is the open wheel. The wheel is depended upon to cover 

 the corn and pack the soil over it. To do this, the open 

 wheel not only offers an improvement over the flat or concave 

 wheels, but is much easier to keep clean. The open wheel 

 has two tires about one and one-half inches wide and set 

 about two inches apart. These two tires are so set as to 

 draw the soil together over the furrow made by the furrow- 

 opener. 



The double-wheel type has two wheels to follow each 

 furrow-opener. These wheels 

 are capable of being adjusted 

 so as to draw the earth over 

 the furrow as desired. Corn 

 planter wheels are made in 

 various heights to accommodate 

 the machine to the varying 

 conditions as they 'may arise. F ig. T^eT" The open and double

Conveniences. There are many devices to be found on 

 the modern planters which are designed to save time. The tip- 

 over seedbox is one. Thus, if it is desired to change the seed 

 in a seedbox for any reason, it is not necessary to pick out 

 the seed corn kernel by kernel. A reel on which to wind 

 the check wire as the last row is planted is another convenient 

 device. There are two general forms of reels in use; one is 

 hung under the seat, and the other is placed on a bracket 

 over the planter wheel at either side. The first location is 

 the most convenient when preparing to reel the wire; but the 

 side location permits the wire to be reeled as the last row is 

 planted, the reeling being in plain sight of the driver and
