enables the driver to control the plow by the feet, leaving 

 the hands free to drive. The frame plow with a high lift, 

 footlift, and tongue has many complications as far as con- 

 struction and operation are concerned, but is well worth the 

 difference in price over a more simple plow. Gang plows 

 have the same constructional features as sulky plows, except 

 that two bottoms instead of one are provided. 



The Adjustment of Sulky and Gang Plows. In operat- 

 ing the sulky or gang plow, every effort should be made 

 to have the plow travel straight to the front and to 

 have all of the downward pressure, due to lifting the furrow 

 slice, and the side pressure, due to turning the furrow slice, 

 borne by the carriage of the plow. 

 To do this the point must al- 

 ways be turned down sufficiently 

 to cause the plow to take the 

 ground at all times. No pres- 

 sure should be allowed on the sole 

 of the plow, as this will cause 

 unnecessary friction. All pres- 

 sure as far as possible should 

 come on the wheels, which, with 

 their lubricated bearings, will re- 

 duce friction to a minimum.

 should be set outside of the line of the landside, usually 

 about 1J4 inches. It must also be turned slightly away
