摘要： An impeller conditioner for an agricultural mowing machine includes a rotor, an attachment device located on the rotor, a tine device pivotally attached to the rotor between a first end and a second end of the tine device via the attachment device, and a positioning device located on one of the rotor and the attachment device. The positioning device include a tapered portion which restricts the tine device in a first position to have less lateral movement than the tine device in a second position. The first position can be an operational position and the second position can be a non-operational position.
