A machine for smoothing ground surfaces without undue compaction, comprising: a chassis; smoothing means consisting of two rollers, both of said rollers being of cylindrical form and at least about eight inches in diameter; mounting means for mounting said rollers in laterally spaced positions on said chassis, substantially symmetric with respect to an axis of symmetry centrally located on said chassis and extending parallel to the longitudinal axes of said rollers, said rollers being mounted for rotation about their longitudinal axes in generally horizontal, normal orientations, and for pivotal articulation about normally vertical axes, said mounting means also enabling oscillation of one of said rollers about a normally horizontal axis generally perpendicular to said longitudinal and vertical axes thereof; a driver\s seat so mounted on top of said chassis as to afford a seated driver a substantially unobstructed view along the entire length of both of said rollers; drive means on said chassis, comprising an hydrostatic system, operatively connected for effecting simultaneously driven rotation of both of said rollers, at selectively variable speeds, said hydrostatic system including a reservoir for hydraulic fluid mounted on top of said chassis; and steering means on said chassis operatively connected for effecting simultaneous pivoting of both of said rollers in opposite directions about said vertical axes, said driver\s seat, steering wheel, and reservoir being disposed substantially on said axis of symmetry for optimal weight distribution and driver\s visibility.
