4 years ago I got an opportunity to take over an existing mowing contract from a guy who had to stop, for a 66 unit condo. Last year I lost my full time job and decided this may be the time to go full time and expand. Spent fall and winter studying and getting my PCO license as well as looking at this site for education and advice. I have an opportunity to bid on the weed control and fertilizer business for a couple of new properties. I have a 60" Exmark zero turn, 48" walk behind, Stihl trimmers and blowers, so pretty good mowing equipment. I have a 25 gal. Brinley tank sprayer with a 48" boom and hand sprayer attachment. I realize this is not "big guy" equipment, but it's what I can afford right now. My question is this: The properties I'm looking at are all around 4-5 acres. Is there a quality liquid pre emergent and fertilizer that I can use with the equipment I have? From what I've seen granular seems to be, for the most part a better product, especially for the pre emergent. I know the equipment is small but the properties are too. If absolutely necessary I could buy a tow behind granular spreader, but I'm on a shoe string budget right now. Can I do a quality job with the equipment I have or am I out of my league?
