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.
