ABSTRACT:
A side-shift backhoe includes a slide frame having an upper end forming a downwardly opening receptacle having a cylindrically curved inner surface engaged with a complementary shaped surface of an upper transverse guide rail of a support frame. The slide frame also includes a transverse member which is releasably secured to a lower end of the frame and includes an upwardly- and rearwardly-facing abutment surface disposed for engagement with a downwardly and forwardly-facing abutment surface of a lower transverse guide rail of the support frame. A pair of linear hydraulic swing actuators are located between upper and lower transversely-extending mounting bars, and the cylinders of the actuators are each swivelly mounted to the bars with the bars and actuators forming a swing actuator unit. The swing actuator unit is releasably secured to the slide frame such that the actuators project through a central, fore-and-aft extending opening provided in the slide frame.
