IMO, they could both use some work. I think you tried to get too cute with the first one and it looks like lippers. I know your trying to say clippers, but it doesnt work.
The second one looks better but to me says small operation, which you might be and there is nothing wrong with that. From a customers perspective, I would not use a company with a push mower in the logo. Like I said my opinion and Im sure others have theirs. Good luck though, regardless, branding is always a good idea.
