摘要： A forage harvester having an automatic grinding mechanism (14) for the knives (10) of the cutterhead (9), the grinding mechanism comprising a carriage (17) carrying grinding means (15) and being reciprocated back and forth across the cutterhead in the grinding mode by endless drive means (33-42). The carriage (17) is coupled to the endless drive means (41) by a coupling member (44) which is attached to the endless drive means chain and pivotally attached to the carriage, the coupling member being 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 guide means (40,42) which define the extent of the two runs of the endless drived means (41) 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 (33-42) is provided with control means (46, 48, 56-64) having means (64) for commending the termination of the grinding mode, and carriage - position - sensing means (48) operable to denergise the drive means (33-42) at the end of the grinding mode such as to dispose the carriage (17) in substantially the same "home" position at the end of each grinding mode irrespective of the position of the carriage at the instant of commending termination of the grinding mode.

摘要： A forage harvester has a metal detector with permanent magnets (18-20, 21-23) located within a crop feed roll (10), additional permanent magnets (30, 32) being positioned beyond the ends of the feed roll and at a distance greater than the radius of the feed roll from the axis of rotation of the feed roll. The additional magnets (30, 32) cooperate with magnets (18, 23) within the feed roll (10) to provide a more uniform flux density across the width of the feed roll, even in regions near ferrous side sheets (26, 28) defining the lateral limits of the harvester feed path. Tramp metal is thus detected with equal facility regardless of its trajectory past the feed roll (10).

摘要： A bale size sensor such as a potentiometer (66) is driven by one of the serpentine arm assemblies (42) used to maintain apron tension during formation of a round bale so that the output of the potentiometer (66) continuously provides an indication of the size of a bale being formed in the baler. A microprocessor (100) based control circuit senses the output of the potentiometer (66), converts it to a digital value, and compares the digital value with a value representing a desired bale size. When the two values are equal, the microprocessor (100) computes the number of revolutions of a feed roll (23) of wrapping material that is required to wrap the bale a preselected number of times, energises the feed roll mechanism to feed wrapping material into the bale forming chamber (20), and counts the revolutions of the net feed roll. When the required amount of wrapping material has been dispensed, the microprocessor (100) stops the feed roll (23) and activates a mechanism to cut the wrapping material. The size of a "full bale" is selected by actuating keys on a control panel. An offset is automatically provided to compensate for wear in the apron mechanism (14) affecting the "zero" setting of the bale size sensor (66). The system permits signalling the operator to steer left or right along a windrow to control bale shape as the bale being formed in the chamber increases in diameter, the signalling rate being non-linear with respect to bale diameter.
