The old impacts we are replacing have lasted well over the years but over time the nozzles,shafts and springs wear and the performance becomes uneven and unreliable.
Fairways Pop Ups on 1-6 now all have modern gear driven heads on them which are more reliable and give a better more even coverage .Over the next couple of weeks we will be replacing old heads on another 4 fairways ,improving the performance of the system when we do need to irrigate : )
