The first of our new Simplicity 30 Series 14,000L Two Bin air seeders has been delivered! ???? Simplicity Australia machines have long been known for their accuracy and reliability, and this new series does not disappoint. Among many updates, farmers will be pleased that the system can be manually engaged, should an issue arise within the electronic control system, and access to the top of the bin has been improved, with retractable stairs leading to a single-sided walkway that leads one side open for easy fill access.
