Abstract

An in-line gearshift mechanism for use with a powershift transmission of an agricultural vehicle. The gearshift mechanism includes a shift lever assembly, a shifter plate and a switch plate each separated by a plurality of spacers and secured as an integral unit to a frame portion of an interior of the agricultural vehicle. The shifter plate includes a plurality of in-line detent positions defining forward upshift, forward, forward downshift, neutral, reverse downshift, reverse and reverse upshift detent positions at which the shift lever may be positioned. The shift lever includes a gear encoder plate on which a plurality of switch activating elements are positioned.
As the shift lever is moved between the above-mentioned detent positions, the switch activating elements selectively actuate selected ones of a plurality of reed switches disposed on the switch plate. The reed switches generate signals indicative of the position of the shift lever, which may then be used to inform an external controller of the position of the shift lever and thus the desired operation (i.e., forward upshift, shift to neutral, etc.). In the preferred embodiment a neutral detection limit switch is also included which is actuated when the shift lever assembly is placed in the neutral position. The preferred embodiment also includes a throttle lever for adjusting the speed of an engine of the agricultural vehicle. A program further determines if forward downshifts or reverse downshifts are in fact desired by the operator as the shift lever assembly is moved through the forward downshift and reverse downshift positions.
