I was running my new to me QA-42 down the drive and rolled back my scraper bar. I put a piece of luan under the center to set the dragshoes and apparently there's enough deflection in the scraper and deviation in the concrete. How does a rubber scraper bar work on the blowers and well the blades for that matter.
It would be wonderful if the blowers were designed at a 10-15° offset especially since the shoot is directional.
