Personally, I would not defeat the purpose of the chain guard, but that's up to you. No problem as long as you know for sure that there's no person anywhere around who could be hit by a flying object and no other thing (car, house, etc.) that could be damaged by a flying object. And I guess it would also be OK if you know for sure that your lawn only has grass and nothing else that a blade could throw. I just figure that no matter how diligent I am, sooner or later there's going to be a small rock, nail, short piece of wire, or something similar find its way onto the lawn so that's why I like the chains. And of course even with the chains I don't want anyone else in the vicinity when I'm mowing. Overly cautious? Maybe, but I'd find it hard to live with myself if someone got hurt because I wasn't cautious enough.
