A tractor linkage control has a draft load measuring device in the form of an elongated bar extending between two spaced supports on the tractor, the draft links are connected to the bar to cause the same to deflect under draft loads, measuring means are provided to measure the maximum angular deflection of the bar to provide a usable control signal over a large range of draft forces. The measuring means includes an elongated member clamped at one end to the bar at its point of maximum deflection and having its free end operable to move a cam member carried on the bar. |
