How do I smooth out a path here is a gif that shows what I mean, https://gyazo.com/8eddc89e4b69484d22b8974d49c474fd
I want to make a path for the tractor to follow but the paths are just to rough, even if I extrude 10 times or 100 times, it keeps chopping. im a blender noob :/ but if someone knows an easy way for me to make a smooth path that would be great
You can just increase the resolution of the curve:

I also see that you are using a NURBS path with several extrusions to form the simple curved road shape. Curves are designed to help artists interpolate between control points so they don't need to manually add dozens or hundreds of them. Try to use as few control points as possible.
I advise you to use bezier curves, as they offer users much more control over the shape. Here is what the road (I assume it is a quarter circle, I might be wrong) would look like. I added a primitive Bezier Circle and deleted the other 3/4ths of it.
