I have looked at ads all winter for those Shurflo rechargeable 12 volt backpack sprayers. Does anyone have any experience with one? I use a spray shields sprayer mounted on my grasshopper and carry a hand sprayer for the tight spots.
I use it to apply fungicides to golf greens. I also include Blazon colorant and can verify that the spray pattern is very uniform. There is a constant pressure, therefore a constant rate. The charge lasts for more than 4 tankfuls which is what they say it will do. I bought it from Northern equipment for like $130. Great!
Actually A.M. Leonard has them for $95 www.amleo.com
