In one aspect, a system for determining subsurface soil layer characteristics as an agricultural implement is towed across a field by a work vehicle may include a RADAR sensor configured to capture data indicative of a subsurface soil layer characteristic of the field. Furthermore, the system may include a load sensor configured to capture data indicative of a load applied to the agricultural implement by soil within the field, with the load being indicative of the subsurface soil layer characteristic. Additionally, a controller of the system may be configured to determine a first value of the subsurface soil layer characteristic based on the data received from the RADAR and a second value of the subsurface soil layer characteristic based on the data received from the load sensor. Moreover, the controller may be configured to determine a differential between the first value and the second value.

In one aspect, a system for detecting ground engaging tool float for an agricultural implement may include an implement having a ground engaging tool pivotally coupled to a frame and a biasing element coupled between the frame and the ground engaging tool. The biasing element may be configured to bias the ground engaging tool to a predetermined ground engaging tool position relative to the frame. The system may also include a sensor configured to detect a parameter indicative of a current position of the ground engaging tool relative to the frame. Additionally, the system may include a controller configured to monitor the current position of the ground engaging tool based on measurement signals received from the sensor and identify a time period across which the ground engaging tool is displaced from the predetermined ground engaging tool position. The controller may be further configured to compare the identified time period to a threshold time period to determine when a ground engaging tool float event is occurring during operation of the implement.

An agricultural or industrial implement has a main frame including longitudinal and cross frame members. Rear main lift wheels are connected to rear lift wheel arms that are pivotally connected to the main frame and can be raised and lowered using a hydraulic lift cylinder. Each hydraulic lift cylinder is connected to a center pivot of a lug. The lug has a lower connection point connected to a lug anchor, which is connected to a rear cross frame member. The lug also has an upper connection point connected to two load members. One of the load members extends diagonally forward from the upper connection point and connects to one of the longitudinal frame members located to the left of the lug. Another of the load members extends diagonally forward from the upper connection point and connects to one of the longitudinal frame members located to the right of the lug.

An agricultural implement has a main frame including fore-to-aft and cross frame members. Main lift and transport wheels are connected to rockshaft pedestal arms that are pivotally connected to the main frame by way of a rockshaft held by the main frame. The rockshaft is held spanning a distance between upper and lower fore-to-aft frame member components.

A sand bunker rake/infield groomer vehicle having a frame; a plurality of wheels to traverse a driven surface, wherein the wheels are rotatably mounted to the frame; a power source mounted to the frame; and a rear attachment structure attached to the frame, wherein the rear attachment structure provides a joint enabling rotation; a bracket including a shaft wherein the bracket is configured to cooperate with an associated rake/grooming attachment; and a pivoting bracket mounted to the frame.

A device and method for mechanical weed control. The device comprises an agricultural vehicle having a predetermined direction of travel and two opposite longitudinal sides, and a tillage device attached to the agricultural vehicle. The tillage device comprises at least one harrow with at least one tine comprising a tine arm, a tine tip and a tine base, and the tine tip and the tine base are located at opposite ends of the tine arm. The harrow is connected in the region of the tine base to a connecting element, wherein the at least one tine of the harrow has a bend with a predetermined angle and wherein at least the tine tip projects beyond a longitudinal side of the agricultural vehicle and the tine arm is oriented at a predetermined angle with respect to the direction of travel.

In the case of a soil cultivation device with multiple harrow tines, the harrow tines are fastened to levers, which are mounted to pivot on tie bars of the supporting frame via carriers. The operating position of the harrow tines is defined by the levers being adjacent to tie bars, and the harrow tines are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders.
