Mower having a continuously variable power split device

A grass mower, said mower comprising:

• a power generator;
• a blade reel;
• a drive drum;
• and
• a power split device comprising:
• a single power input shaft operably connectable to the power generator;
• a reel output shaft operably connected at a distal end to the blade reel;
• a drum output shaft operably connected at a distal end to the drive drum;
• at least one continuously variable transmission (CVT) hub operably connecting at least one of a proximal end of the reel output shaft and a proximal end of the drum output shaft to the power input shaft such that torque and rotational speed delivered by the power input shaft is transferrable to the at least one of the reel and drum output shafts at any infinitely variable ratio;
• and
• a reel clutch mechanism structured and operable to engage and disengage the delivery of power from the power input shaft to the reel output shaft.
• wherein, the power split device is structured and operable to transfer the torque and rotational speed delivered by the power input shaft to both the reel and drum output shafts such that a rotational speed of the blade reel and a rotational speed of the drive drum are both generated from the power delivered by the power input shaft and are both independently controlled.
