The Jang JP-1 has two wheels, a handlebar, and a clear seed hopper. As the device is pushed through the soil, it digs a furrow in the ground, deposits a single seed, and covers the furrow, with the back wheel firming the seed. The exchangeable sprockets allow the user to control the distance apart the seeds are planted. The sprockets also come in different sizes to accommodate different seeds.
There is no technical support provided by the manufacturer, users may contact their retailer for support.
