PURPOSE: A hay collector is provided to reduce the variation of the center of gravity by making the PTO shaft of a tractor approach the center of a pair of rotary rotors. CONSTITUTION: A hay collector includes a first rotor which is connected to the PTO shaft of a tractor and rotates and a second rotor which is linked with the rotation of the first rotor and rotates. The hay collector includes an input shaft (310) for outputting torque by being connected to the PTO shaft, a connection link (500) which controls a connection angle by being connected to the other side of the input shaft through a first adjustment joint and transfers torque to the first rotor, and an output shaft (600) which controls a connection angle by being connected to the connection link through a second adjustment joint and transfers torque to the first rotor. |
