Abstract: An adjustable toolbar system for an agricultural implement including a linkage assembly configured to be positioned between a main frame of a toolbar and a row unit, an actuator configured to couple to the main frame of the toolbar and to the linkage assembly, a sensor configured to generate a signal indicative of a down pressure applied by the row unit to a soil surface during planting operations, and a controller configured to output control signals to the actuator based on the signal to adjust the down pressure applied by the row unit to the soil surface during the planting operations.

Abstract: The present invention refers to a new adjustment system for mounting and fixing the supports of the planting row units on the toolbars of agricultural implements, which is designed to eliminate possible gaps realized during the assembly and fixing the planting row units on the toolbar. More particularly, the adjustment system is applied to the mounting guides (20a) of the toolbar (20) and is formed by at least one upper mounting assembly (26) and at least one lower mounting assembly (28), which comprise upper (30) and lower (32) support blocks that are associated with said support (24) by fasteners (34), at least one of said support blocks (30, 32) having at least one opening (36) for accommodating an eccentric bushing (38) whose the passing hole (38a) is displaced from the center of said bushing (38).

Abstract: A tow head for agricultural implements, particularly those intended for the distribution of seeds, composts, fertilizers, herbicides, pesticides, or fungicides in the field, is designed to promote a structural reinforcement that heightens resistance and, accordingly, improve the conditions of operation of these agricultural equipment. More particularly, a tow head for agricultural implements is formed by a telescopic center bar from which angularly designed sidebars are projected from the coupling end, and which are connected to the respective side wings of the structural chassis of the agricultural implement, and the sidebars are endowed with a reinforcement that is fixed along at least part of the longitudinal length of each sidebar.

Abstract: A system that includes a wheel carrier system. The wheel carrier system includes a first wheel that couples to a first shaft. A first connector couples the first shaft to a central shaft. A second wheel couples to a second shaft. A second connector couples the second shaft to the central shaft. The first wheel and the second wheel independently rotate and move vertically. A first wheel carrier arm couples to a wheel carrier frame. A first link rotates a ground engaging tool system with respect to the wheel carrier frame to transition the ground engaging tool system from a lowered position to a raised position. An actuator simultaneously rotates the first wheel carrier arm from a first position to a second position and the ground engaging tool system from the lowered position to the raised position.
