made two rows of potatoes are planted at once. A 

 hopper is mounted on a frame supported on travelling 

 wheels which, by means of nave-gearing, supply the 

 motion to the working parts. The hopper is con- 

 structed so as to divert the potatoes to the sides. On 

 the axle of the wheel, placed so as to form the outer 

 sides of the hopper, are two revolving cones against 

 which the potatoes rest. Each cone has a series of 

 projections, each of which is fitted with a needle-bar. 

 The needle-bar is fitted with three points ; near the 

 middle of the needle-bar are a stud and spiral spring, 

 and at the back of the cone is a fixed cam which 

 actuates the needles. When one of the projections 

 enters the bulk of potatoes the needle is held back by 

 the cam until a potato is driven up to the projection, 

 when it is impaled on the needle and conveyed to the 

 top of the cone to the spout. Here it is released by 

 the cam, which withdraws the needle until it is flush 

 with the cone, the potato falls into a spout which con- 

 ducts it to the furrow already made by a coulter, to 

 which are attached small adjustable mould-boards, 

 and which is fixed in front of the spout. The dis- 

 tance from row to row can be varied by regulating the 

 spouts or guides to plant from 24 to 32 inches apart, 

 and the distance from set to set can be varied from 12 

 to 16 inches. The machine is arranged to plant either 

 on the Flat or on the Ridge, with or without manuring. 

 A track wheel is provided which forms a groove in 

 the manure placed between the ridges, and thus 

 ensures that the potatoes drop in a line on the manure.
