Straw blower? Have to admit, I'd never seen one. Around here, for lawn usage, everyone I've ever seen just separates and spreads the stuff by hand. Great for 1/4 acre, but hell for 3 or 4 acres. Many also use factory-assembled straw mats, often woven together with monofilament fishing line, which should be banned, IMO.
Agreed on the peat moss. Not only does it sound like work, but I don't think it's necessarily the best thing for a new lawn. It can improve soil structure and drainage, but there are better products for this.
Very cool. I actually looked at irrigating a few large areas of my lawn, which tend to brown out in our usual summer draught, and have even completely died two or three times in the last 30 years. But the water usage is just enormous when you start looking at providing sufficient water to multiple acres, living off a well. We settle for just irrigating our younger trees and shrubs, and keeping the swimming pool topped up. I think we use ~130 gal/day on tree irrigation + 600 gallons per week on the pool.
