Main groups A01F 5/00-A01F 12/00 and A01F 17/00-A01F 21/00 provide for threshing devices and for accessories that are directly connected with threshing. Combines, and details of combines that are not directly connected with the threshing action (e.g. mowing, feeding or vehicular features) are covered by A01D.

Baling

Main groups A01F 13/00-A01F 21/00 are application-oriented places for methods or apparatus for baling that are specially adapted for straw, hay or like harvested products of plant origin. Baling of compressible fibrous material in general is provided for in B65B 27/12. Baling presses in general is provided for in B30B 9/30. Bales of material are provided for in B65D 71/00.

Bundling

Main group A01F 1/00 is an application-oriented place for stationary apparatus or hand tools for bundling, which are specially adapted for straw, hay or like harvested products of plant origin. Binding of harvested products by mobile apparatus in the field is provided for in A01D, for example in A01D 37/00, A01D 39/00 and A01D 59/00. Bundling of compressible fibrous material in general is provided for in B65B 27/12. Bundling of articles in general is provided for in B65B 13/00.

Cutting

Main groups A01F 3/00 and A01F 29/00 are application-oriented places for apparatus or methods that are specially adapted for cutting up or disintegrating straw, hay or like already harvested products of plant origin. Mowing and other cutting down of standing plants is covered by A01D and A01G. Cutting in general is covered by B26. Disintegrating in general, e.g. by rotating knives, is covered by B02C.

Storing

Main group A01F 25/00 is an application-oriented place for mechanical aspects (e.g. material handling aspects) of apparatus or methods that are specially adapted for storing harvested agricultural or horticultural crops. Containers for storage of articles or materials in general is covered by B65D. Storing and associated handling of bulk material or articles in general is covered by B65G. Civil-engineering aspects of silos or similar bulk storage containers are covered by section E, for example E04H 7/00.
