I would agree Micro Rain has a better reel gun than Kifco.
I will say there are better ways to irrigate than with a reel gun. My
experience is you are loosing 50 to 65 percent of your water to
evaporation depending on temperature, humidity and wind.
If you are going to irrigate every year I would suggest underground
irrigation. Your efficiency will go way up. It will require less
water, less pressure, less horsepower,less money and less manpower.
Pumps will cost less and electricity costs will down and instead of
moving the reel gun you will just flip a switch or just put it on a
timer.
I have worked on thousands of acres of Pecans Orchards in Texas I
have seen what works and what does not.
I would bury pipe and keep emitters near the tree, anything above
ground is a target for squirrels, rats, mice or any other varmits,
farm equipment and stupid employees.
Most of the initial cost of this type of irrigation are labor and
markup. It is very labor intensive to install, BUT after the install
it is the least labor intensive. You can water the whole orchard at
one time instead of waiting for the reel gun to get there. Or zone it
depending on how much water you want to lay down at a time.
Just a suggestion from a Water Well Man.
