<p>The leaf harvester has a blower supplied from a header with a blower channel on the blower pipe connection to take away the leaf. On the longest portion of its conveying section, i.e. between the blower pipe connection and the ejection section, the blower channel (4, 4') is roughly closed. On its underside, its has collection and guide faces(6, 6', 7, 7') for joice, fine leaf shreds etc. It also has a drop opening/drain(8', 8). The blower channel (4) in its complete length has a tubular cross-section with a bottom slot of width which amounts to one third of the blower cross-section.</p> |
