A corner arm sensor is provided for sensing the angle of the extension boom with respect to the main boom. A plurality of first sprinklers are positioned on the extension boom along the length thereof and a plurality of second sprinklers are positioned on the extension boom along the length thereof. The water which is normally allocated to the end gun on the outer end of the extension boom is supplied to the second sprinkler during certain periods of time that the end gun is not activated.
