A boom suspension system may comprise a center frame operably connected to a main frame with linkages configured for vertical movement. A sensor may be operably connected to a pair of boom structures, which may extend laterally outward from opposing sides of the center frame. A controller may be configured to receive input data from the sensor and determine forces or flow rate to tilt cylinders, which may be coupled between each boom structure and the center frame. Each tilt cylinder may be operably connected to a hydraulic circuit, which may comprise a flow control mode and a pressure control mode determined by the controller. The hydraulic circuit may comprise a first set of valves in parallel with a second set of valves. Each set of valves may comprise a solenoid valve in series with a pressure regulating valve and a pressure sensor disposed on either side of each solenoid valve.

Disclosed is a ground working apparatus comprising a ground working apparatus having: a frame having a plurality of wheels attached; at least one removable ground working attachment supported directly or indirectly by the frame; a means which is adapted to move the at least one removable ground working attachment between a storage configuration and a ground working configuration; and a vehicle connection means; the apparatus configured such that when in use and when connected to a vehicle via the vehicle connection means movement of the attached vehicle causes the attached apparatus to move in the same direction as the attached vehicle and if the at least one removable ground working attachment is in or is moved to the ground working configuration this results in the at least one removable ground working attachment working the ground it engages with.

An agricultural row unit includes a soil-engaging tool supported from a pivot arm. A sensor generates an output signal relating to an orientation of the pivot arm relative to a frame member. An actuator is configured to applying a down pressure on the soil-engaging tool. A control system in signal communication with the sensor is responsive to the generated output signal to effect a change in applied down pressure on the soil-engaging tool by the actuator. The soil-engaging tool may be a closing wheel or a flap. One or more additional sensors may be provided on gauge wheel arms of the row unit with the control system being responsive to output signals of the additional sensors to effect the change in applied down pressure on the soil-engaging tool by the actuator.

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 system for adjusting actuator pressure on an agricultural implement includes a fluid-driven actuator configured to adjust a position of a tool of the implement relative to the implement frame, with the fluid-driven actuator defining a fluid chamber. Furthermore, the system includes a valve configured to control a flow of a fluid to the fluid-driven actuator. In addition, the system includes a fluid conduit fluidly coupled between the valve and the fluid chamber. Moreover, the system includes a computing system is configured to determine the current position of the tool relative to the implement frame based on the data captured by a position sensor. Additionally, the computing system is configured to determine a current volume of the fluid chamber and the fluid conduit based on the determined current position. Furthermore, the computing system is configured to control the operation of the valve based on the determined current volume.

A portable pesticide application equipment with accurate application, which includes a pesticide tank. Rollers are arranged at the bottom of the pesticide tank. An inclined pesticide guide plate is arranged below the filter. A side connector is arranged at one side of the pesticide tank. The side connector is connected with a long hose. The long hose is connected with a pesticide discharging device. The pesticide discharging device includes a pesticide control box, two sides of which are hinged with a first iron handle and a second iron handle. A first nozzle is connected with the bottom end of the first iron handle while a second nozzle is connected with the bottom end of the second iron handle. The upper end of the first iron handle is inserted into a first support rod while the upper end of the second iron handle is inserted into a second support rod.

An agricultural vehicle header suspension having a frame, a plurality of supports extending forward from the frame, an anchor plate, a frame pivot joining the frame to the anchor plate to be rotatable about a frame pivot axis, a frame actuator connected between the anchor plate and the frame and configured to resiliently hold the frame at a predetermined position relative to the anchor plate, and to allow the frame to move through a range of motion relative to the anchor plate, upon compression and/or extension of the frame actuator. The frame actuator may be, for example, at least one single-acting hydraulic actuator, mechanical spring, or a pneumatic cylinder.

An agricultural implement has implement settings for soil engaging tools that are controlled based on measured temporal and long-term soil properties in a field. A controller receives data from various soil and optical sensors and provides decision support for adjusting the implement settings. The soil sensors include a square or modified square electrical array that includes two independent, isolated disk coulters running side-by-side followed by two independent, isolated soil engaging runners. One runner has an optical sensor for organic matter, and the other runner has a temperature and moisture sensor. Above-ground optical sensors can be used to measure soil and plant material ahead of and behind the soil engaging tool. The controller can provide real time alerts to an operator that adjustments to the implement settings are needed, or the adjustments can be made automatically based on operator set thresholds, factory settings, or historical individual or global grower adjustments.

A calibration block provides a deck with a slot for receiving a first plate for supporting a distal end of the planter unit when setting its gauge wheels, whereby the first plate is flush with the deck at a predefine distance from the soil. The calibration block also provides a gauge block and associated second plate for increasing the predefined distance.

A control system for a double-acting air cylinder of an agricultural implement includes a valve assembly configured to control a base end air pressure and a rod end air pressure of the double-acting air cylinder. The control system also includes a controller communicatively coupled to the valve assembly. The controller is configured to determine a target base end air pressure and a target rod end air pressure based on a target force of the double-acting air cylinder and a target damping factor of the double-acting air cylinder. The controller is also configured to control the valve assembly such that a first difference between the base end air pressure and the target base end air pressure is less than a first threshold value and a second difference between the rod end air pressure and the target rod end air pressure is less than a second threshold value.
