I just picked up two more condo properties and they are just to big for me to spray with my back-pac sprayer so I had to get this invention off the ground. I have looked at various suppliers and just could not find what I wanted so I made it this weekend. As you can see I made it from a old Toro snowblower that I had sitting in the shop as a back-up in case one of my other snowblowers went down. I have an 8' spray pattern on a 6' break-away boom. I have a total cost of $325.00 into it and I can use it all year round now.
