It is a sowing device that precisely positions seeds in to the soil
Before the introduction of the seed drill, the common practice was to "broadcast" seeds by hand
Besides being wasteful, broadcasting was very imprecise and led to a poor distribution of seeds
A seedling machine can improve the pre specified rows, distance between plant and planting depth

The shovel soil opener is pushed at an angle into the soil to meter the seed and retain them with the
rectangular bar The soil opener is twisted to make a hole, and the handle is released to let seed drop into the hole. As the soil opener is pulled out the hole is covered with soil The planting operations for the jaws soil opener seeder are as follows The jaws soil opener is pushed at an angle into the soil to meter seed and retain them inside the jaws The handle is pushed to open the jaws and the seed
are dropped & The seeder is lifted to cover the seed with soil
