Claim:
1. A seed planting machine comprising: a seed bin; a rotatable seed dispensing mechanism for dispensing seed from said seed bin; a ground-engaging roller mechanism; and a chain drive transmission system for selectively transmitting rotation from said ground-engaging roller mechanism to said seed dispensing mechanism, wherein said chain drive transmission system includes a lockout clutch comprising an actuator for shifting said lockout clutch between a first configuration and a second configuration, wherein said lockout clutch, in said first configuration, is operable to drive said seed dispensing mechanism in response to said roller mechanism rotating in a first direction, and is not operable to drive said seed dispensing mechanism in response to said roller mechanism rotating in a second direction, wherein said lockout clutch, in said second configuration, is not operable to drive said seed dispensing mechanism in response to said roller mechanism rotating in the first direction, and is not operable to drive said seed dispensing mechanism in response to said roller mechanism rotating in said second direction.
