disks will be lifted from the ground by the
action of the rock shaft and the rocker arms
13. When the operating lever is thrown to
the position illustrated in Fig. 1 the disks
5 are brought into engagement with the
ground and each disk is independently
spring actuated to cause it to seek out the
hollows in the surface of the ground and to
enter any water furrows which may have
10 formed to thereby efficiently cultivate -the
entire surface of the -'soil and improve the
stand-of the seed contained within the seed
bed.
This implement is highly efficient not only
15 for harrowing ground preparatory to plant-
ing the seed and for breaking up the crust
of the ground after rains and before the
plants have appeared at the surface but it
is also useful to cultivate around growing
20 plants. It is also especially adapted for
harrowing or cultivating young cotton or
corn, breaking the crust and thus destroy-
ing small-vegetation which pulls away with
the crust and leaves the ground in fine shape.
25 It is also useful in harrowing small grain
that is sown broad-cast. It will break the
crust, cultivate the ground and leave a dust
mulch. which will retain the moisture. It
is a particularly advantageous feature of
30 the present invention that it cultivates in
the furrow as well as upon the tops of rows.
Some types of harrows heretofore used drag
down the beds and cover the furrows thus
dragging. up the plant if it is on a hill or
35 covering it up if it is in the furrow. In
addition, the present structure does not
catch trash to the extent that the old style
harrows catch the trash. Other harrows
heretofore used catch the trash and drag it
40 over the plants, bruising them and injuring
the growth and reducing the stands.
Solid disk harrows are only useful' in pre-
paring the ground for planting. If a solid
disk harrow, is run over growing crops itwill cut up the plant while if it is run over 45
land that has just been planted it will move
the seed out of line in the drill and heave
most of them out on top of the ground.
Disks of the type employed by me will not
cut the plants nor disturb the seed in the 50
drill but will destroy young vegetation that
will pull up with the breaking of the crust
such as grass and the like. Furthermore,
the adjustment secured through the medium
of set screws 28 and the sleeve 27 produces 55
an adjustable under-cut that is particularly
efficient in breaking up the soil.
From the foregoing description it will be
seen that simple and efficient means are
herein provided for accomplishing the ob- 00
jects of the invention but while the elements
shown are well adapted to serve the purpose
for which they are intended it is to be un-
derstood that the invention is not limited to
the precise construction set forth but in- 65
cludes within its purview such changes as
come within the spirit of the appended
claim.
Having described my invention what I
claim is:- 70
The combination with a pull rod, of a
toothed disk having a vertically disposed
shank, a sleeve through which said verti-
cally disposed shank passes, a sleeve dis-
posed at an angle with respect to the first 75
named sleeve and integral therewith, engag-
ing said pull rod means for binding the last
named sleeve in varying positions of ad-
justment around the pull rod and means car-
ried by the first named sleeve for binding 80
the shank in varying positions of rotative
adjustment therein.
In testimony whereof I affix my signature
in presence of two witnesses.
