A hydraulic connector for hydraulic circuits includes a female coupling and a male coupling which are configured to directly couple with and decouple from each other. The female and male couplings do not include inner spaces to accommodate a first sensor. A mutual connection of the female and male couplings facilitates flow of a fluid between the female and male couplings. At least either the male or female coupling includes a first hollow element which is applied directly to an external surface of the male or female coupling to define an inner space. Either the male or female coupling includes the first sensor positioned in the inner space formed by the first hollow element. The first sensor is configured to detect and transmit electronic signals corresponding to working and/or operating parameters and/or values of the connector to a receiver.

An agricultural vehicle transmission may comprise a housing comprising a bulkhead where the bulkhead may divide the housing into a sump and a reservoir. The bulkhead may comprise an opening configured to fluidly couple the sump and the reservoir. A plurality of transmission gears may be disposed in the reservoir of the housing. The opening in the bulkhead may balance the vehicle transmission system to remove excess oil in the sump and away from the plurality of transmission gears.

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 system for rotationally driving ground engaging tools of an agricultural implement may include a rotational actuator configured to rotationally drive a ground engaging tool of the implement about a rotational axis. A controller may be configured to determine a current ground speed of the implement based on data received from a sensor. Moreover, the controller may be further configured to determine a rotational output for the rotational actuator based on the current ground speed of the implement such that the tool rotates at a predetermined rotational speed relative to soil within a field. In addition, the controller may be configured to control the operation of the rotational actuator such that the actuator provides the determined rotational output to the tool while the tool is disposed at a working position relative to a soil surface of the field.

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.

A driveline assembly for equipment, such as a tiller, includes a pair of counter-rotating bevel gears supported on a wheel shaft and rotatable relative to the wheel shaft. The driveline assembly includes a first slider gear movable between a first position in which the first slider gear is engaged with a first bevel gear of the pair of bevel gears, and a second position in which the first slider gear is engaged with a second bevel gear of the pair of bevel gears. When the first slider gear is engaged with the first bevel gear, the first bevel gear becomes operatively connected to a rotatable tine shaft to rotate tines in a first direction. When the first slider gear is engaged with the second bevel gear, the second bevel gear becomes operatively connected to the rotatable tine shaft to rotate the tines in a second direction opposite the first direction.

An agricultural vehicle transmission may comprise a housing comprising a bulkhead where the bulkhead may divide the housing into a sump and a reservoir. The bulkhead may comprise an opening configured to fluidly couple the sump and the reservoir. A plurality of transmission gears may be disposed in the reservoir of the housing. The opening in the bulkhead may balance the vehicle transmission system to remove excess oil in the sump and away from the plurality of transmission gears.

A riding hydraulically driven aerator is disclosed herein. The aerator includes a frame, an engine, one or more hydraulic pumps, one or more drive wheels, and one or more tine assemblies. The one or more tine assemblies may be driven by one or more hydraulic tine motors. The one or more hydraulic tine motors may be directly coupled to the one or more tine assemblies. In various embodiments, the one or more drive wheels are driven by one or more hydraulic wheel motors. The one or more hydraulic tine motors and the one or more hydraulic wheel motors may be driven in series by the one or more hydraulic pumps.

The active coulter system includes a pivotable support structure that vertically adjusts the position of an active coulter component to compensate for changes in the contour of a target field. In the preferred embodiment, a proximity sensor and an associated controller are in electronic communication with a linear actuator assembly. Based on data from the proximity sensor, the controller sends electronic instructions to the linear actuator assembly to automatically move the active coulter component vertically. The system also optionally includes a torque/speed sensor that can operate independently to control the torque and/or power supplied to the active coulter component, or the sensor can interface with the controller and anticipate changes in power needs and increase/decrease power before the operation of the active coulter component is affected.
