LAND LEVELER AND GROWSER ASSEMBLY

Abrégé anglais

ABSTRACT OF THE DISCLOSURE
A frame carries a leveler blade assembly at the
rear end thereof which is supported by a pair of wheels ex-
tending rearwardly from the blade assembly. The wheels are
pivoted to the blade assembly and a fluid operator extends
between the blade assembly and the wheels to raise and low-
er the blade assembly relative to the ground. A growser
assembly is pivoted to the frame forwardly of the blade as-
sembly and can be raised and lowered by a further fluid
operator, relative to the frame so that the depth of pene-
tration of the growser points can be selected. The frame
is adapted to be hitched to a source of power such as a
tractor which also supplies the necessary fluid pressure
for the fluid operators.

Description

B GROUND OF THE INVENTION
This invention relates to new and useful improve-
ments in land leveler and growser assemblies.
; It is desirable to have a combination growser as-sembly and land leveler, the components of which can be in-
; 20 dependently raised and lowered relative to the ground so that
not only can the depth of penetration of the growser points
be controlled, but the leveling and spreading of the loosened
soil can also be controlled insofar as depth is concerned.

: SUMMARY OF THE INVENTION
The present invention consists of a device which
accomplishes these ends and one aspect of the invention con-
- : . .: .

107499~
sists of a land leveler and growser assembly adapted to
be pulled by a source of power including the source of fluid
pressure; comprising in combination a main frame, a hitch on
the front end of said main frame, a land leveling blade as-
sembly secured to the rear end of the frame and spanningsame, ground engaging wheel assemblies pivotally mounted to
the blade assembly and extending rearwardly therefrom, a
fluid operator operatively extending between the blade assem-
bly and the wheel assemblies for raising and lowering the
blade assembly relative to the wheel assemblies, a growser
assembly spanning the main frame forwardly of the blade as-
sembly and means to raise and lower the growser assembly re-
lative to the frame.
Another aspect of invention is to provide a de- ~:
vice of the character herewithin described which is simple
in construction, economical in manufacture and otherwise
well suited to the purpose for which it is designed. : .
With the foregoing in view, and other advantages ~ -
as will become apparent to those skilled in the art to which
this invention relat~s as this specification proceeds, my
invention consists essentially in the arrangement and con-
struction of parts all as hereinafter more particularly des-
cribed, reference being had to the accompanying drawings in
which:

DETAILED DESCRIPTION
Proceeding therefore to describe the invention
in detail, a main frame is provided generally designated 10
which, in this embodiment, includes a pair of longitudinally
extending members 11 which converge together at the front
end 12 thereof and are provided with a conventional hitch
13.
A land leveling blade assembly collectively de-
signated 14 is secured to adjacent the rear end of the main
members
frame/ll and extends transversely and below the main frame
members 11.
This land leveling assembly includes a pair of
spaced apart side plates 15 depending from a front cross

10 ~ 4
member 16 and a rear cross member 17.
A curved rear wall 18 extends downwardly from
the rear cross member 17 and engages the rear edges of the
side plates 15, said rear wall being braced by a plurality
of vertically situated stiffener members 19 illustrated in
Figures 1 and 3. The lower edge 20 of the curved rear wall
18 is the operating edge of the land leveler blade.
A cross shaft 21 is journalled within bearings 22
across the rear of the curved rear wall 18 and wheel arms 22A
extend rearwardly from adjacent each end of this cross shaft.
Ground engaging wheels 23 are journalled for rotation upon
stub axles 24 extending outwardly at right angles from the
rear ends of the arms 22A thus mounting the rear of the assem-
bly upon the ground.
A fluid operator in the form of a ram assembly
25 is operatlvely connected between a lug 26 formed on the
rear of a short main frame member 27 and a lug 28 secllred to
and extending from the cross shaft 21 so that the rear of the
frame together with the land leveling assembly can be raised
or lowered relative to the ground by extension and retraction
of the ram assembly 25.
This permits the lower edge 20 of the blade or
rear wall 18 to be adjusted relative to the ground surface.
The growser assembly collectively designated 29

10'74~
is situated within the main frame 10 forwardly of the land
leveler blade assembly 14. A head frame 30 extends upwardly
from the main frame and spans same. Said head frame inclu-
des a pair of vertical members 31 braced by gussets 32 bet-
ween the members and the main frame members 11, and a crossmember 33 extending between the upper ends of vertical mem-
bers 31. An intermediate vertical member 34 may be provided
extending between the cross member 33 and a cross frame mem-
ber 34Aspanning the main frame members 11.
The growser assembly also includes a cross beam
35 having a plurality of growser points 36 secured thereto
and extending downwardly therefrom in spaced and parallel
relationship as clearly shown in the drawings.
Mounting arms 37 are secured by one end thereof
to the cross beam 35 inboard of the outer ends thereof and
these mounting arms extend forwardly and are attached by
means of pivots 38 to brackets 39 secured to the frame mem-
bers 11.
At least one and preferably a pair of fluid ope-
rators or ram assemblies 40 are pivoted by one end thereofto the cross member 33 of the head frame with the piston
rod 41 being pivotally attached to the cross beam 35 by
means of pivot mountings42 which are conventional.
The fluid operator 25 and the fluid operator 40
.

107499~
are operatively connected to a source of fluid pressure ,
upon the source of power such as a tractor (not illustra-
ted), so that the growser points can be raised or lowered
relative to the frame so that the depth of penetration of
the growser points within the ground surface can be con-
trolled.
In operation, the device is pulled by a tractor
with the growser points engaged with the ground to scarify
same and the loosened soil is then leveled at the required
depth by the blade assembly 14 immediately therebehind, the
depth being controlled by the relationship of the wheel as-
semblies relative to the frame.
:
- Since various modifications can be made in my
invention as hereinabove described, and many apparently
widely different embodiments of same made within the spirit
and scope of the claims without departing from such spirit
- and scope, it is intended that all matter contained in the
accompanying specification shall be interpreted as lllustra-
tive only and not in a limiting sense.
