We could start emailing you pictures of naked tractors...you know, the sexy stuff like one broken in two for clutch work? Maybe send you envelopes in the mail gently scented with some of that smell good stuff... you know, like transmission fluid. You could let her find a belt in your bed, no, not some other womans garter belt, an alternater belt

. Maybe someone can call you and (if you have a backhoe) your wife can hear you talk quietly on the phone to someone about how silky smooth their wobblestick action is.
Or, you can leave playboy.com open on your browser for her to find when she gets home to make her happy?
