Abstract
A dozer blade pitch adjustment apparatus has a mounting lug and a block supported by the lug for setting a dozer blade at a first pitch or a second pitch. In the improvement, the lug has a mounting surface and the block has a first face contacting such mounting surface when the blade is set at the first pitch. A second face of the block contacts the mounting surface when the blade is set at the second pitch. The block has a surface portion between the lugs and such portion faces generally upwardly when the blade is set at either pitch. A new method for changing the pitch of the blade is also disclosed.

In a dozer blade pitch adjustment apparatus having a mounting lug and a block supported by the lug for setting a dozer blade at a first pitch and, alternatively, a second pitch, the improvement wherein:
- the lug has a mounting surface;
- the block has a first face contacting the mounting surface when the blade is set at the first pitch and has a second face contacting the mounting surface when the blade is set at the second pitch.
In a pitch adjustment apparatus mounted on a dozer blade and having (a) a pair of mounting lugs extending from the blade, and (b) a block supported by the lugs for setting the dozer blade at a first pitch and, alternatively, a second pitch, the improvement wherein:
- the block has a surface portion between the lugs;
- and
- the surface portion faces generally upwardly when the blade is set at either pitch.
In a dozer blade assembly having (a) a dozer blade, (b) a pair of mounting lugs, and (c) a pitch block attached to the mounting lugs, a method for changing the pitch of the blade including the steps of:
- removing the pitch block from the mounting lugs;
- rotating the pitch block about 180.degree.;
- and
- re-attaching the pitch block to the mounting lugs.
