An earthmoving attachment to be mounted on the front end of a tractor. The attachment includes a frame secured to the tractor, arms pivoted to the frame and extending forwardly and mounting a combination bucket and blade. Hydraulic cylinders individually extend telescoping sections in the arms to effect a skewing of the blade. Another hydraulic cylinder mounting a slider adjacent one end of the blade is operable to tilt the blade or bucket. Other sets of hydraulic cylinders tip the bucket and lift the arms conventionally. Simple adjustments are operable to convert the attachment from the configuration of a front-end-loader to that of a dozer, and to skew, tilt and tip the blade and bucket in various configurations.
