1. A transmission for a drive train in an agricultural or heavy load vehicle, the transmission comprising:
a central drive shaft;
a first planetary gearset including
a first sun gear non-rotatably coupled to the central drive shaft,
a first planet gear enmeshed with the first sun gear, and
a first planet carrier rotatably engaged with the first planet gear;
a second planetary gearset including
a second sun gear non-rotatably coupled to the first planet carrier, and
a second planet gear enmeshed with the second sun gear;
an output drive element including a ring gear enmeshed with the second planet gear; and
a brake device; located operatively between the first planet carrier and the output drive element, such that the output drive element is selectively fixedly couplable to the first planet carrier via the brake device,
wherein the output drive element is selectively rotatable based on engagement of the output drive element with the first planet carrier via the brake device.
