AbstractA manually operable creep control mechanism for a tractor of the like having multiple direct drive gears and a creep clutch. The mechanism comprises an elongated arm pivotally mounted on the control box cover plate adjacent the slot through which the gear shift lever travels to shift into the direct drive gear positions. In a first position, the arm is clear of the slot and the gear shift lever is free to move through the entire range of gear positions, while preventing inadvertent pivoting of the arm out of the first position once the lever is in a predetermined low gear, such a fourth. When pivoted to a second position, the arm lies across the slot and limits shifting of the lever to a predetermined higher gear, such as twelfth, while preventing inadvertent movement of the arm out of the second position once the lever is at or beyond the fourth gear position. A flexible switching cable is connected to the arm and an electrical switch for actuating the creep clutch. When the arm is in the first position, the switch is off and when the arm is in the second position the switch is on.
