Abstract
A control (100) for positioning and locking the auxiliary transmission section (13) of a compound change gear transmission (11) in neutral is provided. The control includes a selector switch (132) for activating or deactivating the control and a monitoring device (42) for sensing if the main transmission section (12) is in neutral. The control, once activated, will retain the auxiliary transmission section in neutral until the selector switch is switched to a deactivated position (M) simultaneously with the main transmission section shifted to neutral.
