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 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 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.

The present invention 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 two-speed transmission for towed agricultural equipment activated through power take-off of a towing machine comprising an input shaft. A pinion arranged on the input shaft entering into a transmission box activated by the input shaft through a hypoid tooth and/or conical coupling; a crown gear fixed onto an intermediate shaft arranged orthogonal to the input shaft having two different dimension gears. One of the two gears with a clutch is connected to the intermediate shaft, the gears of which being coupled with a gear on an output shaft. The connection of the intermediate shaft/gear of the output shaft without clutch one of the gears has a free wheel connection with the respective shaft. The output shaft is arranged in the same plane as the input shaft and the output shaft is connected at its two ends outside the transmission box with a shredding head.

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, one or more tine assemblies, and one or more hydraulic motors. The hydraulic motors are coupled to the drive wheels and to the tine assemblies. The hydraulic pumps provide power to the hydraulic motors and are coupled to the engine with a toothed timing belt.

An attachable tilling device for a vehicle is provided. The device includes a housing having a base member, wherein a pair of opposing side members extend downwardly from a first end and a second end thereof. A bar member is rotatably affixed between the pair of opposing side members, wherein the bar member rotates about a longitudinal axis. The bar member includes a plurality of tilling blades affixed thereto. A gear system is operably connected to the bar member, wherein the gear system rotates the bar member. A gearbox is disposed on an upper side of the housing, wherein a pair of shaft members are operably connected to the gearbox, wherein a first shaft member connects to the gear system and a second shaft member connects to a motor, such that when the motor is actuated, power is transferred to the gearbox, thereby rotating the plurality of tilling blades.

A connector, e.g. a quick connector, for hydraulic applications, in particular for hydraulic circuits and the like, the connector including a female coupling and a male coupling suited to be alternatively connected and disconnected from each other, wherein the mutual connection of the female and male coupling translates into the possible flow of a fluid between the female and male couplings, wherein at least either the male or female coupling comprises a first detection sensor configured so as to detect working and/or operating parameters and/or values of the connector.
