Hi Tyler,
I must have had at least half a dozen of these Sprinters over the time and they have all had this problem. Some I just binned, some I fitted the motors on bigger chassis and I can't recall them still having the problem. Usually with these Sprinters I don't get a catcher so I don't bother with them but I do want to see if it is the lack of weight that causes the problem with these. I still have a couple of them here I can play with, just have to remove the blade boss and fit one that fits a decent type of blade carrier. Another issue with no weight in the spinning mass of the blade carrier is the fact that all the impact load required to cut the grass is being delivered directly by the crank shaft
