Movable Field Bins Coming to North America


Movable field bins or “mother bins” are used in Australia to alleviate bottlenecks in grain movement off the field at harvest. Rather than waiting for a truck to arrive, a grain cart or combine can dump into the mother bin at the end of the field, and vice versa — a truck doesn’t have to wait for the grain cart if there’s enough grain for a load in the mother bin.



Several companies have pursued bringing the concept to North America, including Demco, who recently announced its taking orders for its 3,000 bushel Harvest Link for the 2016 harvest.

Demco’s unit (56′ long, 12′ wide and 12.5′ high) rests on a steel frame when in the field and is raised for transport. The 36′ auger and gates are operated from the tractor PTO and hydraulic system, with a joystick control in the cab giving the operator the ability to load a semi without moving it. The Harvest Link also features a scale system in which the weight to be loaded onto each truck can be programmed to avoid over-filling.

The company says the Harvest Link can also minimize truck traffic on fields, as the long auger can reach across a road ditch to fill trucks on the road.

What do you think? Would adding more grain storage capacity in-field make your harvest more efficient? Would you rather use a bigger (and more mobile) grain cart? Feel free to share your thoughts in the comment section below.

Wheat prices jump into August — This week in the grain markets

This week, winter wheat prices touched a three-year high, but it didn’t last. Chicago SRW wheat prices for September 2018 gained 5 per cent or about 26 cents US/bushel to close at $5.56. While the December 2018 contract was up 5.4 percent — or nearly 30 cents — to finish a tad under $5.80. In…Read more »

Interesting concept. I would love to see some data on how it helps harvest effecicy or reducing soil compaction. Can’t imagine it’s cheap. Next to the 100k Grain cart and another tractor it seems like a “i have it” item.
