Enhanced ability to preserve the conditions of golf course by reducing course wear and tear turf damage from driving carts and dragging hoses on turf.
Less interruption / inconvenience for golfers.
More professional look for golf course; do not have to drag hoses from green or leave hoses on sides of fairways and greens.
Irrigation system can be pressurized to act as a blower for leaves and other debris on greens; this will save time and allow for a much more effective mowing process (system must be hooked-up to a compressor and the water blown out).
Maximizes labor efficiency by making the job easier and less burdensome to greenskeepers (takes out the monotony of the job).
Hand watering vs. sprinkler watering will give a more even and or isolated watering distribution to the green; more effective and higher quality application will preserve and protect the green from bad exposures.
Provides the resources to react timely in urgent situations such as extreme heat stress, dry conditions, and possible hydraulic oil leaks. Cost of units for eighteen holes is a small fraction compared to the overall costs of a full irrigation system.
