A tractor mounted tiller/cultivator system that includes right and left swing arms pivotally attached to tractor chassis, right and left cutting head assemblies mounted on the swing arms, each including a right disc motor driving a rotary disc mounted on a distal portion of the swing arm and operatively coupled to the motor. Ground-engaging cultivation wheels surround the rotary disc, and an annular guard prevents unwanted contact of the wheels with vines or trunks of vines and trees. A drive mechanism lowers and raises the swing arms to put the cultivation wheels into engagement and disengagement with ground and to rotate said swing arms about their longitudinal axes. User controls operatively connected to the swing arms, cutting head assemblies, and drive mechanisms enable a user to finely tune the movement of the cutting heads into and out from rows of trees or vines.

The present disclosure relates to a transmission apparatus of an agricultural working automobile, the transmission apparatus comprising: a first gear-shifting part for performing gear-shifting to adjust the speed of an agricultural working automobile; and a second gear-shifting part for performing gear-shifting to adjust the speed of the agricultural working automobile, wherein the second gear-shifting part comprises a sub-gear-shifting drive mechanism for performing gear-shifting, using one operation selected from among an operation transferred through a first power transmission path from the first gear-shifting part and an operation transferred through a second power transmission path from the first gear-shifting part.

A method of operating an implement carrying tillage elements in an agricultural field includes traversing the field with the implement while the tillage elements engage soil of the field, detecting a tillage event based on an operating parameter, recording a location of the tillage event with at least one computer, stopping the implement within the field in response to the tillage event, and generating a first representation of the tillage elements engaged with the soil. The first representation is generated with information from at least one sensor. The tillage elements are lifted to disengage the tillage elements from the soil, and a second representation of the tillage elements disengaged from the soil is generated. The implement is backed rearward through the field with the tillage elements disengaged from the soil, and a third representation of a portion of the soil worked by the tillage elements is generated.

An apparatus for in-situ reconditioning of a media used in an effluent treatment bed is disclosed, in which passage of effluent has become impeded by clogging matter within the media, the bed having been planted with vegetation having roots extending into the media. The apparatus includes a frame supporting a superstructure operable to be disposed above a surface of the bed when in operation, a pair of spaced apart arms having distal ends extending downwardly from the frame, and an agitator extending between the pair of arms and having tines for sub-surface tilling of the media. The agitator is coupled to a drive system operable to cause rotation thereof. A lifter bar is disposed between the arms above the agitator such that when the frame is advanced through the bed the lifter bar passes through the bed below a primary root zone of the vegetation lifting and separating the primary root zone while the agitator tills the media below causing clogging matter to be separated from the media.

A driving head of an electric gardening machine includes a base, a driving assembly, a clutch member and a transmission member. The base defines an axial direction. The driving assembly is disposed on the base and includes a motor assembly and a driving rod. The motor assembly and the driving rod are in a rotation-connecting relationship. The clutch member is sleeved with the driving rod and slidable relative to the driving rod in the axial direction to be in a first position or a second position. The transmission member is rotatably connected to the base. The clutch member is in rotational interference with and engaged with the transmission member when the clutch member is located in the first position. The clutch member is free of rotational interference with the transmission member when the clutch member is located in the second position.

In one aspect, a system for creating a soil compaction map for a field may include a plurality of sensors, with each sensor being provided in operative association with one of the plurality of fluid-driven actuators. Each sensor may be configured to detect a force associated with its respective fluid-driven actuator as associated shanks engage the ground with movement of the tillage implement across the field. Furthermore, a controller of the system may be configured to identify one or more locations of a compaction layer within the field based on sensor data received from the plurality of sensors associated with the detected forces. Additionally, the controller may further be configured to create a soil compaction map for the field based on the identified one or more locations of the compaction layer.

A rotary tiller comprises a frame, a cylindrical drum rotatable relative to the frame, a plurality of tines extending from the cylindrical drum, a motor at least partially disposed within the cylindrical drum, wherein the motor is configured to rotate a motor output member, and a transmission at least partially disposed within the cylindrical drum and configured to engage the motor output member. The transmission is operable to drive rotational movement of the cylindrical drum.

A working machine may work by moving frontward on a ground. The working machine may include: a battery; an electric motor comprising a stator and a rotor and configured to be driven by electric power supplied from the battery; a working unit configured to work on the ground by being rotated about a rotary axis by the electric motor, the rotary axis being substantially parallel to a virtual ground perpendicular to an up-down direction; and a transmitting unit configured to transmit rotation of the electric motor to the working unit. When the working machine is viewed from a front side with the working machine being in a working posture, the battery, the electric motor, and the working unit may be separate from each other in the up-down direction and the working unit may be disposed below the battery and the electric motor.

A soil penetrating apparatus having an automatic tool (e.g., aerator tine) depth control system and method. The system includes an actuator that sets and controls tine depth, a sensor that monitors tine depth, and a controller that controls the actuator in response to the sensor. In some embodiments, the actuator is a hydraulic actuator, wherein once tine depth is set, flow to the actuator is bypassed. A relief may be provided to allow the tines to lift to a shallower depth temporarily when soil hardness exceeds a threshold. The system may then automatically return the tines to the pre-selected depth once soil conditions permit.

In one aspect, a system for reducing variations in the penetration depths between ground-engaging tools of an agricultural implement may include an implement having tires spaced apart from each other. The system may also include pressure sensors provided in operative association with the tires, each pressure sensor being configured for detecting an air pressure within the associated tire. Additionally, the system may include a controller communicatively coupled to the pressure sensors. The controller may be configured to monitor an air pressure differential between a pair of tires based on measurement signals received from the pressure sensors. The air pressure differential may be indicative of variability in the penetration depths of the ground-engaging tools. Furthermore, the controller may be configured initiate a control action associated with reducing the variability in the penetration depths of ground-engaging tools when the air pressure differential exceeds or falls below a predetermined tire pressure differential threshold.
