A pair of connector assemblies (118 and 120) are connected to the frame (26). A plurality of parallel straight tines (36) are connected to the base member (28). A right shaft (42) and a left shaft (54) are pivotally attached to the frame (26) for pivotal movement about parallel axies that are perpendicular to the axies of the straight tines (36). Arcuate tines (74 and 78) are attached to the right and left shafts (42 and 54) and are pivoted into and out of engagement with bales by a hydraulic cylinder (82).

  • Patent number: 5507530
    Abstract: Male fluid couplers (14) are attached to a control valve (94) mounted in a holder (96). Female fluid couplers (16) have their sleeve members (72) held in an aperture (108) in a sleeve member retainer (110) by snap rings (112). Lever arms (122 and 124) are attached to the sleeve member retainer (110) by pins (126 and 128). Pins (134 and 135) on the lever arms enter slots (136) in the male holder (96). Movement of the lever arms (122 and 124) moves the female couplers (16) into engagement with the male fluid couplers and allows locking balls (40) to move into locking ball grooves (38). Upon release of the handle (130), the spring (80) moves the sleeve member (72) in a position locking balls (40) in the grooves (38). Movement of the handle (130) in the opposite direction moves the sleeve members (72) into position to release the balls (40) from the grooves (38). Continued movement of the handle (130) moves the female couplers (16) from engagement with the male couplers (14).
