A grinding arrangement for grinding knives of a chopper drum of a forage harvester includes a movement arrangement for effecting movement of a grinding stone over the length of each of the knives, where individual locations of the knives can be associated with differing grinding times in order that the knives be ground to produce a desired cylindrical profile. A control for the movement arrangement may include either a sensor for determining the need for grinding a given knife at a precise location along the knife and the grinding time required for achieving a desired profile, or predetermined information stored in memory which operates to automatically cause a certain amount of grinding time to elapse in accordance with a specific axial position of the grinding stone.
