  • Patent number: 7757620
    Abstract: A garden machine allows a user to perform various gardening functions with a single machine by allowing the user to easily interchange implements placed on an implement mounting shaft of the machine. The garden machine includes a frame and an implement mounting shaft. The user, faced with a job to do, selects the implements best suited for the job and mounts the selected implements on the implement mounting shaft. The user then manipulates the machine to do the job. The machine can be hand powered or be powered by an engine or motor. A seed drill of the invention includes seed discharge tubes spaced around the circumference of a disk. Each seed discharge tube communicates with a seed reservoir in the disk through a displacement operated valve arrangement. As a planting head is displaced toward the disk against a spring bias, the displacement opens the seed discharge tube so that a seed is discharged from the reservoir into the tube and is delivered to the ground.
