This paper presents a spatial dataset describing the three-dimensional (3D) morphology of furrows generated by a rigid runner traversing granular materials under systematically controlled loading conditions. The dataset comprises 375 experiments conducted according to a full factorial experimental design involving three granular materials—silica sand (0.3–1.0 mm), silica sand (1.4–2.0 mm), and river silica stone (2–6 mm)—two tool geometries, three traversing speeds (0.017, 0.034, and 0.051 m s −1 ), and five normal loads, with five repetitions for each experimental configuration. The dataset contains 3D surface scans and reconstructed surface models acquired after each tool pass. These data enable detailed characterization of furrow geometry, including groove width, depth, displaced material dimensions, tool penetration profile, and cross-sectional slope angles. By systematically varying grain size, tool geometry, traversing speed, and applied load, the dataset provides a comprehensive benchmark for investigating soil/tool interaction mechanisms and quantifying experimental variability. The dataset is intended to support the validation and calibration of terrain mechanics models, discrete element method (DEM) simulations, and other numerical approaches used in off-road mobility, geotechnical engineering, bulk material handling, agricultural engineering, and waste management.
