The Yoke is the upside-down "Y" shaped piece, with a 1" steel shaft.  The Yoke Barrel (sold separately) is placed over the Yoke's shaft, which allows the picker section to articulate with grease fittings.  The Yoke fits on both the Innovator® and Innovator® Plus pickers.

We also supply a Heavy Duty Yoke, which is designed for Innovator® Plus Pickers, and for the front section of Innovator® Pickers used with very rough terrain.  The Heavy Duty Yoke includes an extra contact point to strengthen the connection of the 1" shaft to the upside-down "U" portion.
