Abstract: Scarifier for deep strip-tillage, that after a single trip allows the soil to be in adequate conditions for planting or sowing, operating with a great energy efficiency, contributing to an improvement in the production environment. The scarifier comprises a plurality of tillage units (a), spaced apart and located parallel to each other, and wherein each tillage unit (a) comprises a support structure (2) on which the corresponding tines (1a, 1b, 1c) are mounted, the lower ends of which are located at different heights, with the depth below the ground (d) being greater toward the rear of the scarifier. The scarifier preferably incorporates a fertilization system.

Abstract: An array (1) of tools for use in planting in combination produce a variety of patterns of operation to provide a required density and pattern of plants. Each tool (6) is provided with an independent sensory/motor system (9) which moves the tool (6) independently with respect to the array (1). A controller (14) in response to a control signal positions the tool (6) automatically in a desired location. The control signal may be an environmental cue such as a region of illumination controlled by the user, or may be a signal generated by a neighboring tool.

Abstract: A support member is pivotally connected to a baler and projects laterally thereof. A side delivery rake is secured to the projecting end of the support member.

Abstract: A support is connectable with an agricultural machine, and a plurality of agricultural tools is provided which are mounted by mounting elements on the support so that they can be adjusted relative to the support. A single arresting element is provided which arrests all of the tools in their respective positions. The tools have mounting portions extending into a passage in the support and either the passage itself or an auxiliary element in the passage has a wedge face to engage the tool mounting portions.
