Just took delivery of a brand new 950M with the deluxe seat. Anxiously waiting to use it. I like to keep a spare set of blades on hand and wondering what everyone else uses. Based on suggestions from this forum and research I chose the standard 60" deck. I am mowing about 3 acres, with some trees. So the question is do I stick with the stock blades as my back up set, or go with the Gator type or high lift?
