ABSTRACT:
A haying machine has a plurality of rotary rakes spaced apart transverse to its travel direction. Each rake has a plurality of tines extending through a housing rotatable about an upright axis and each having an inner end secured in a ball rotatable about an element nonrotatable in the housing but axially displaceable therein. The times each have an upper section about which they may be twisted by cam action, and a lower section that normally extends at a right angle to the ground. When the element in which the balls are carried is lifted all the way up control arms on the rake elements ride a cam to orient these elements with respect to the ground with the orbits of adjacent rakes spaced from each other, and when this bearing plate is lowered the control arms are moved out of contact with the cams in the housing and the rake elements are lifted so as to define an orbit of larger diameter that overlaps with the orbit of the neighboring rake.
