Left-hand and right-hand are referenced from the point of view of the tractor operator.
The flat backside of the belt rides on flat idlers; the inside vee rides in v-idlers and pulleys.

Viewed from below, the PTO clutch pulley is seen at far right (#1). The belt exits the right-hand side of the engine pulley, goes around the right-hand side of the v-idler, around the left-hand side of the flat idler and enters the right-hand side of the transmission pulley.
Viewed from below, the transmission pulley is seen at far left (#2). The belt exits the left-hand side of the transmission pulley and goes directly to the left-hand side of the engine pulley.
A closer view from the right-hand side and below, the v-idler is seen at top (#3).
Viewed from below, looking toward the tranny (#4). The flat backside of the belt rides on the flat idler.
Diagram given on Cub Cadet illustrated parts list (#5). Engine pulley is seen at right; transmission pulley at left.
Viewed from the engine pulley, the upper belt is the primary blade belt (#6). The lower belt is the secondary blade belt.
Viewed from the right-hand side, the secondary blade belt (#7) runs directly from the front of the left-hand blade pulley to the front of the right-hand blade pulley, around the rear of the v-idler and around the front of the flat idler.
