I am in SE CT and we plow some places at the first flake, so our trigger depth is 0" and we stay out to the end. Those are either seasonal or by the hour depending on the customer. We used to be 2" on our regular commercial customers, but have cut that down to 1" for plowing and 1/4" for application of melters to prevent slip and falls. We also go out before the storm and pretreat to keep the snow or ice from bonding to the pavement. If you are interested in this proceedure and what to use to accomplish this, email me at plowking 35@aol.com <br>We can help you bring your snow and ice management into the 22cd century. We also are members of SIMA. www.sima.org<br>They are our trade orginization and if you do not belong, check them out they are 1st class. <br>Anti/de icer applications are the future for us in this business, and education is the most important part of that process. We need an edge on the guys who plow and sand, with the beater trucks, and showing the customers that we have the answeres for their snow and ice management puts us ahead of the competition.<br>Dino
