Abstract

A vehicle blade assembly apparatus including a push beam; a blade having a working side and a connection side; an anchoring bracket disposed on the connection side of the blade and having a plurality of mounting bores arranged along an arc around a retention hole; and a pitch link connected to the push beam and to the anchoring bracket using a retention pin configured to be removably placed through co-linear mounting bores on the pitch link and the anchoring bracket.

First claim

What is claimed is:

1. A blade assembly apparatus for a vehicle, said blade assembly apparatus comprising:
a push beam;
a blade having a working side and a connection side;
an anchoring bracket disposed on the connection side of said blade and including a retention hole and plurality of mounting bores, said mounting bores arranged along an arc having a single radius about said retention hole;
a pitch link having a first end and a second end, said first end of said pitch link pivotally connected to said push beam and said second end of said pitch link having a mounting bore; and
a retention pin configured to be removably disposed through one of said anchoring bracket mounting bores and said pitch link mounting bore, thereby selectively attaching said pitch link to said anchoring bracket
wherein the anchoring bracket comprises at least three mounting bores disposed at an equal distance from said retention hole.

2. The blade assembly apparatus of claim 1 , wherein the anchoring bracket includes a pair of parallel extending arm members, and the second end of the pitch link is disposed between the arm members.

3. The blade assembly apparatus of claim 2 , wherein each said arm member includes the plurality of mounting bores, and said retention pin passes through a pair of aligned said mounting bores in each arm member.

4. The blade assembly apparatus of claim 1 , wherein the retention pin comprises a flag pin.

5. The blade assembly apparatus of claim 4 , further comprising a bolt disposed through the flag pin and threadably connected to said anchoring bracket.

6. The blade assembly apparatus of claim 1 , wherein the pitch link has one of a fixed length and a variable length.

7. The blade assembly apparatus of claim 2 , wherein the plurality of mounting bores are oriented generally horizontally.

8. A blade assembly apparatus for a vehicle, said blade assembly apparatus comprising:
a push beam;
a blade having a working side and a connection side;
an anchoring bracket disposed on the connection side of said blade and including a retention hole and plurality of mounting bores, said mounting bores arranged along an arc having a single radius about said retention hole;
a pitch link having a first end and a second end, said first end of said pitch link pivotally connected to said push beam and said second end of said pitch link having a mounting bore; and
a retention pin configured to be removably disposed through one of said anchoring bracket mounting bores and said pitch link mounting bore, thereby selectively attaching said pitch link to said anchoring bracket;
wherein the anchoring bracket comprises three mounting bores disposed at an equal distance about said retention hole.
