The ST-4 Frame Mount is available independently as a skid-mounted system for use on 3rd party implements such as Degelman Harrows.

The polymer tanks are designed to be configured for multiple applications. They will soon be available with liquid fertilizer or pressurized air system upgrade kits. In the case of the liquid upgrade, the ST-4 will have the unique capability to deliver liquid and dry product on the same steerable frame. The pressurized upgrade brings the highly accurate Salford air seeding metering system to the ST-4 and allow product to be delivered reliably to a wide range of implements.
