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.

Different aspects of the disclosure relate to a device and a method for agricultural soil cultivation with the aid of a soil cultivation unit. The method can include, for example: ascertaining an actual soil cultivation result in a soil cultivation area cultivated with the aid of the soil cultivation unit; ascertaining a deviation of the actual soil cultivation result from a setpoint soil cultivation result; and reducing a deviation of the actual soil cultivation result from the setpoint soil cultivation result with the aid of an adaptation of a rotational speed of a rotatably mounted soil cultivation tool.

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.

An oblique submerged reverse deep rotary tilling device configured to be connected to a tractor. The tilling device includes a stander, a mounted frame, a gearbox and an oblique blade roller. The oblique blade roller has configured rotary blades whose tips bend to the same direction. The angle between the rotary tilling blade roller and an advancing direction of the tractor is 5570 while the rotary blade tips are all toward the right side of the advancing direction. Side force balance blades are installed to the left side of the oblique blade roller, rotate in a plane that is parallel to the advancing direction, and have a rotating center axis disposed at an angle to the oblique blade roller to balance the axial component force of the oblique blade roller.

A system for harvesting nitrogen, comprising a motored robotic litter processing vehicle including an elongate housing creating an inner space for mounting components. A nitrogen harvester box connected to a rear portion of the vehicle is provided including a vacuum canopy connecting four sides to a floor, and wheels. A scoop level to ground having an opening facing the vehicle is enabled to collect litter material including nitrogen. A sieve screen having a mesh size positioned laterally at a height above the floor enables nitrogen particles smaller than the mesh size to fall through the sieve and nitrogen particles larger than the mesh size to be captured on a top surface of the sieve, wherein a vacuum chute collects the particles smaller than the mesh size and deposits them into a collection bin.
