Backup alarm activation mechanism for power shift tractors

摘要

An apparatus for signalling an intended reverse operation of a mechanism having a shift lever selectively positionable in forward, neutral, and reverse positions prior to placement of the shift lever in the reverse position for effecting reverse operation. The apparatus includes an activating structure responsive to movement of the shift lever in the neutral position toward the reverse position for activating the control of a signalling device prior to reverse operation of the mechanism. The apparatus is adapted for use in signalling the back-up operation of a vehicle, such as a tractor, before the tractor starts in a reverse direction motion.
