a crazy gearbox....



2012/4/30 Stephen Burke

    Hi Ami,

    Thanks for the DWG File and Photo. The design looks good. You have put a
    lot of work into it!

    Reverse is difficult.
    It would be best if you could get a simple gearbox. However
    gearboxes can
    be very heavy and waste power.
    I created an image (attached to this email). You could use a set of
    (more!) pulleys, and twist the v-belt. This combined with a
    tensioner arm
    would allow a reverse option. The v-belt would wear quite quickly
    however
    as it would be twisted against itself.
    It is an idea to think about.

    I hope it helps. If you get any more photos of the tractor it would be
    good to see them.

    Best of luck,
    -steve
