Effective Farming 



at a time. 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. 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
