With this implement, a man with three horses can cultivate twice as much ground in a given time as one man and two horses can with a single-row machine. 225. Weeders. — The implements known as weeders, one type of which is shown in Fig. 207, are provided with slender, flexible teeth and are used chiefly for culti- vating the soil before the plants are above the ground and for a few days thereafter. They are effective in controlling weeds, which at this period of growth are small and easily killed. 226. Planting im- plements. —

They are effective in controlling weeds, which at this period of growth are small and easily killed. 226. Planting im- plements. — Among the more common planting implements are broadcast seeders, grain drills, corn- and cotton-planters, potato-planters, and transplanters. Broadcast seeders. — The broadcast seeders are employed chiefly for planting grass seed and, to a less extent, small grains. The knapsack seeder is the simplest form. A bag with the bottom opening into the distributing mechanism holds the seed. The bag is held in place by a strap over the operator's shoulder. The wheelbarrow seeder is essentially a long narrow box mounted on a frame and wheel and provided with handles like those of a wheelbarrow. In the bottom of the box are openings that are closed and opened by means of a vibrating rod that engages cogs attached to the side of the wheel when the seeder is pushed across the ground. The horse broadcast seeder, a third type, has much the appearance of a grain drill without the tubes that convey the grain to the ground. The grain is held in a long hopper box from which it is distributed through holes that are Fig. 207. —Weeder.
