I plowed for many years. 6 trucks-4 employees,1 loader and 2 spreaders. Things are different in the "Sue Me State" of NJ. After a knock-down drag out brawl in a driveway during the 96 blizzard- it was commercial only. Residential sucks. People dont want to pay. Commercial is where the money is. You must have insurance, as we have found if someone is to get hurt before the lot is plowed-its an act of God. If they get hurt after you plowed- you are responsible. (Thank the lawyers). Doctors offices, gas stations, grocery stores all have to be open for business. When you go out, you stay out until everything is clear after the snow stops. Always set up written contracts before the season starts. State your charges per accumalation as noted in the local paper, this way no one can feal cheated. Offer salt/sand service if you can. (pretty good money) Always make the customer sign off declining salt/sand service. If someone does sue, you can (sorta) fall back on this. Every truck had the same plow, and spare parts-and the tools to change them. All the equipment was completely gone over in the summer months. Downtime when it was snowing was simply not an option. We had special fans (non flex/clutch) so we could run hiway speeds without overheat, trans coolers, modified auto's, & backup ign boxes in the Fords. Bed boxes were equipped with lights under the lids, all tools incl 1/2" drive were onboard. Trucks were sprung to hold alignment with or without the plows. Everything on the truck was geared toward holding up. The rules were simple-when you take a break-the truck gets a break. Check all fasteners (even the tack welded ones) and fluids at every pit stop. I was charging between 300-400 per hour, per truck. We took plowing seriously and our prices showed. Personally, I would never plow with a new(er) truck, or any make 1/2 ton for heavy stuff. Driveways ok, but not commercially. Have everything in place 1 month before the winter begins, but leave yourself some openings. You will find the amatuers bow out for one reason or another after the first storm- than you step in and take the business. Good Luck-
