Abstract

A rake frame subassembly includes a front frame segment and a rear frame segment connected by a hinge joint having two or more hinges and an adjustment element. The hinge joint connects or is configured to connect the front frame section and the rear frame section. The hinge joint is also configured to enable both an orientation of the rear frame section relative to the front frame section and a position of the rear frame section relative to the front frame section to be adjusted using the adjustment element, or is configured to enable a position of the rear frame section relative to the front frame section to be adjusted using the adjustment element.

IPC Classes  ?

• A01D 7/04 - Rakes with adjustable rake-bar
• A01D 78/10 - Haymakers with tines moving with respect to the machine with tine-carrying rotary heads or wheels the tines rotating about a substantially vertical axis

Abstract

A torsion spring adjustment assembly for supporting a finger wheel rake that includes a lever operably connected to a torsion spring supporting the finger wheel rake for setting the tension of the torsion spring. The lever is pivotable about the axis of a rotational shaft of the finger wheel rake to a plurality of tension-setting positions and is secured to a main frame of the finger wheel rake at a position selected from the plurality of tension-setting positions. The lever is adjusted to a select position and then secured against the adjustment plate by a mechanical fastener.
