I have a contract through a real-estate company and they sometimes give me homes that have grass that has not been mowed all season. I do not like running my new ztr through them, risking my machine. My question is would a walkbehind brush hogg be worth the purchase. I get paid pretty good for knocking this stuff down, plus I can offer this service to other yards that lco's do not want to mess with. What are some good companies that make these?
