A vehicle transmission system has a gear-type transmission with a plurality of gears and a plurality of claw clutches which transmits a torque between an input shaft of said gear-type transmission and an output shaft of said gear-type transmission. In addition, a soil aeration apparatus may operate without a centrally disposed support shaft, thus enabling the tine-holder shafts to be positioned closer to one another and reducing the size of the apparatus. In order to guarantee a firing position, the projectile magazine and the propellant charge magazine, may be moved relative to the weapon barrel.
