An aerator device. The aerator device includes a manifold including an interior channel, a connector aperture, and a plurality of nozzles configured to discharge a pressurized fluid stream. A cover plate is disposed on an upper side of the manifold. A first connector includes a first open end in fluid communication with the interior channel and a second end extending through a connector aperture disposed on an upper side of the cover plate. A second connector is configured to receive a hose connection to a pressurized fluid supply. A wheel including a wheel height adjustment mechanism is affixed to each side portion of the cover plate. In one embodiment, the manifold is configured to rotate when the wheels of the device rotate via a drive roller. A handle extending rearwardly from the cover plate includes a trigger mechanism configured to activate the flow of fluid from a pressurized fluid source.

A vehicle-assistance system for classifying objects in a vehicle's surroundings. The system includes: at least one memory configured to store classification information for classifying a plurality of objects; and at least one processor configured to receive a plurality of detection results associated with light detection and ranging system (LIDAR) detection results, each detection result including location information, and further information indicative of at least two of the following detection characteristics: object surface reflectivity; temporal spreading of signal reflected from the object; object surface physical composition; ambient illumination measured at a LIDAR dead time; difference in detection information from a previous frame; and confidence level associated with another detection characteristic. The at least one processor is also configured to: access the classification information; and based on the classification information and the detection results, classify an object in the vehicle's surroundings.

An automated planter device for planting seedlings in an obstacle-strewn and/or uneven terrain. A laterally extendable boom is located at the end of a vertically-moveable arm, which arm may also be swung from side to side. The boom has a plurality of spaced-apart seedling injectors thereon for planting seedlings. Advantageously, due to variably adjustable positioning of the seedling injectors on the boom, obstacles encountered such as tree stumps or medium sized rocks capable of being traversed but which otherwise create an obstacle to a typical seedling planter, may be avoided. The seedling injectors are each coupled via vacuum hoses to a bin mounted on the planter, which vacuum hoses supply seedlings from the bin to the injectors. A powered gantry at the rear of the planter unloads the bin from the planter when empty, and engages and lifts a re-stocked bin containing additional seedlings onto the rear of the device.

A planting apparatus of nursery tree includes an auger, a guide member having a hollow tube shape, a blade member, sliders, and motors The auger, the guide member and the blade member form the nested structure of the three-layer which are centered upon the auger, and the auger and the blade member are rotation members rotating on the same vertical axis line. By such a constitution, desired planting hole can easily be excavated, and the ground around the excavated hole and a root clump of the nursery tree can be leveled, covered and pressed by the blade member without forming a gap while holding the nursery tree by the guide member not to be inclined.

A control system for controlling the depth of an opener device in an agricultural planter comprises a gauge wheel on a pivotably mounted support arm, a mechanical element coupled to the support arm to move in response to changes in the angle of the support arm, a sensor adapted to measure changes in the relative elevations of the opener device and the gauge wheel to produce an output signal representing the current relative elevations of the opener device and the gauge wheel, and a control device receiving the output signal from the sensor and producing a second output signal for maintaining the opener device at a selected elevation relative to the gauge wheel.
