Like several of you in the Midwest, we plan to begin our dormant seeding jobs a.s.a.p. Question: Is it safe to use a Toro/Exmark 30" stand-on aerator with tines in the ground while turning? Will the tines be damaged? I've done this in the past & it seems to churn up the soil very nicely. I'm talking about just putting the tines only about one inch deep to prepare the soil/cover the seed. Thinking this might be a good selling point for Toro/Exmark. But will I damage tines? Thoughts?
