A push-pull coupling for tandem earthmoving scrapers is disclosed wherein the coupling may be rapidly connected or disconnected, thereby permitting the scrapers to operate either in unison or separately. A push block having a pulling hook projecting therefrom is mounted on the rear of a forward scraper, while a push block and a bail for engaging the hook are mounted on the front of a rearward scraper. Furthermore, at least two sets of two-way shock absorber assemblies which can absorb the shock loads caused in the course of the pushing or pulling operations are respectively connected between the push block of the rearward scraper and a reinforcing member fixedly secured to the front thereof.
