<p>An angle adjustment mechanism for a bulldozer blade or the like which simplifies the present hydraulic system, while permitting ease of operation. The opposed sides of the blade are connected to slides provided on the side frame members of the bulldozer, a rod-like element or beam having a plurality of spaced apertures is provided on each of the side frame members, at least one of which is slidably supported on the side frame member and a power extender such as a turnbuckle is connected to the slidable beam, permitting adjustment of the beam toward and away from the blade. A latch means such as a conventional latch pin is provided to lock the slides and thereby the blade in the desired position. The blade angle may then be adjusted by (1) releasing the latch means and the slides, (2) adjusting the blade angle, as by engaging an obstacle, (3) adjusting the position of the slidable beam with the power extender, and (3) locking the slides on the beams.</p> |
