Just got the study materials for my pesticide license that I'm going to try and get this fall/winter. I currently mow for a large retirement community, who has expressed interest in having me spray for weeds. Looking at a 40 acre site, with about 20 acres of turf. Mostly duplexes set up on a typical suburban type spacing, but ther are over 70 of these units, plus the nursing home and some wide open areas that are yet to be developed. They are currently spraying themselves, but not enough to keep the residents happy. Last round took them almost a week to complete, and I think they still missed some areas. They were using a 25gal pull behind sprayer with a 2-nozzle boom behind a gator type UTV. My original thought was to get a Compact tractor to replace my X720, and use a 40-50 gal 3pt boom sprayer with a 120"+ swath, and do all my mixing on site. I'm not sure if this is the right directon or not. I'm concerned about being able to get close enough to the landscaping without killing off all the shrubs and flowers. I'd like to be able to cover the whole complex in about a day, maybe day and a half. What's my best bet for equipment here? Would a ride on sprayer be able to do something this big in a day? I don't plan on making any purcahses until next spring after I have my license in hand. Just trying to think ahead. Any help would be appreciated.
