Abstract
A mower implement includes a cutter bar extending along a central bar axis. A rotating blade assembly is mounted on the cutter bar. The rotating blade assembly includes a disc rotatable about a disc rotation axis relative to the cutter bar, and at least one blade pivotably mounted to the disc. A blade sensor is mounted on the cutter bar. The blade sensor has a sensing field, and is positioned to detect movement of the at least one blade of the rotating blade assembly through the sensing field during each rotation of the disc about the disc rotation axis. A diagnostic controller receives the data signal from the blade sensor and is configured to analysis the blade signal and identify a fault in the rotating blade assembly. The diagnostic controller may then notify an operator of the identified fault.
