Abstract
The disclosure is of, in a mower which works over a great cutter width and comprises cutter discs or cutter drums or cutter belt pulleys or other rotary elements involved in the cutting operation, at least one device for reducing the width of the windrows comprising an endless flexible windrowing member which travels around two drums having substantially vertical axes of rotation, the first of said drums being approximately above one of said rotary elements at one extremity of the mower, the second of said drums being spaced to the rear of and nearer to the middle of the mower so that the windrowing member follows a path at an acute angle to the cutting front, at least one of said drums being driven at a speed different from that of said rotary elements so that the windrowing member impels cut fodder from a margin towards the middle of the windrow.
