Hi everyone, just joined the forum in hopes of learning about the tractors my son and I just acquired. Today we picked up a 74 140 H3, a 75 300, two mower decks, a hydraulic front blade, a rear tiller and a box of misc. parts. Both tractors run great and seem to be all original. As far as I can tell, the attachments are in working condition. I just don't know how to install them. I don't know much about these machines so I'll probably be asking a lot of questions. Just wanted to say hi and give a little info. Thanks!
