That snow plane looks like fun...similar to the air boats we use down here...
Was that Bolens 'snow tractor' in the first post designed to tow other attachments?...similar to turn of the century field tractor designs where the operator was seated on the implement being towed instead of the tractor itself...
These tractors were designed for farmers to replace the horse with a simple engine powered tractor, but still be able to use their existing implements (plows, harrows, etc.), and not have to upgrade all at once...
Such an unusual design for the mid-century, as in this Bolens machine...
