I"m sure you can mow it in a day. They used to do it with an army large tractor PTO mowers at 30 miles an hour with unskilled drivers. The results were gouged fairways, debarked trees, chewed up fallen limbs, topped off high points, chewed up trash, and very little weed eating.
Now the P&R is on a 3 week schedule, barring rain and 3 days to dry out. They now trim before mowing, use smaller agile tractors with skilled workers, and pick up most of the trash before. Realize the mowers from Swope run all of south KCMO parks, and Swope is the 2nd largest city park in the nation, NY central park is first.
No they aren't perfect, but it is far better than in previous years. Any complaints should go through the course CC. They do not allow the public to mow due to obvious reasons. Doing so unauthorized could potentially close the course.
Enjoy the fact that they do mow the whole course, did recent plantings, were awesome in getting ready for the Worlds and have pride in this plot of land.
Swope, civilized disc golf.
