A novel and practical track-filling apparatus for smoothing rutted soil formed by the repeated passage of wheels. This apparatus includes a frame, a system for attaching the frame to a tractor, and a soil moving blade assembly mounted to the frame. This blade assembly has laterally disposed and spaced apart left and right blades. A system for adjusting the included blade angle between these blades is also provided. This system for adjusting includes a single blade adjusting hydraulic ram that is operatively connected to the blades via a novel yet simple and reliable linkage assembly. Additionally, systems for lifting and tilting the apparatus optimizes operation of this track-filling apparatus over irregular and differing terrain.
