ABSTRACT:
A forage harvester having an automatic grinding mechanism for the knives of the cutterhead, the grinding mechanism comprising a carriage carrying grinding means and being reciprocated back and forth across the cutterhead in the griding mode by endless drive means. The carriage is coupled to the endless drive means by a coupling member which is attached to the endless drive means chain and pivotally attached to the carriage. The coupling member is shaped and dimensioned such that the pivot axis of the connection to the carriage is substantially coaxial with the axis of rotation of each of the two sprockets which define the extent of the two runs of the endless drive means when the connection of the coupling member to the chain passes around that sprocket in moving from one run of the chain to the other. The drive means is provided with control means having means for commanding the termination of the grinding mode, and carriage-position-sensing means operable to deenergize the drive means at the end of the grinding mode such as to dispose the carriage in substantially the same home position at the end of each grinding mode irrespective of the position of the carriage at the instant of commanding termination of the grinding mode.
