A grading implement features a frame with at least one movable section carried by a main frame section. Each movable section is movable relative thereto between a storage position and a working position reaching further laterally outward from the main section to increase a working width of the implement. An underside of each movable section features a respective blade adjustably mounted thereto for selective adjustment between different relative blade positions relative to the movable section. One embodiment features outboard blades on two movable sections, inboard blades on another two movable sections, and a rear blade mounted centrally on the main section behind the inboard and outboard blades. A dust suppression system features spray nozzles distributed across the main frame section behind the blades, and storage tanks mounted atop the main section so that weight of the dust suppression agent provides extra downforce to the blades.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

Described herein are implements, systems, and methods for applying stress to agricultural plants of agricultural fields. In one embodiment, an agricultural implement comprises a frame transverse to a direction of travel of the agricultural implement and a stress mechanism disposed on the frame in operation such that the stress mechanism applies a force to the row of plants as the agricultural implement moves through the field.

A tractor includes a working motor, a work machine including a roller configured to rotate by an output from the working motor, a support mechanism configured to support the work machine such that a working posture and a retracting posture are achievable, and a control device. The control device executes: an adherence amount acquisition process of acquiring an estimated adherence amount as an estimated value for the amount of mud attached to the roller; and a mud removal process of, when the estimated adherence amount is equal to or more than a determination adherence amount, removing the mud from the roller by driving the working motor in a state where the work machine takes the retracting posture.

An agricultural tillage implement includes a main section including a hitch extending in a travel direction, a plurality of foldable wing sections coupled with the main section, a plurality of ground engaging tilling elements, a plurality of wheel assemblies and a control system. The tilling elements are coupled to the main section and wing sections. Each of the wheel assemblies include an actuator. The wheel assemblies include a first plurality of wheel assemblies associated with the main section and a second plurality of wheel assemblies associated with the plurality of wing sections. The actuators of the first plurality of wheel assemblies being independent of the actuators of the second plurality of wheel assemblies. The control system is configured to actuate the actuators to effect a profile minimizing operation of the foldable wing sections when the implement is being transitioned into a transport mode.

The press wheel has instrumentation associated therewith detecting a rolling of the wheel over a planted set. A computing device is connected to the instrumentation and to the speed monitoring device of the planter. The computing device determines spacings between planted sets. The data obtained is real-time data and is readily available to the operator of the planter so that the speed of the planter can be adjusted on the fly to maintain an ideal set spacing. The press wheel has a soft, smooth, flexible and stretchable rolling surface capable of deforming over a planted set and detecting an imprint of the planted set in the surface thereof, without damaging the planted set. A contact signature of the rolling of the press wheel over a planted set shows that the rolling on of the press wheel over a planted set is as smooth as the rolling away from the planted set.

A remotely positionable stabilizer wheel arrangement for a towable agricultural implement utilizes an electronic control unit that receives an input signal indicative of a desired position of the stabilizer wheel, and/or a desired depth of penetration of tillage tools operatively attached to the front and rear of the implement frame, to automatically control an electrically powered linear actuator of the remotely positionable stabilizer wheel arrangement to position and hold the stabilizer wheel at the desired position of the stabilizer wheel.
