The blade assembly (20') may include a first elongated blade (122) and a second elongated blade (124), where the first elongated blade (122) and the second elongated blade (124) each include a trimming portion (126) and a high-capacity trimming portion (128). The trimming portion (126) of each of the first elongated blade (122) and the second elongated blade (124) may include a set of trimming teeth (130). The high-capacity trimming portion (128) of each of the first elongated blade (122) and the second elongated blade (124) may include one or more high-capacity trimming teeth (146) that are longer than the trimming teeth (130), The high-capacity trimming portion (128) of the first elongated blade ( 122) or the second elongated blade (124) may further include a first guide tooth (142), the first guide tooth (142) being disposed on a first side (180) of the one or more high-capacity trimming teeth (146) of the first elongated blade ( 122) or the second elongated blade ( 124). The high-capacity trimming portion ( 128) of the first elongated blade ( 122) or the second elongated blade ( 124) may further include a second guide tooth (144), the second guide tooth (144) being disposed on a second side (182) of the one or more high-capacity trimming teeth (146) of the first elongated blade (122) or the second elongated blade (124). The first guide tooth (142) and the second guide tooth (144) may be longer than the one or more high-capacity trimming teeth (146) of the first elongated blade (122) or second elongated blade (124).La présente invention concerne un ensemble de lame (20') qui peut comprendre une première lame allongée (122) et une deuxième lame allongée (124), la première lame allongée (122) et la deuxième lame allongée (124) comprenant chacune une partie de taille (126) et une partie de taille à haute capacité (128).
