Gear change box comprises a first drive rod (12) having a coupling (K1) for activating a variable speed gear, and a second drive rod (14) for activating a constant transmission (20, 24 and/or 22, 26). Preferred Features: The second drive rod has two constant transmission stages which are formed as starting off transmission stage and an economy transmission stage and can be switched in the second connecting rod via couplings (S1). One drive rod has a switching coupling (S2) by which the variable speed gear or a constant reversing stage can be switched. |
