Rear folding boom center frame can be repositioned on the lift arm attaching angles to increase/decrease operating height as needed.
On rear fold boom the frame can be attached at any one of seven different height positions.
Operating height can also be changed by moving lift arm attaching hardware to various positions on the attaching angles.
Due to design of the center frame the top two holes (A) cannot be used for lift arm attachment.

Install 5/8 x 2-3/4 in. cap screws, spacers, lock washers and nuts in both left-hand and right-hand frame members, where lift arms attach. Be sure to use corresponding holes in frame members so frame is level when attached to lift arms.
Attach lift arm and straps at holes (B), when lowest operating height position (D) is desired.
Attach lift arm and straps at holes (C), for highest operating height position (E).
