Abstract:
A linkage arrangement (10) is provided for moveably connecting an attachment (6) to a work machine (8). The linkage arrangement (10) includes linkage group (12) having an upper arm (14) with a machine pivot point (20) for connecting to the work machine (8) and an attachment pivot point (22) for connecting to the attachment (6). The linkage group (12) further has a lower arm (16) with a machine pivot point (24) for connecting to the work machine (8) and an attachment pivot point (26) for connecting to the attachment (6). An actuator (30) extends between the upper and lower arms (14, 16), whereby during normal operation an increase in the length of the actuator (30) results in the attachment (6) being lowered relative to the work machine (8).
