What is claimed is:—
1. A dam forming attachment for wheeled
llsters comprising a beam pivotally connected to
the lister for swinging movement in a vertical
plane, a scraping element mounted on said beam
and adapted to travel in the ditch made by the
lister plow, and means operatively connecting the
beam to one of the wheels of the lister for period
10 ically "lifting said element out of the ditch, said
means including a shaft rotatably mounted on
the lister,'an arm projecting from said shaft, a
mounted on the second named beam, altr'ans
verse, inclined scraping disc mounted on said _
shank and adapted to travel in the ditch left by
the lister plow, a trip mounted on said one wheel
of the lister and engageable with the lever for
‘swinging the arm forwardly, and a chain con
necting the arm to the second named beam for
periodically lifting the scraping element out of
the ditch.
3. A dam forming , attachment for wheeled
listers comprising a pair of bars pivotally con
nected to the lister beam on opposite sides thereof
?exible member connecting the beam to-said arm, - for-swinging movement in a vertical plane, a
a lever projecting from the shaft, and a trip on
15 said one wheel engageable with the lever for actu
ating the ‘shaft and the arm-in a direction to lift
the beam.
_2. A dam forming attachment for wheeled
listers comprising, a pair‘ of transversely aligned
beam rigidly secured between said bars, a scrap
ing element mounted on the second named beam
and adapted to travel in the ditch left by the
llster plow, a rod secured between the bars and
extending upwardly and rearwardiy therefrom,
an arm mounted for swinging movement on the
20 bearings mounted on the rear axle housing of the . tractor, a chain connecting the second named
lister adjacent one of the rear wheels, a shaft beam to said arm for lifting the scraping element
journaled in said bearings, an arm on the inner out of the ditch, said chain being secured, at an
end of said shaft, a lever on the outer end of intermediate point, to the rod for forming an
the shaft, a pair of bars pivotally secured to the angle in said chain, and means operatively con
lister beam on opposite sides thereof for swing necting the arm to one of the wheels of the trac
ing movement in a vertical plane, a beam rigidly
secured between said bars, a shank adlustably
tor for periodic actuation thereby.
