Abstract

562,026. Tractor-drawn agricultural implements. BROWN TRACTORS, Ltd., D., MERRITT, H. E., and SMITH, A. E. Sept. 1, 1942, No. 12287. [Class 6 (i)] For limiting the working depth of a tractordrawn implement, an adjustable stop or stops on the tractor engages the connecting linkage which is of the type comprising parallel lower links c and a single upper link d. As shown, a tubular shaft g is mounted on a bolt h supported on an inverted U-shaped member i carried on the tractor a. Cams, arms or projections g<1> on the shaft are adjusted beneath the towing- links c by movement of a handle g<5> with a threaded stem g<4> engaging a nut g3 on a crank g<2> fixed to the shaft g. Modifications are described in which a set-screw passes through the end of a lever into engagement with the end of the tractor ; in one case the upper end of the lever is fixed to the shaft f ; in another the lever is pivoted on the tractor and its upper end engages beneath the lever d.
