The gated pipe system can move water through the field with a small amount of effort on the part of the farmer. Just open the gate! 

Blade and Linkin like to help ‘set water’ when we are watering the gated pipe fields.  Of course, they have a bit of trouble understanding just how ‘wide’ to open the gates, but they are catching on.  Open the gates two fingers wide of Grandpa’s, or four fingers wide of theirs.
