Hello all, I have been using my 94 743B quite extensively this year for snow removal. And have found a few flaws of using this particular machine. The biggest fear of mine is it "walking" away while i'm letting it warm up. When it is really cold the machine has a tendency to creep forward and then start to pick up momentum. Once it runs for a few minutes the problem goes away and the machine will sit still. But it still concerns me enough that I very rarely let it warm up without me in the machine. Is there a way to stop the machine from moving? Other then the parking brake. My parking brake works ok but the machine will still creep slowly with it on. Is there a way to block the hydro pump from sending pressure to the drive motors? Possibly another simpler solution? I would like to be able to start the machine and let it warm up for a few minutes while in the machine and then be able to let it warm up while I'm inside without wondering if its going to join me inside. Thanks!
