Abstract
A foot-operated machine for implanting fastener elements in the ground through an erosion cover on the ground. The machine has a hollow vertical column slidably receiving a vertically reciprocable driver connected to a foot pedal on the outside of the column. A post extends up from the column and carries a top cross piece with hand grips which a person may grasp while standing substantially erect with one foot on the foot pedal. A magazine assembly feeds fastener elements individually in succession into the column to be forced down into the ground when the driver is moved down by pushing the foot pedal down. The magazine assembly has a magazine housing located on the opposite side of the column from the foot pedal, a magazine removably received in the magazine housing and slidably supporting a continuous series of the fastener elements, and a spring-biased follower which urges the fastener elements toward the column. The magazine housing has an access opening enabling manual access to the follower to release it from a lock which can hold it retracted.
