| I have taken one seed hose lose and tied a plastic bag to it before, then drive a measured distance and do the math. I have also done the wheel spin method Phred used. Problem there is figuring for any slip, and speed can change the rates. You need a pretty accurate scale to make it work. You can fill the whole drill, put a tarp under it and spin the wheel, that get's you more volume to work with. Generally spin the wheel for 1000 feet. Your arms will be tired!!! | |
