| 摘要 |
A tractor blade assembly is disclosed having a first blade member and one or more replaceable, supplemental blade members. The first blade member has a supplemental blade mounting section extending laterally beyond the side edge of the first blade member and a supplemental blade member that removably attaches to the supplemental blade mounting section such that a side edge of the supplemental blade member abuts the side edge of the first blade member. The tractor blade assembly may include alignment structure to restrict vertical movement of the supplemental blade member relative to the first blade member and align the side edges. |
