Abstract
A belt drive arrangement for a cutting implement having multiple pivotally connected decks. The arrangement consists of pulley carrying arms, whereby each of the arms carries a plurality of drive and driven pulleys having respective belts thereon for the transfer of power to the blades carried within each of the decks. Each arm has an end mounted with the deck whereby the arrangement is pivotal to permit the axes about which each of the pulleys rotate to remain substantially parallel to each other as a particular deck flexes relative to an adjacent deck. The belts then generally maintain alignment with the grooves of the pulleys. Consequently, the belts are less stressed as they rotate since they do not have to twist and/or bend when entering or exiting the pulleys.
