A seed planting machine for dispensing seed. The seed planting machine includes a transmission with a lockout clutch having an actuator for shifting the lockout clutch between a first configuration and a second configuration. As such, the lockout clutch, in the first configuration, is operable to cause the seed planting machine to dispense seed in response to a roller mechanism of the seed planting machine rotating in a first direction and to not dispense seed in response to the roller mechanism rotating in a second direction. Furthermore, the lockout clutch, in the second configuration, is not operable to cause the seed planting machine to dispense seed in response to the roller mechanism rotating in either the first or second directions.
