A slip control system for an off-road vehicle includes a control system configured to output a signal indicative of a first action if a magnitude of slippage of the off-road vehicle relative to a soil surface is greater than a first threshold value and less than or equal to a second threshold value. Furthermore, the control system is configured to output a signal indicative of a second action, different than the first action, if the magnitude of slippage is greater than the second threshold value.

In an aerator including a chassis mounted on wheels, a tine depth stop mechanism includes a base mounted on the chassis. A side wall is fixed to the base and has a plurality of apertures therein. A stop arm is movably mounted with respect to the side wall and has an abutment. The abutment has a periphery. A tine weldment is attached to the stop arm, and a tine wheel is rotatably mounted to the tine weldment. A pin passes through one of the apertures of the side wall and engages the periphery of the abutment of the stop arm. Upon a downward movement of the tine wheel, the stop arm moves with respect to the side wall until the pin abuts the periphery of the abutment, thus adjusting a maximum depth of the tine wheel below the chassis.

An agricultural tillage implement includes a frame member and at least one double rolling basket assembly coupled to the frame member. The double rolling basket assembly has a forward basket and a rearward basket behind the forward basket. A horizontal beam is rotatably connected at the opposite ends thereof to the forward basket and the rearward basket. The horizontal beam has a pivotal connection to the frame member.

An agricultural implement system includes a tow bar configured to couple to a hitch assembly. The agricultural implement system also includes a tool bar pivot hinge assembly comprising two pivot points. The agricultural implement system additionally includes a first tool bar member mechanically coupled to a second tool bar member via the tool bar pivot hinge assembly; the first tool bar member extending transversely from the tow bar, wherein the tool bar pivot hinge assembly provides for an axis of rotation of the second tool bar member about the first tool bar member and additionally provides for an extension of the second tool bar member away from the first tool bar member.

A system for re-calibrating a machine includes an arm having a first end and a second end opposite the first end. The arm is configured to be coupled to a frame of the machine and to move within a range of motion during an active state of the machine. The system includes a target element on the first end of the arm, the target element including an outer surface and a projection extending away from the outer surface. A portion of the outer surface defines an eccentric surface along the target element. The system includes a magnetic field sensor coupled to the frame and configured such that the sensor is operable to detect the projection in response to 1) the arm being positioned outside of the range of motion and 2) the machine being not in the active state.

An air spring has an air-spring lobe made of elastomer material, which is clamped at the lobe ends thereof via connection parts between the sprung mass and the unsprung mass and is connected by way of the connection parts to the fastening parts of the sprung and the unsprung mass. The connection parts and the air-spring lobe enclose the working chamber that is under internal pressure and contains the air-spring volume. The working chamber is in connection with at least one air connection provided in the connection parts. At least one of the connection parts is connected to the associated fastening part by a releasable snap-in or latching connection and the snap-in or latching connection includes at least one air connection, to which a feed line or a hose for the compressed air supply is connected.

An agricultural tillage implement with a hydraulic system coupled to actuators of foldable wing sections and to actuators of wheel assemblies associated with each wing section. The hydraulic system having a wing sensor detecting an inner wing section being folded and at least one valve coupled to the wing sensor. The valve being activated by the wing sensor enabling a hydraulic fluid flow to the actuators associated with the wheel assemblies of the wing sections causing the wheel assemblies associated with the wing sections to thereby retract.

An agricultural tillage implement including a first frame configured to be moved in a travel direction, at least one second frame coupled with the first frame, at least one rolling basket assembly coupled to the at least one second frame, at least one actuator pivotally connected to the at least one second frame, and a pressure control system operatively connected to the at least one rolling basket assembly. The pressure control system includes at least one sensor coupled to the at least one rolling basket assembly for sensing a load exerted on the at least one rolling basket assembly by a ground surface and providing a downward pressure measurement signal. The pressure control system also includes a controller in communication with the at least one sensor and configured to control the adjustable downward force applied by the at least one actuator.

By providing an electronic sensor in communication with a hydraulic system for adjusting an angle of smoothing tools of a harrow, the angle of the smoothing tools may be continuously monitored by a controller and/or an operator in the tractor cab. This may allow continuous adjustment of the smoothing tools during a tilling session in order to provide the most aggressive setting for optimum field leveling and residue flow based on field conditions.

By providing a control system in communication with a hydraulic system for adjusting an angle of smoothing tools of a harrow, and a communications system for determining a present geographic location of the tillage implement in communication with the control system, the angle of the smoothing tools can be adjusted according to presently determined coordinate locations on a map which indicates amounts of plant residue. This may allow an automated process in which smoothing tools can be continuously adjusted during a tilling session in order to provide the most aggressive setting for optimum field leveling and residue flow based on field conditions.
