    said first bulk seed container having a first horizontally disposed foot portion at said first side thereof at said lower end thereof;

    said first bulk seed container having a second horizontally disposed foot portion at said second side thereof at said lower end thereof;

    said first bulk seed container having a seed discharge opening at said lower end thereof;

    a second bulk seed container having upper and lower ends, a first side and a second side;

    said second bulk seed container having a first horizontally disposed foot portion at said first side thereof at said lower end thereof;

    said second bulk seed container having a second horizontally disposed portion at said second side thereof at said lower end thereof;

    said second bulk seed container having a seed discharge opening at said lower end thereof;

    a seed handling and dispensing trailer for transporting said first and second bulk seed containers and for dispensing the seed within the containers into planting equipment;

    said trailer comprising;

    a wheeled frame having a forward end, a rearward end, and first and second sides;

    said wheeled frame having a forwardly extending hitch for connection to a prime mover;

    a generally horizontally disposed deck, having a forward end, a rearward end, a first side and a second side, provided on said wheeled frame defining at least a front deck portion and a rear deck portion;

    said front deck portion having first horizontally spaced-apart front and rear hold-down openings formed therein inwardly of said first side of said deck;

    said front deck portion having horizontally spaced-apart front and rear hold-down openings formed therein inwardly of said second side of said deck;

    said rear deck portion having horizontally spaced-apart front and rear hold-down openings formed therein inwardly of said first side of said deck;

    said rear deck portion having horizontally spaced-apart front and rear hold-down openings formed therein inwardly of said second side of said deck;

    said front and rear hold-down openings of said front deck portion at said first side of said deck being aligned with said front and rear hold-down openings of said rear deck portion at said first side of said deck;

    said front and rear hold-down openings of said front deck portion at said second side of said deck being aligned with said front and rear hold-down openings of said rear deck portion at said second side of said deck;

    said front and rear hold-down openings at said first side of said deck being spaced from said front and rear hold-down openings at said second side of said deck;

    each of said deck portions having a seed inlet opening provided thereon;

    said front deck portion adapted to have said first bulk seed container positioned thereof so that said seed discharge opening of said first bulk seed container communicates with said seed inlet opening of said first deck portion;

    said rear deck portion adapted to have said second bulk seed container positioned thereon so that said seed discharge opening of said second bulk seed container communicates with said seed inlet opening of said rear deck portion;

    a first horizontally disposed and rotatable shaft, having forward and rearward ends, positioned below said deck inwardly of said first side of said deck;

    said first shaft extending at least partially between said forward and rearward ends of said deck;

    said first shaft having a plurality of spaced-apart first hold-down members operatively secured thereto for movement therewith;

    said first hold-down members being spaced on said first shaft so as to be aligned with said front and rear hold-down openings of said front and rear deck portions which are formed therein inwardly of said first side of said deck to permit said first hold-down members to extend thereinto;

    each of said first hold-down members being generally L-shaped with first and second ends;

    said first end of each of said first hold-down members being operatively secured to said first shaft;

    each of said first hold-down members having a hook portion at said second end thereof;

    said first shaft being rotatable to enable said first hold-down members to move between a first non-operative position and a second container hold-down position;

    a second horizontally disposed and rotatable shaft, having forward and rearward ends, positioned below said deck inwardly of said second side of said deck;

    said second shaft having a plurality of spaced-apart second hold-down members operatively secured thereto for movement therewith;

    said second hold-down members being spaced on said second shaft so as to be aligned with said front and rear hold-down openings of said front and rear deck portions which are formed therein inwardly of said second side of said deck to permit said second hold-down members to extend thereinto;

    each of said second hold-down members being generally L-shaped with inner and outer ends;

    said outer end of each of said second hold-down members having a hook portion at said outer end thereof;

    said second shaft being rotatable to enable said second hold-down members to move between a first non-operative position and a second container hold-down position;

    said hook portions of said first hold-down members extending transversely with respect to said first side of said deck when in said second container hold-down position;

    said hook portions of said second hold-down members extending transversely with respect to said second side of said deck when in said second container hold-down position;

    said hook portions of said first hold-down members extending in a first direction when in said second container hold-down position;

    said hook portions of said second hold-down members extending in a second direction when in said second container hold-down position which is opposite to said first direction;

    said hook portions of said first hold-down members, when said first hold-down members are in said second container hold-down position, extending over and engaging said first foot portions of said first and second bulk seed containers to secure said first foot portions of said first and second bulk seed containers to said front and rear deck portions respectively;

    said hook portions of said second hold-down members, when said second hold-down members are in said second container hold-down position, extending over and engaging said second foot portions of said first and second bulk seed containers to secure said second foot portions of said first and second bulk seed containers to said front and rear deck portions respectively.
