Claim 0:
1. A method for testing a flow of fluid in an agricultural implement, the method comprising:
providing an agricultural flow meter;
providing a system comprising:
a frame carrying:
a filter;
a pump having a pump inlet and a pump outlet;
a pressure relief valve in fluid communication with the pump outlet;
a frame output tube to deliver a flow of fluid from the pump outlet to the agricultural flow meter, wherein the frame output tube has a first removable connection for connecting to the agricultural flow meter;
a frame return tube to receive the flow of fluid from the agricultural flow meter, wherein the frame return tube has a second removable connection for connecting to the agricultural flow meter;
a recycle flow outlet; and
a calibration valve operable between a first position and a second position, wherein the calibration valve in the first position is configured to direct the flow of fluid through the recycle flow outlet, and wherein the calibration valve in the second position is configured to direct the flow of fluid into a container of known volume;
wherein each of the pump, the filter, the pressure relief valve, the frame output tube, the frame return tube, the recycle flow outlet, and the calibration valve are secured to the frame;

connecting the agricultural flow meter to the frame output tube through the first removable connection;
connecting the agricultural flow meter to the frame return tube through the second removable connection;
pumping the fluid from the frame output tube to the frame return tube through the agricultural flow meter to fill the container of known volume;
measuring a time to fill the container;
calculating a flow rate of the fluid through the agricultural flow meter based on the known volume of the container and the time to fill the container;
disconnecting the agricultural flow meter from the first removable connection; and
disconnecting the agricultural flow meter from the second removable connection.
