Benny, turn grass brown all the time. This how ever is in writing, we do our best job not to brown grass.

If the customer wants to have us suspend the hose over the lawn we use somthing similar to a saw horse and suspend the hose all the way to hard surface.

reducing the heat is soemthing I never messed with because i know it will increase the time.( time is money)

Brown grass in AZ comes back quickly, however we do have Scottsdale resorts if we damaged the lawns they would send me a bill for the turf replacement and it would be changed the next day.

Good luck, I have photos of the hose horses, maybe i can post them.
