I've dethatched in the past with a jrco rake on my mower. Decided to rent a dethatcher this year instead cause I think it will do a better job. I've never used one so I'm wondering how much work is it and does it go pretty fast. Just trying to budget my time out for next week. Most lawns are pretty flat and around 10,000 sg ft each. What can I expect time wise for a 10,000 sg ft lawn. Also when I finish I will just bag the grass with a mower so that part will go pretty quick.
