The SDI fiberglass 3 Point sprayer is one of the first designs that we brought to market in 1982. Many of those early models are still providing value today, over 30 years later. You have the option of configuring these sprayers in many ways. There are 50, 100 and 150 gallon tank capacities with the option of several PTO driven diaphragm pumps. You can also add a hose reel and spray boom.
