Being a qualified greenkeeper, I may be of some use here..

. These answers are similar to how we used to look after the greens and tees on the course, just tweaked for a home lawn situation where it doesn't need quite as much attention.
1. How often do you mow? Every week in summer, sometimes twice a week. About every 3 weeks or so in winter
2. At what height do you mow? Summer height, I'm guessing about 9 or 10 mm (haven't measured it yet), winter a few mm more say about 14-15mm. I leave it longer in winter to retain moisture, and also to try to prevent weeds as much as possible, although it doesn't always work. It depends on what sort of grass you have too, those heights are for Qld Blue couch.
3. Do you fertilise? If so with what and how often? Spring and Autumn, at the moment I'm using Munns Golf Course Green. I also scarify and aerate before fertilising.
4. Do you water? If so how often and what type? IE sprinkler, soaker hose. Not with the current water restrictions. It's been raining enough anyway.
5. Have you top dressed you lawn? If so what materials did you use? I haven't yet but I've been thinking about it, I'd most likely use a sandy loam, which would go on after fertilising.
6. What sort of weed control do you use? MCPA/Dicamba. More commonly known as broadleaf weed killer.
7. What sort of mower do you use? SB Model 33 16" cylinder mower.
At the course obviously we'd mow more frequently, and also spray for disease and pests regularly, monitor the soil and water it to a program, but I don't think that's really necessary in a home lawn situation.
