Mother Bins vs Field Bins – What’s the difference?

Post Terms

Mother bins and field bins can cause a bit of confusion, as much like with drink sizes, fried potato treats and nicknames for crumbed chicken, Australians have different terminology for each.

What some call Field Bins, the rest of the nation call Mother Bins, (while they call Field Bins “portable grain silos”).

For the purposes of this post, we will refer to Field Bins as temporarily located and portable bulk containers used for the storage of grains and stock feed, and Mother Bins as the towable, on-field grain storage, usually filled from a chaser bin.

While quality brands of both mother bins and field bins are comparable in terms of safety and reliability, they are distinctly different products doing similar jobs, and there are some key differences between them.

What are Field Bins?

More popular in Australia than mother bins, where more on-field storage is typically required. These small grain silos are easily transportable, can be placed in the field where needed, and can be operated by a single person.

While a type of silo, Field Bins are not to be confused with larger transportable grain silos, the more permanent flat bottom silos, or even the smaller sheep and cattle feeders available on the silo market.

Field bins come in sizes from 30 to 37 tonnes, and can be used as grain bins or field bins where on-farm storage is needed some distance away from larger silos or a grain processing facility.

Pros

  • Affordable
  • Single Person Operation
  • Gas Lock Sealed
  • Sight Glasses Fitted
  • Can be used for grain and feed
  • Fitted Auger makes filling and emptying a breeze

Cons

  • More difficult to transport (require multiple tractors or trucks)
  • Typically smaller sizes
  • Must be placed on firm ground

What are Mother Bins?

Not to be confused with chaser bins, mother bins are built to make quick harvesting and transport easy, and are popular in places closer to grain harvesting points. Able to be filled as you harvest, alongside a chaser bin, and can be towed by a single tractor.

While these bins can be easily closed, they are not gas lock sealed, but are capable of holding large amounts of grain – some models of mother bin are built up to 150 tonnes. Their ability to be towed by a single tractor or truck removes the need to keep moving smaller field bins.

Pros

  • Can be towed by one tractor
  • Available in sizes with larger capacity
  • Make transport easier

Cons

  • More complicated moving parts and wheels
  • Not gas lock sealed – shorter term storage
  • More expensive than field bins
  • Used for harvesting only, not feed
