PCT No. PCT/GB81/00069 Sec. 371 Date Dec. 21, 1981 Sec. 102(e) Date Dec. 21, 1981 PCT Filed Apr. 15, 1981 PCT Pub. No. WO81/02966 PCT Pub. Date Oct. 29, 1981.A mower conditioner having a conditioning rotor (22) which is supported at its ends in bearing units (51) that are secured to side support walls (24) by releasable fastening means (56) including a pair of coaxial fasteners defining an axis (68), parallel to that of the rotor axis (23), about which the bearing units (51) and rotor (22) can swing downwards until the rotor (22) contacts the ground, thereby facilitating removal and re-attachment of the conditioning rotor (22). The rotor axis and axis of the fasteners may lie in a plane that is inclined upwards and rearwards from the ground. The rotor (22) may be driven at one end by a spindle (81) that is axially disengageable from the rotor. The spindle (81) may be driven by a chain drive mechanism (71, 76) including an intermediate double ring sprocket (73) that is reversible on its shaft (86) to allow two drive ratios to be selected. |
