Thank you Sr. for taking the time to do this video. You have just helped me solve my problem. I have 1/2 acre of grass seeds which I don't know how to harvest them. I will be using the blower as a collector of seed. Gracias from Mexico.
If you can, purchase their book shown at the very end of the video. Chapter 14 is titled "Seed Harvesting", and they have extensive tables of when to harvest seed from all the prairie plants". I'm looking at them right now!
