Hey Guys.....Almost Sept 1st, I've grown a bunch and have ventured into the commercial field which is fine by me....This year I'm picking up a spreader, the days of salt/sand powered by armstong (shovel) are over....How do you charge for spreading...my push rates are competitive but have never done bidding on salt/sanding per application....I pay $45 per ton for the salt/sand mixture...possibly cheaper if I buy and mix myself......or is it cheaper to go with Calcium.
