A strapping machine configured to feed a strapping material around a load, position, tension and seal the strapping material around the load, includes a work surface table height adjusting assembly. Such a strapping machine has a machine frame, a work surface for supporting a load mounted to the frame a strap chute for carrying the strap around the load, a feed assembly for feeding and retracting strap and a weld head for sealing the strap to itself. The machine frame is mounted to leg assemblies by first and second height adjustment assemblies. Each height adjustment assembly is configured to raise and lower a portion of the work surface relative to a fixed portion of the leg assemblies. The assemblies each include a pair of adjusting rods lying along a respective side of the frame, at adjacent comers of the work surface. The adjusting rods operably connect the work surface and the leg assemblies. Each adjusting rod is secured to its respective leg assembly by a support to restrain longitudinal movement of the rod and to provide rotational freedom relative to the leg assemblies and the frame. Each adjusting rod is engaged with an engaging member longitudinally movable along the adjusting rod that is mounted to the frame such that rotation of the adjusting rod raises or lowers the work surface relative to the leg assembly.
