You could save a lot of polys by reducing the number of sides on that tube going along the bottom. Right now it looks incredibly wasteful compared to the rest of your geometry.
And maybe it is something about the highlights on them, the normal maps, or the angles (or some combination of all three) but the ?blades? look spherical to me. Distorted spheres, but regardless, not flat circles. I had to look at the wireframe to tell that they were flat.
Also, you're modeling rather inefficiently, and the textures are severely lacking in thought and effort. Those 4 brackets [ along the bottom need only 16 triangles apiece, that tube at the bottom needs only 8 sides 10 at most, and using horizontal cuts (no centerpoint) will save you 2 triangles on every circular shape.
Also, please rotate/mirror those 'blades' because they're super-repetetive right now.
Hm. After a quick google, I think you're making the wrong machine, too.

This machine is used for poultry (chicken)
Looking at the reference that Snader posted, it also looks like the metal detail is scaled too large in the texture.
