ABSTRACT:
A loader comprises a pair of lift arms having a bucket pivotally mounted on the forward ends thereof. A tilt linkage, including at least one double-acting cylinder, is operatively connected between the lift arms and the bucket to selectively position the bucket in response to actuation of a control valve operatively connected thereto. A detent mechanism, including a housing movably mounted on the loader, is operatively connected to the control valve for holding it in a rack-back condition of operation. A cable is operatively interconnected between the housing and the cylinder for automatically moving the housing to release the detent mechanism in response to actuation of the cylinder for permitting the control valve to return to a neutral condition of operation.
