New Drive Challenge
One end of the drive needed to operate underwater; standard rubber timing belts and roller chain will perish rapidly if submerged in any liquid. The challenge was to select a product capable of withstanding this environment, yet still transmit the required power at various speeds and loads.

Sudden stops from horses while they are walking (scares) occur often, creating shock loads back through the drive system.
