Feed Trough Construction
We bought an 18 wheeler load of used oil pipeline out of Oklahoma. Each pipe was 26 inch diameter, 45 feet long, and weighed 100# per linear foot.
We built concrete feeding pads 10 feet wide and 100 feet long. The pads were formed up with 2X4 lumber. We now use 2X6 forms for the last 10 feet at the ends of the pads to prevent them from breaking off from the weight of the tractor.
The ends broke off due to the heavy tractor and feed wagon. This was remedied by pouring the ends 6 inches thick and using 4000 psi concrete. Also, the grade around the concrete should be built up with gravel to be higher than the concrete.
The concrete pads are spaced 2 1/2 feet apart. This leave a nice slot in which to set the feed troughs.
The trough ends are left open so they won't hold rainwater. This also allows us to overlap the ends in order to make feed bunks as long as we need them for a particular situation
