ABSTRACT:
A shift mechanism for conditioning a transmission assembly of an off-highway implement. The transmission assembly includes a clutch assembly having a manually actuated clutch pedal for facilitating shifting of the transmission from a neutral condition to any of a plurality of drive conditions. The shift mechanism includes a shift lever mounted for movement toward and away from a neutral position corresponding to the neutral condition of the transmission assembly and a shifting assembly connected to the transmission assembly and mounted for movement along a predetermined path of travel. The shifting assembly is moved in response to shifting movements of the shift lever from for conditioning the transmission assembly into any of the plurality of drive conditions depending on the direction of movement of the shift lever. The shift mechanism further includes a neutral lock assembly for preventing movements of the shift mechanism from a neutral position until the clutch pedal is purposefully displaced from a preset position under the influence of the operator.
