I've used those, tractor blowers, and my mechanics shop fan with a generator (wouldn't recommend stealing mechanics shop fan

. I have precision fans on every green, but sometimes I will need a little extra on some far sides. I would run it as wide open as your members can deal with from a noise level. Just make sure it is blowing across the green and not down on it or it will wilt the area in front of the blower. It is not going to make it through the night on a tank of gas unless your mechanic can rig up a larger external tank.
