ABSTRACT:
A device is provided for tiltably connecting the boom section of a backhoe unit to the dipper section of the backhoe unit. The device includes a first member mountable to the dipper section so as to be rotatable about a first pivot axis transverse to the dipper section. The first member is connectable to the boom cylinder of the backhoe which pivots the first member about the first axis. A second member is provided which is attachable to the boom section of the backhoe. Respective coupling brackets extend from the first and second members to pivotably couple the first and second members and enable them to rotate about a second pivot axis generally orthogonal to the first pivot axis. Fluid cylinder mounting brackets extend from the first and second members adjacent the edges thereof to mount a pair of fluid cylinders in a diagonal crosswise configuration between the first and second members for tilting the first and second members relative to each other about the second axis.
