Abstract
A furrow opener apparatus has a trailing arm pivotally attached to a seeding implement and extending rearward. A packer wheel is rotatably mounted at a rear end of the trailing arm, and a furrow opener is mounted to the trailing arm forward of, and in alignment with, the packer wheel. A bias element exerts a downward bias force forcing the packer wheel downward against the ground. An actuator is operative to move the packer wheel up and down through a range from a lowest vertical position with respect to the furrow opener to a highest vertical position with respect to the furrow opener. A remote control is operative to activate the actuator from the towing vehicle, and a microprocessor is programmed to adjust all furrow openers on the seeding implement by an equal amount when desired.
