yes 100% agree, you need a blade that is wide enough to clear a path for tires to be in at all times, when fully angled
and also, consider, if your worried about damage to driveway surface, they do make and sell some very good hard rubber.plastic /poly cutting edges that can be bolted on to prevent damage/scratches and such
which could be worth investing in , if you plan to keep a long time
using chains on tires also can damage surface, so, like stated above, adding some good snow tires also can be a benefit if traction becomes an issue('id try things first before getting snow tires)
and another option if you don;'t use skid steer a LOT on hard surfaces past winter, is, you can always MAKE snow tires, or should say make your skid steer tires better, by getting a tire cutter and cutting more edges into your tires you have now, the more edges the better, as its the edges that grab and get you traction, won't add more down force like pure snow tires will, but will gain you some added traction
dis advantage is, they will make the tires wear faster when used on pavement, concrete and likes, not a HUGE amount, but will add some faster wear
tire cutters are not that costly either, and every winter or as needed you can cut new SHARP edges which again are what get you traction, as do snips , you can also cut to help grab on ice! Food for thought!
Steel, rubber, or poly? Which one is best for scraping through ice and snow? There are pros and cons to each.
