Abstract
An apparatus for varying the sensitivity of a tractor draft sensing and control system of the type including a draft sensing mechanism having an output link shiftable along its length in response to changes in draft and a draft control linkage having an input arm mounted for swinging movement about a pivot. The input arm is provided with a generally radially extending slot, and the output link is provided with structure slideably received within the slot. A control member, which is adjusted by a screw rod, selectively positions the structure within the slot to vary the moment arm of the input arm which, in turn, varies the sensitivity of the system.
