The bulldozer prop is now fully functional with textures including diffuse and bump maps plus a little bit of specular lighting. Ambient occlusion nodes are present but I did not add rim lights as they don't seem to react well on flat surfaces. I added some manufacturing logos and danger signs to make the prop a bit more than just a "thing".

The prop is also rigged with a simple set of joints and IK handle to mimic robotic movement, it was a bit tricky getting it to work right but given that its only a small prop, complex functionality isn't really necessary. The next task will be to create a small mechanical pincer to pick up rubbish items.
