I'm thinking about purchasing one of these mowers that seem to be highly rated. The owner says it needs repair, something about the blade coming off and the shaft snapping. I'm wondering if anyone is familiar with this mower and could shed a little light on this. I'm wondering if the mower is destroyed, if the owner hit something hard enough to snap the shaft, there's probably engine damage as well right? Or is it one of those higher end models that is belt driven and the shaft can be replaced? The owner wants $50 for it and it has the bag. I was thinking about buying this for a project and possibly re-selling once I got it fixed up. I'm not sure if it's worth it now.
