If you were running a family run lawn care service, how old would you feel you children needed to be to help out with. What jobs would you let them do at what age and/or size? Would you let them run any equipment like a push mower, line trimmer, or under 20 horse power rider lawn mower? What jobs would you let them do? I have read the labor laws both for Iowa and the Feds. So I know what the law's say for ages and what they can do.
