Large-scale gardeners and small-scale truck farmers will want to take a look at this new one-row "precision planter" that mounts behind any garden tractor or ATV.

The ground-driven "Garden Pro" plants everything from the smallest seeds up to small-seeded sweet corn. It's equipped with a seed wheel that can be custom-designed for any seed. The wheel is turned by a gear, and seed spacing depends on the number of teeth in the gear. For example, a 6-tooth gear may result in 3 1/2-in. spacing while a 12-tooth gear may result in 2-in. spacing. Different plates are available. You can also change seed spacing by changing the number of "pockets" in the seed plate.

A pair of large steel discs are used to make a furrow. A depth control wheel mounts next to the discs. Seed is delivered out an "ejector blade" between the two discs. A small packer wheel on back firms soil over the seed.

The planter can't be used to plant larger seeds such as melons, pumpkins, sunflowers, and some varieties of sweet corn.
