Abstract: An agricultural trellis system is provided and generally includes a notch configured to receive a trellis wire therein and selectively release the trellis wire upward during mechanical pruning. The notch can be positioned on an above-ground portion of a vertical line post or a cross arm. The notch can include a tab extending upward from the bottom of the notch, and a first edge and a second edge each formed on the body. The first edge can be a flat edge and can be positioned laterally outwardly from at least a portion of the second edge, which can be a curved edge. The notch can include a retention protrusion extending laterally into the notch toward the second edge to a position where a lateral distance between the retention protrusion and the first edge in a direction normal to the central plane is less than a diameter of the trellis wire.

Abstract: An agricultural trellis system is provided and generally includes an anchor stake configured to extend at least partially into the ground, a mounting plate coupled to the anchor stake, and at least one trellis arm pivotably coupled to the mounting plate. The mounting plate can have a pivot aperture, a first plate aperture, and a second plate aperture configured to position the trellis arm at different angles relative to a plane orthogonal to a major axis of the anchor stake. The trellis arm is pivotable between alignment with the first plate aperture and disposed at a first angle, and alignment with the second plate aperture and disposed at a second angle different than the first angle. A pin can couple the trellis arm to the mounting plate via the first or second plate apertures. In use, the system can have two trellis arms disposed at the same or different angles.
