ABSTRACT:
A rake machine has one or more circular rake members that is rotatable about an upwardly extending axis. Each rake member has an outer rim to which depending sleeves are attached and a shaft is turnably received in each sleeve. The lower end of each shaft is pivoted to a time support and each support has an outer end with a pair of times pivotally connected thereto. The supports each have thin inner ends located within the rim and a counter-weight is secured to each inner end. The supports are shaped so that upon rotation, the tines pivot outwardly, or generally radially, with respect to the member's axis of rotation whereupon the center of gravity of each support is shifted so that the supports pivot about the rim to position the tines further outwardly. A setting disc around the member's axis of rotation can be fixed in several positions to change the working positions of the tines and each shaft is interconnected to the disc via an arm that has a pin which fit in one of the slots around the periphery of the disc so that turning the disc turns the support and its tines.
