Disclosed is a ground working apparatus comprising a ground working apparatus having: a frame having a plurality of wheels attached; at least one removable ground working attachment supported directly or indirectly by the frame; a means which is adapted to move the at least one removable ground working attachment between a storage configuration and a ground working configuration; and a vehicle connection means; the apparatus configured such that when in use and when connected to a vehicle via the vehicle connection means movement of the attached vehicle causes the attached apparatus to move in the same direction as the attached vehicle and if the at least one removable ground working attachment is in or is moved to the ground working configuration this results in the at least one removable ground working attachment working the ground it engages with.

A system for tilling compression marks formed in a field by wheels of agricultural machinery the system including a first roller assembly having a plurality of blade assemblies positioned in spaced relation to one another. The first roller assembly rotatably connected to a swing arm which moves the first roller assembly between a disengaged position, where the roller assembly does not penetrate the soil, and an engaged position where the roller assembly does penetrate and till the soil. The first roller assembly is positioned behind and in alignment with a first wheel of the agricultural machinery such that the first roller assembly tills the compression mark formed by the first wheel.

The field cultivating sweep includes a body with wings extending from a center line in opposite directions, and a conditioning element extending downwardly from the wing body. The conditioning element may be a blade extending vertically downwardly along the center line of the body and having a leading edge sloped rearedly from front to back. In alternative embodiments, the conditioning element may have a triangular or rectangular shape or may be in the form of a fluted coulter. The conditioning element acts to till the ground vertically and break up compacted soil as the sweep is drawn along the ground.

In accordance with an example embodiment, a compaction mitigation system for a work area and a method of mitigating compaction in a work area are provided. The method includes determining a compaction map of the work area having compaction data associated with a plurality of reference points, passing a work tool through the work area at the plurality of reference points, and adjusting the work tool at the plurality of reference points based on the compaction data.

Provided is a traveling assisting device for a work vehicle which makes it easy to avoid local compaction of the soil. There is provided a route determination section that determines a target traveling route based on a ground-contact expected area which is an area where the traveling device is expected to contact the ground surface in the field.

One example provides a ride on air injection machine including one or more steerable wheels, a compressed air system providing compressed air, one or more air inject tines to inject compressed air from the compressed air system into the grounds, and a steering system. The steering system includes a steering wheel, a cylinder coupled to the steerable wheels, the cylinder including opposing internal chambers and being moveable to steer the steerable wheels and a control valve assembly to direct compressed air from the compressed air system to the internal chambers and to bleed compressed air from the internal chambers based on a position of the steering wheel to move the cylinder steer the steerable wheels.

Methods, systems and devices for mobile detection of soil compaction and soil characteristic data are provided. Operations include causing a subsurface portion of soil at a compaction detection location to be disrupted using compressed air, generating disruption data corresponding to the disruption of the subsurface portion of the soil at the compaction detection location, generating geographic location data corresponding to the compaction detection location, receiving the geographic location data from the location device and the disruption data from the disruption sensor and associating the geographic location data with the disruption data.

A perforator quick disconnect system for an aerator device includes a perforator and a retaining device. The perforator has a head with an exterior configured to be received within a mounting block of the aerator device and a female component that extends into the exterior of the head. The retaining device has a connector configured to connect to the mounting block and a male component disposed within the connector and moveable relative thereto from a first position to a second position. The female and male components together form a quick disconnect mechanism such that when the perforator and retaining device are received by the mounting block, the male component engages the female component when the male component is in the first position to connect the retaining device to the mounting block and disengages the female component when in the second position to disconnect the perforator from the mounting block.
