Description
There are several types of seedling/plug planters: Spindle Transplanter, Dryland Plug Planter, These planters are designed to automatically plant containerized nursery stock and can handle seedlings up to 60 cm long.
The Dryland Plug Planter is a trailer unit towed behind a tractor. It is a combination of a leveling device, hydraulic auger with a scarifier, rotating carousel mounted on a movable carriage and two packing spades. the platform is leveled with hydraulic cylinders. The auger digs a hole; the scarifier auger then removes any competing vegetation from around the hole. The carousel containing the seedlings rotates and the carriage moves forward on the platform, dropping a seedling into the hole. The packing spades firm the soil around the seedling. Planting rate is estimated at more than one per minute. Specifications: carousel capacity: 24 seedlings, auger diameter: 7.6-12.7 cm, scarifier: 46 cm, depth: 61-76 cm, power requirements: 52 to 75 kW for drawbar.
Application
The machines plant stock quickly and effectively. Leveling devices and high clearance enable operation on rough ground or moderate slopes, while insuring adequate placement. Auger holes allow for sufficient moisture uptake and unrestricted root growth for better survival.
