The growing popularity of the Seed Spider Planter is lead by its accuracy, reliability, and value. Growers not yet ready for an all new planter commonly use Seed Spider units as replacements for Planet Jr. units on their existing planters.
Seed Spider can accurately plant crops with seed counts from 20,000 seeds per pound, to 800,000 seeds per pound, making it ideal for planting high density crops like spring mix and spinach.
Patented rotating sponge pads gently separate and meter seed without damaging it. Seed rate is controlled by a variable speed electric motor, making adjustments simple. Metering units are available with up to six outlets, and feature quick-release handles for quick and efficient seed changes.
The Seed Spider Metering System is the world's first electronic seed metering system. It's a revolutionary, patented device that accurately meters seed from a bulk hopper to multiple outlets, and is noticeably more accurate over a wider range of seed types than virtually any other seed planter. It's best suited to seeds ranging in size from 20,000 to 800,000 seeds per pound (for example, raw carrot or lettuce seed up to seed the size of a pea).
How does it work?
A 12 volt motor drives a sponge rotor within a vertical cylindrical metering plate. This metering plate has multiple channels in its internal wall, along which seeds are gently separated by the rotating sponge and carried to individual outlets.
The gentle nature of the sponge ensures seeds are never damaged, and a wide range of seeds can be accurately metered; raw and coated/pelleted.
The speed of the drive motor is controlled electronically.
