ABSTRACT:
A rake machine has two rake wheels that are driven to rotate about upwardly extending axes. Each member has a rim and groups of tines are pivoted to the rim. The tines can be pivoted from lower, crop working positions to raised, inoperative positions. A respective tine engaging device on a holder can be set to intersect the tines during rotation thereof and displace same upwardly against spring bias. A latch engages each of the inoperatively positioned tine groups until centrifugal force overcomes the resistance and the tines pivot outwardly and downwardly into operative positions. The devices of the rake wheels are linked to a lever which can displace the devices to protective positions for the tines. The rake wheels are displaceably mounted along the length of a transverse beam and the beam is linked to a coupling trestle by a parallelogram linkage that can be set to reposition the rake members. The parallelogram linkage is connectable in an offset position with respect to the center of the trestle and a driving connection is supported by a bearing located to one side of the parallelogram linkage.
