Took my blades off today to throw on a fresh set. It's amazing how much debris the scag deck lifts up. I'm not getting the life out of blades with the scag I used to get with the Gravely. The sails on my gravely blades looked as good as new after 60hrs. This is roughly 60hrs on this set from the scag. I know the types of properties can make all the difference in blade life as well as geographically. After experiencing this I'm wondering at how many hours I will begin to see the deck thinning in areas.
