The Dual Bin is a smart investment for the farmer wanting the most out of their machine. Use at seeding time with fertiliser and seed, throughout the year as a sheep feeder to mix grains, and at harvest time to act as a chaser bin. This versatile machine is sure to impress.


Our axles are braked and European made which reflects the top quality and emphasis on safety. The brakes can be plumbed into a hydraulic remote or into the tractors brake kit. This is not an optional feature on our chaser bins, as we believe safety is a standard, not an option! Grain King Dual Bin’s low centre of gravity means safer and easier manoeuvrability for on road transport and in hilly country. The low centre of gravity combined with our standard brakes makes the Grain King Bin the safest on the market.


Grain King Dual Bins have a high resale value due to their reputation for exceptional quality and their ability to stand up to decades of wear and tear in the harshest environments. The Grain King range is renowned fore it’s quality reputation and the Dual Bin is unlike any other bin on the market!


The Grain King Dual Bin is designed for minimal contamination with dual sweep augers that feed a single discharge auger. The bin is split longitudinally with a dividing door that can be opened at harvest time to ensure even grain flow between both sides of the bin. The fertiliser side of the bin also comes with an adjustable auger cover so you can feel confident when filling your air seeder.



Easily control the sweep augers with a user friendly remote control. This wireless remote adds another level of safety and flexibility to a product that could transform your farming operation.


Tandem axles are an option available on Grain King Bins, they are one of the most durable available on the market. They feature heavy duty leaf spring suspension, hydraulic operated brakes on all wheels, rear steering axle (hydraulically lockable for reversing and fast paddock/road speeds), heavy duty axles, and rear steer shock absorbers. This design ensures minimal weight on the tractor drawbar, a low centre of gravity, reduced tractor strain when towing, minimal scuffing when turning, and overall reduced soil compaction.
