EXPERIMENT STATION BULLETIN 449 siderably fewer B grade and cull potatoes were obtained from the plots on which the fertilizer was applied all banded than from the other plots. Potato Vine Lifters. (Karol J. Kucinski.) When potato vines become large enough to cover the space between the rows, the moving of spraying equipment through the field crushes the vines, thus causing a decrease in yield. An im- proved vine lifter has been developed which will pick up the vines from the space between the rows and push them back into the rows. This allows the passage of the wheels of both the tractor and the sprayer without injury to the plants. The lifters were patterned after those developed by John W. Slosser, Engineer, Research Division ot the Soil Conservation Service, in cooperation with the Maine Agricultural Experiment Station. Certain modifications of the basic design were made to improve the operation and utility of the lifters. Each lifter is attached to its control by means of a clevis and pin coupler to make its removal from the tractor easy. The vine lifters for the tractor rear wheels are suspended from the arms which usually carry the cultivators and can be operated hydraulically. The vine lifter for the front tricycle wheel is suspended by a small rope atiached to the hanger rod of the lifter and through a pulley to the hand-lever used in connection with the cultivator. The two lifters for the wheels of the sprayer are suspended from an arm attached to the sprayer frame and the hand-lever is used to adjust the lifters and can be operated from the driver's seat. The lifters are made of %" steel rod and the hanger arms from 5/8" steel rod. The lifters for the tractor would be designed as required for each make and model. The accompanying illustration shows the vine lifters attached to the sprayer and the SimpIe-to-Make Potato Vine Lifter Attached
