If you want to achieve the perfect golf course you will need to put a roller behind your mower and plan your route around the grass start buy mowing the headland (all around the edge of the area) to give yourself a cut area to turn around on and then mow in straight lines from one side to the other using the area you have already cut to turn around on. When you have covered the area drive around the headland again to take out any tire marks.
If you cut from North to South one week cut at 45 degrees the next week and another 45 degrees the next time. If you cut in the same direction every time you will very quickly end up with tram lines on the surface.
You will need to aerate the lawn every year as rolling to achieve a quality stripe will cause soil compaction.
Good luck remember practice makes perfect.
