it erect, there is either an imperfection in the construction of the 

 plow, or it is not adjusted correctly. When a plow " tips up 

 lehind," and does not keep down flat on its sole, or when it 

 seems to run all on the point, either the point is too Hunt, or is 

 worn off too much on the under side, or there is not " dip enough " 

 pitching of the point downwards to the point. Sometimes I 

 have found that a plow could not be adjusted by the clevis so 

 correctly as all the parts were arranged ; and that by shortening 

 the traces or draft chain, or giving them a little more length, 

 it would run like another plow. When a plow is adjusted to run 

 just right, as the point wears off it is necessary many times to 

 give a little more length to the draft chains, or to adjust it with 

 the clevis to run a little deeper. It is sometimes impossible to 

 adjust a plow to run just right with the style of clevis which is on 

 the end of the beam. The arrangement ought always to be such 

 that the draft can be adjusted half an inch at a time, either up 

 or down, or to the right or left. Then if the beam of the plow 

 stands as it should, so that the most correct line of draft will cut 

 the end of the beam, it can be most correctly adjusted in a few 

 seconds. 



457. To make a plow run deeper, raise the connecting point at 

 the end of the beam one or more notches higher in the clevis ; or 

 lengthen the draft chains. To make it run more shallow, lower 

 the draft a notch or more in the clevis ; or shorten the draft 

 chains; or, which should never be done, shorten the lack-hands 

 or hip-straps of the harness. To make a plow take a wider fur 

 row-slice, carry the connecting point one or more notches in the 

 clevis to the right hand. A notch or two to the left hand will 

 make a plow cut a narrower furrow slice. Or, which is seldom 

 allowable, a plow may be made to run more shallow by putting 

 the gauge- wheel lower, (see Par. 459) so as to raise the end of 

 the beam. And a plow may be made to cut a narrower furrow: 

 slice by carrying the handles to the left hand ; or wider by carry 

 ing and holding them to the right, beyond an erect position; 

 neither of which is allowable, except for a temporary purpose.
