Cevis Is Adjustable.
The clevis is simply hinged. So
that there will be no tendency to pull
the front Of the machine off Of the
ground. and it is also broad enough In
front to allow of the point Of draft be-
ing moved from one side to the other

How to Adjust Chains.
The vertical section between b and
is about twelve inches long. so that
to near will be about four inches
above the ground. This prevents the
pushing of dirt and squares toward!
the plants and allows the chains to
catch them where they lie. The hooks
at and are therefore bent down
ward and somewhat backward through
about five or six inches. Care must be
taken especially in forming the outer
ends l.atW cen c and d, to secure best
results. The downward bend for the
nook at a should not be abrupt. as q
gradual slope helps to prevent catch.
Ing on any obstacles. The hooks at
and e are formed so as to hold tho
chains firmly and yet not interfere
with the passage Of rubbish.
The method of carrying the rear
ends of the outer chains Is shown at
G. The piece k is nearly parallel
with the chains and may be used for
their proper adjustment as to tension
by several holes near the end where T.
is bolted at k. The chains are be-
tween thirty and thirty six inches long.
The stand S. upon which the handles
are pivoted by one-half inch bolt, is
made of a piece of boiler plate ben;
and cut so as to have horizontal tol'
surface about four inches square and
standing about two and one-halr
inches above the draft bar. 10 which i.

The handles are bolted. as at r. tn
