NNW Nebraska | Haven't tried it out yet, my cows don't seem to mind going under things, like cedar trees. I built a swinging arm above that trips a micro switch. Only moves one way. Below that, I hung a angle iron on chains. Wrapped it with burlap bags. May even try cedar tree branches, if I have to. I may have to change the settings on my timer so it doesn't trip the valve for something like 1 second. My valve is out about 2 ft from the frame. Playing with a manual switch I found that the cow needs to have her shoulders through the frame before it triggers or she will back out.
Most cows would not go through with a horizontal arm sticking half way through the opening to triger a microswitch..
When they bust a rusty wire under a cedar tree and 200 head will go through that in a short time! | |
