Putting the biggest mower you can on a property is not always best...in fact, more often than not the SMALLER the better!
Yes, those big zero turns are fun, fast and easy. But they are also very heavy and can cause soil compaction and severe tracking in your lawn if you are unable to change up the mowing patterns. Lawns are also much more succeptible to scalping and tire scuffs with larger mowers.
Obviously if you have a large yard you will need to use a large mower, but if it's border-lined then always lean towards the small mower.
Your lawn will thank you!
