System for adjusting the depth of a trench opened by a row unit (10) of an agricultural planter. The row unit (10) includes a trench depth adjustment assembly (90R) configured to modify the trench depth. The trench depth adjustment assembly (90R) includes a depth adjustment body (3044) pivotally connected via a pivot (92) to a frame member (14) of the row unit (10). An electric motor (3030) is operable to cause rotation of a shaft (3034) operably coupled with the depth adjustment body (3044), whereby rotation of the shaft (3034) causes the depth adjustment body (3044) to pivotally move about the pivot (92) thereby changing a position of contact of the depth adjustment body (3044) with a gauge wheel arm (54), thus changing the amount of upward travel of the gauge wheel (50) with respect to a trench opening disc (62) and thus the depth of the trench.

A towed winged agricultural implement comprises a center frame section arranged for mounting behind a towing vehicle relative to a forward direction of travel and a pair of wing frame sections having respective inner ends which are pivotally coupled at transversely opposite sides of the center frame section. The wing frame sections are movable relative to the center frame section between a working configuration extending forwardly and transversely outwardly in opposite directions from the center frame section, and a transport configuration extending forwardly from the center frame section to be parallel to the forward direction of travel and located adjacent the sides of the towing vehicle.

A trench detection system for an agricultural implement includes a row unit configured to form a trench in soil, to deposit an agricultural product in the trench, and to at least partially close the trench after deposition of the agricultural product. The trench detection system also includes a tactile probe assembly behind the row unit that, in operation, contacts the soil after closure of the trench and generates a signal indicative of a quality of the closure.

A plough comprising: a plough body; an actuator mechanism that is configured to adjust a pitch angle of the plough body; and a controller. The controller is configured to: determine an actuator-control-signal for setting the pitch angle of the plough body based on control-data; and provide the actuator-control-signal to the actuator mechanism.

An end wheel assembly for transforming an implement frame from a transport position to a field position is provided. The end wheel assembly can have an end wheel, a wheel pivot rotatably connected to the end wheel, a wheel member pivotally connected to the wheel pivot, at least one attachment bracket attached to the wheel member and pivotally attachable to the implement frame, a wheel actuator to raise and lower the end wheel assembly, and a guide plate. The guide plate can have a channel, a first end connected to the wheel member, and a second end connected to the wheel pivot. The channel can be positioned to receive a positioning member when the end wheel assembly is pivoted downwards and to rotate the guide plate causing the wheel pivot and end wheel to rotate relative to the wheel member and turn the end wheel outwards.
