IMPROVED INDEXING OF HORTICULTURAL TRAYS

摘要

A horticultural seedling tray (12) made of moulded plastics material and having a plurality of cells (6, 8) disposed in a predetermined array with each cell being adapted to contain a seedling together with a plug of growing medium. The cells (6, 8) in indexing regions of the tray (12) are aligned in rows between opposed front and rear end edges (34, 35) of the tray with indexing engagement means (2) being integrally formed on an underneath side of the tray between two adjacent said rows of cells (6, 8) on both sides of the tray. The indexing engagement means (2) being configured to define a plurality of aligned and uniformly spaced indexing teeth receiving zones (33) between said opposed edges (34, 35) of the tray (12). Also used in combination with this tray is an indexing assembly (21) that includes a drive shaft carrying indexing discs (11) to engage with each aligned group of indexing teeth receiving zones (33).
