Robotic Lawn Mower
You're not being lazy, you're just saving your energy for the things in life that are more important than cutting the grass. A robotic lawn mower does almost all the work for you.
All you need to do is set up a wire around the yard which essentially tells the mower where it should do it's work. The machine you get determines how much lawn it can mow, but some will take care of up to 5 acres.
And robotic lawn mowers are becoming increasingly intelligent. Some will self dock after use or whenever the battery needs to be recharged. Others have rain sensors. So after the initial set up, you may never need to interact with your mower again.
And they are environmentally friendly as well.
