MaxIV with a 26 gallon spray tank mounted on the rack. The pump sprays 2 gallons a minute with a 15ft fan spray pattern. There are about 10 acres of Phragmites at the Lake Huron shoreline in front of our subdivision. It took me about 3 hours to spray the 10 acres. The invasive Phragmites is taking over the shoreline of the USA, displacing the native species.
