I have heard one explanation that it is like "cranking a lawn mower".

. . . it may be helpful to understand this.

Properly understood, this is a great analogy for the On Plane Right Forearm Takeaway.

Unfortunately, most 'lawn mower crankers' I see -- even professionals demonstrating -- fail to 'fan' the Right Elbow (as is required for Power). Thus, in this misconception, the Hands remain between the Right Elbow and the Ball, and the Elbow moves straight back along the line the Right Forearm is positioned.

This is Push Basic Stroke (10-3-C), and for full shots demanding Power, trust me . . .

One Plane or Two . . .

That ain't the way it works.
