gardening machine named rotary cultivator, usually found in home grown vegetable gardens or for soil preparation in traditional gardens. The rotary blades cut in the soil and soften it. Used also to mix manure and fertilizer to soil. The model has been built over an existing tool named 'ursus', and widely used by gardeners and small farmers all over the world. The model is rather accurate in all its parts, and can be used in any agriculture or gardening related render. Materials and textures are easily organized for easy substitution if you need to quickly change chassis color or any other part texture. Model is subdivided in groups (engine, blades, tiller, chassis, handles, etc..), so that any part can be easily removed, resized, detached for any use. Yellow color was chosen as it is the factory color the mchien comes in. Enjoy !
