A work vehicle includes a torque converter having a lock up clutch and a controller that conditionally allows operation of the lock up clutch in a locked position or an unlocked position. The controller determines a plurality of active work vehicle parameters during operation of the work vehicle and includes a plurality of ready to dig parameters. The controller determines a ready to dig condition or a non-digging condition of the work vehicle by comparing at least two of the active work vehicle parameters to at least two corresponding ready to dig parameters. The controller disallows operation of the lock up clutch in the locked position in response to the ready to dig condition, allows operation of the lock up clutch in locked or unlocked positions in response to a non-digging condition. Operation of the lock up clutch avoids the engine from stalling in a ready to dig condition.
