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. - LEONARD TAYLOR.
