AN INNOVATIVE Dunstan chaser bin designed to work on 12m controlled traffic systems has taken out the Machine of the Year award at the 2013 Wimmera Machinery Field Days.
It features a hydraulically- controlled swing-up grain table that bridges the gap between bin and header, allowing both units to remain on standard 'tram tracks', greatly reducing compaction.
Previously, chaser bins created additional tracks, as they positioned close enough to headers to line up with unloading augurs.
Dunstan director Craig Miller said the award was a great start to the company's 50th year of production.
"Dunstan was a pioneer in paddock grain handling. It's very satisfying to receive acknowledgement that we're still leading the way," he said.
"Other manufacturers have tried to solve the 12m controlled traffic problem but without any real success.
"The beauty of our solution is that it is so simple. And it can be easily modified to accommodate any header."
Factory manager Chris Barker said there were two significant features in the design.
"The grain table is quite large at around three metres square, to make it easier for the header driver. But the main advantage of the bigger table is that it distributes grain more evenly in the bin. A splitter divides the flow, so that it doesn't all land in the centre," he explained.
"The table angle is also really important to make sure grain flows smoothly. To get that right, while remaining clear of the augur, we had to lower the side of the bin a little.
"The other issue was how to shift the grain across to the other side of the bin. Normally, the augur dumps it in the centre and it flows each way but we had to find a way of moving it."
