A stiff rod connects two arras, one on each furrow-wheel spindle, causing themto track by steering the rear in unison with the front wheel as the horses direct the latter bythe swing of the tongue. Deeres Gilpin Sulky-Plow has a self-lifting device, introduced in 1881. The settmg ota lever causes the draft by the team to run the plow out of the ground. The same lever con-trols depth of work and levels the run of the plow by means of the arched frame with doubleeccentric crank axles, so that when one wheel is raised the other is lowered, and the plow anddrivers seat can be kept always level.
