摘要：
A shock-absorbing tongue assembly for coupling a rotary cutter with a work vehicle includes a coupler configured to couple to the work vehicle, and a linkage mechanism having a proximal end at the rotary cutter and a distal end at the coupler. The linkage mechanism includes a suspension element configured to dampen energy transferred between the rotary cutter and the work vehicle, a primary linkage mechanism extending from the rotary cutter, and a secondary linkage mechanism extending between the primary linkage mechanism and the coupler. The secondary linkage mechanism is configured to rotate about the primary linkage mechanism while maintaining the coupler in a level condition.
