Like the Osoto-gari (Large outer reap), this Osoto-guruma (Large outer wheel) reaps both of the opponent's legs, throwing onto his back.
In order to facilitate a forward pull, Tori (Player executing technique) Tsurite (Lifting hand) grasps Uke (Player receiving opponent’s attack) collarbone area, and his Hiki-te (Pulling hand) grasps Uke below the elbow.
Tori pulls Uke forward on the Hiki-te (Pulling hand) side, and moves his body inward and advances his Support leg to Uke Tsurite (Lifting hand) side.
At the same time, Tori bends the knee of his Tsurite (Lifting hand) side leg to prepare for wrapping it around behind Uke.
When Uke is then destabilized toward the back, Tori extends his prepared leg behind Uke (beneath his hips) and uses that leg as a fulcrum to throw Uke in a rotational motion onto his back.
The throw is performed most efficiently with Tori Tsurite (Lifting hand) grasping Uke collar, with the inner side of his elbow lifting Uke jaw to force him back, and with his Hiki-te (Pulling hand) pulling Uke.
Because this Waza reaps both legs from behind, it is important to keep using the Hiki-te (Pulling hand) effectively even during the throw to prevent the opponent's head from striking the floor with too much force.
