Motor grader with detachable link for reduced blade angle operation

In a motor grader which comprises:

• a power unit having a main grader frame extending forwardly therefrom, said frame being supported adjacent its forwardmost end by ground engaging means;
• a circle drawbar mounted below said frame intermediate said power unit and said ground engaging means;
• a circle member mounted below said circle drawbar;
• gear means for rotating said circle member relative to said circle drawbar;
• a blade mounted to said circle member and therebelow;
• first hydraulic cylinder means rotatably mounted at a first end thereof adjacent said frame and at a second end thereof adjacent a periphery of said circle drawbar;
• said first cylinder means including a rod which is retractible therein, said first cylinder means with said rod fully retracted therein defining a minimum total length;
• second hydraulic cylinder means rotatably mounted adjacent a first end thereof adjacent the periphery of said circle drawbar and adjacent a second end thereof adjacent said frame;
• and an improvement which includes
• means for permitting operation of said motor grader at a reduced angle of said blade to a surface being graded, including a detachable link connected in line with said first cylinder means to extend the length thereof, said link having a length such that when said link is connected to said first cylinder means in line therewith and said first cylinder means is at said minimum total length thereof, said first cylinder means and said link are of a collective length which prevents rotation of said blade beneath said frame from a first of said motor grader to a second side thereof, said first cylinder means, when said link is removed therefrom and said first cylinder means is at said minimum total length, allowing said blade to be rotated beneath said frame from said first side to said second side.
