specifically the irrigation systems are basically a long pipe on wheels that’s fed from and pivots around the center of the circle exactly like the minute hand on a clock face.
This allows for very few moving parts and energy to keep the circle watered. You can hit those corners but the equipment is much more complicated so more difficult and costly to run.
