A plow mounted on three or four wheels. Could use one or two bicycle mechanisms (one or two
riders) without the wheels mounted in the front so the weight of the person helps hold down the
whole mechanism. Bicycle parts modified to wind the cable onto a drum. Would take some thought
to get the correct gear ratio. The angle of attack of the plow with the ground would be adjustable, so
that depth the plow penetrates the ground is adjustable. Allows one to pull the plow up to move the
unit to a new row. The wheels are free to turn on the axles and role forward as the cable pulls it.

Battery Powered Winch Plowing
An electric Winch like used on the front of a Jeep could be mounted up front. Batteries located just
behind this. On could sit on as seat above the batters to add mass to the unit or hold it down. Plow
adjustable as describe above. A electric motor with adjustable belt tension drive could be mounted
on one or two wheels to be used to power the unit to the end of a new row. Drive belts relaxed
when cable is pulling the unit. Unless we can come up with a good movable anchor I think one could
build two of these units and have them pull toward each other. Move over a row, move to the ends
and do it again.

Modified Tractor
A farm tractor could be striped down, with an electric motor or modified bicycle mechanism used
as power. The engine could be taken off or striped down, the flywheel used, along with the starter
gear for the interfacing point for the electric motor or human power. The existing transmission (gear
type) would be used in the lowest gear. Beyond this one could use bicycle parts to gear it down
more. Batteries could be charged with a portable (or not) windmill over the long nights.
