Hey all, I have only ever used Toro Powerclear snowblowers at every business I've worked at. Now that I want my own business, I know I want to stick with Toro, and want to know what you use for snowblowers. I've been looking at the 518 zr because its only 54 lbs, easy to load into and unload from a truck bed. A local small engine mechanic suggested the 3650 for commercial use. I'm looking for other options, or opinions on the 2 previously stated snowblowers. Anyone know how heavy the 3650 is? Difference between the 518 and 3650? Other options for commercial use? Thank you.
