Flip block assembly for changing dozer blade pitch

摘要

The invention is an in a dozer blade pitch adjustment assembly of the type having a blade pivot pin spaced from a reference line on a dozer blade assembly. The improvement comprises a flip block eccentrically mounted between lugs of the blade assembly for pivoting movement between a first position and a second position. Flipping the block to the first position or to the second position changes the spacing between the pivot pin and the reference line and the pitch of the blade is thereby changed. The block is retained in one position or the other by bolts extending through the lugs and into the block.
