control system for controlling trailer or agricultural machinery hauled by a tractor or a vehicle used in agriculture or construction.
THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED. pdfġ02-US(14)-HearingNotice-(HearingDate-08-02-2021).pdfġ02-Written submissions and relevant documents. pdfġ02-Correspondence to notify the Controller. The (PRV) is actuated by the linkage assembly for regulating flow of fluid inside a cylinder that in turn adjusts the implement.ġ02-DESCRIPTION(COMPLETE)-(19-3-2013).pdfġ02-FER_SER_REPLY. The linkage assembly is functionally coupled to the depth control lever and the draft control lever and is actuated thereby. The housing includes a linkage assembly, a piston-cylinder assembly and a lift arm shaft. The draft control lever is actuated for regulating a draft setting of the implement with respect to the farm vehicle. The depth control lever is actuated for facilitating raising, lowering and maintaining the implement at desired position with respect to the ground for defining initial depth setting of the implement.
A depth and draft control system for regulating depth and draft settings of an implement connected to a farm vehicle includes a depth control lever, a draft control lever, housing, a pressure reducing valve (PRV), and a pair of lift arms.
