Amazone has a strong reputation in the mounted spreader world and to boost its accuracy it has introduced Flow Check, which uses sensors built into the hydraulic drive on its larger ZA-TS machines to monitor oil pressure going out and returning.
This helps to monitor any potential blockages of fertiliser coming out of the hoppers. If there is a pressure drop, the system will open and close the offending shutter to try and clear the blockage. If that doesn’t work, it will then notify the operator who will have to grab a shovel.
Weigh cells on the spreader will still control the application rate, with Flow Check simply designed to spot blockages sooner than was previously possible.
