I just recently acquired an older Gravely tractor. It is a Commercial 430 model. It was given to me by a friend who used it to move his airplane in and out od his hangar. The mower has been removed and PTO disabled (I still have to figure out exactly how) It has a heavy weight bolted to the fron for pushing the plane. It runs very well, and I was going to rig a blade for the fron for snow moving (I already have adequate mowage) and the extra weight upfront cant hurt. Please tell me what you all know about it. I will include some early photos. Thanks Guys!
