lower end of supporting lever 24 rotatably
mounted on the frame of the cultivator. The
vator shields.
The primary object of the invention is to pro
vide cultivator shields of rotary disk type which
are readily adjustable while the cultivator is in
motion from a tractor seat.
Another object of this invention is to provide
cultivators with shields that can successfully be
used in the cultivation of terraces.
Another object of this invention is to provide
cultivator shields that will not hold weeds, trash
or other obstacles which prevent their func
tioning.V
` upper end of lever 24 supports a vertical adjust
ment nut 25 through which passes the threaded
end of an adjusting rod 26.
The rear end of
adjusting rod 26 is supported by a bearing car
ried by a clamping rod 21 that is attached to the
outside lift pipe C1 of the cultivator C. The rear
most end of rod 2B is formed into or attached to
hand crank 28 by which means the cultivator
shields are adapted to be vertically adjusted from
the seat of tractor T while the said tractor is in
