A 01 DHARVESTING; MOWING


Notes

(1)This subclass covers the shredding or pulverising of stubble, e.g. for the purpose of producing mulch, but does not cover other mechanical destruction of unwanted vegetation, which is covered by group A01M 21/02. [7]

(2)In this subclass, in groups A01D 34/00, A01D 42/00, A01D 43/00, A01D 57/00, A01D 67/00, A01D 69/00 and A01D 75/00, it is desirable to add the indexing codes of groups A01D 101:00 or A01D 103:00. The indexing codes should be unlinked. [7]

(3)In this subclass, in groups A01D 42/00 to A01D 45/00, it is desirable to add the indexing codes of group A01D 151:00. The indexing codes should be unlinked. [7]
