G'day TC,
I'll look at keeping the Buffalo around the 30mm mark. The verge cops full summer sun and it's not too happy cut shorter. The Zoysia? Probably around 15mm to start with and go from there.
The front roller is something else. Can't wait for it to come back from the blaster. I cleaned it up before I took it in and the deck didn't look as bad. We'll see what eventuates but I'm glad I didn't leave it.
