 Clevis Is Adjustable.
 The clovis 0 p is simply hinged, St that there will be no tendency to pull the front of the machine off of the ground. and il is also broad enough ln front to allow of the point of draft be- ing moved from one side to the other, so that the front of the machine may be thrown closer to one row if desired.
 The front guard on each side, a | d, is made of one piece of spring steel seven eighths by three-sixteenths ly strong and best adapted to carr! the tension of the chains d while still yielding to the pressure against the bases of the plants as they may strike the outer sloping ends near The inner ends of these guards D are horizontal. about eighteen inches each in length. and serve to carry the front guard above the draft bar n III and. passing through the keeper O. guide in the adjustment for width, The machine cannot be extended De voud the bent ends at a or closed be yond the angles at D.
 How to Adjust Chains.
 The vertical section between D anti Is about twelve inches long. so Una! the remainder of the front guard rom c 10 near d will he about four lnche3 aboye the ground. This prevents the nushinc of dirt and squares toWaro the plants and allows the chains 'o catch them where they lie. The hooES at q and are therefore bent down ward and somewhat backward through about five or six inches. Care must ne taken especially in forming the ou'eF ends between and q. to secure oeS' results. The downward bend TOT 'h" nook 9t q should not be abrupt, as Il
 gradual slope helps to prevent ta'eii :.
 tna on any obstacles. The hooks az
 and are formed so as 10 noia tue chains firmly and yet not lnlefle'' with the passage of rubblsh
 The method of carrying the rear .,as of the outer chains Is shown az h q The piece k l is nearly paralie' .,;+, the chains and may be used fo' tbeir proper adjustment as to tension hy several holes near the eho wne'1 a' ,s holted at k The chains are De .5,on thirty and thirtysix inches long a,,,,, stand S. upon which the hanaieS

 Handles Adjust Chains.
 rh,. handles are b0Ited. as at r. to he heavy pieces of iron (about two D! ,ne half inch tire steeD, which are ,ent to receive them just behind the ,ivotal point at X. at such an angie aS q bring the handles to the propei ,eight and position. In front or hese pieces bearing the handles npco ot be so heavy and may therefore p's apered and welded to smaller steer unninc forward to b. where it ls ol.ed to the front guard. The opera lon of this arrangement is similar to hat of a huge pair of shears. When he handles are pushed apart the front f the machine is spread wider.
 The braces j e serve to support strengthen and carry the front guard They are riveted to the adjusting irons if I. one above and one below the shear" pieces. to prevent their inter- 'erence with the closing of the ma .hine At this iron is bent to con 'orm to the front guard, to which II s riveted leiwe and l. at which point 1t is bent downward and forms he hook e
 Made of Tire Steel.
 Ordinary tire steel about one by one 'ourth inch may he used for all parts ike the clovis Q D. rear arches Il m md b g and braces k l and The front guard b ( d should be II oDt AuE otCci. tS Si'C' '> iA'> ' reads on the front guard should be 'ound and fit smoothly. In nearly all other places the irons are fastened to ,ether by one fourth fn''h square head d bolts, with washers as needed
 Although t',e chain cultivhtor was designed priI larily for bringing the squares to tn mddleS, if was found n field pract q "a have a most im- ,ertant cultul l effect.
