One neighbors yard that I mow to help them (because they are super busy at work farming 15,000 acres) has a side hill that no matter how you make a 180 degree turn, it's going to be uneven because of the shifting of the machine and also the rider leaning into the hill and not even realizing it. I just mow over the crown of the side hill before making the 3 point turn around and problem solved.......
Even though the neighbors property line is on the side hill, I talked to their neighbor and he agreed that if I mow over the hill a few feet onto his lawn, it prevents him from having to make the opposite turn on the hill facing down or mowing the hill from side to side. Essentially, he feel the less he has to mow, the better..........Works for everyone.
If the hill has a sharp crown, I will lift the deck right as i reach the top of the hill to avoid any scalping and then drop the deck back to mowing height as I pass the crown of the hill. Mowing up and down inclines always provides a better looking cut, not to mention is much safer that side hill mowing.
Also, unexpected dips and holes in the lawn which cause a wheel to drop will cause the uneven cutting and it is often noticeable when looking across the lawn (not to mention the jarring on your spine when you hit the hole). If you suddenly develop a dip or hole in your lawn about the size of a lawn tractor tire and it's not due to animal activity, it can mean you have a leak in your underground irrigation piping, which washes out the subsoil because of the pressure of the leak. I have seen this numerous times over the years when the poly pipe either fails or the sprinkler head housing ruptures underground. So if you have a new "BUMP" in your lawn which you didn't have before, consider the option of a water leak from irrigation or drain piping as a possible source.
It's not how fast you mow, it's how well you mow when going the proper speed.........
