Brake B3 prevents the front planetary gear train's (P2) ring gear from rotating.
The front planet gear runs anticlockwise on the inside of the front planetary gears train's ring gear at the same time as it rotates.
The planet carrier and the driving intermediate gear rotate anticlockwise as a unit at a lower speed than the input shaft.
Since the driving intermediate gear rotates anticlockwise, the driven intermediate gear and the lower planetary gear train's (P3) ring gear rotate clockwise as a unit.
The lower planetary gear train's planet gear rotates clockwise.
Brake B4 prevents the lower planetary gear train's ring gear from rotating.
The lower planetary gear train's planet gear runs clockwise round the sun wheel at the same time as it rotates.
The lower planet carrier and the final gear rotate clockwise as a unit at a lower speed than the driven intermediate gear.
