Consider the overall cost you would pay for a riding mower vs a robotic lawnmower. Even a pushmower isn't a wise choice for some owners: If you cut grass for 2 hours a week for 25 weeks with a 5.5 HP gas powered lawnmower, you're spending $56.00 for gas ($3.00 per gallon), about $70 for yard waste pick up service and $300.00 - $600.00 for a lawnmower (initial cost), that you still have to push! And riding mowers cost even more, making the choice for robotic lawnmower even easier.

Before deciding to go with a traditional mower, do a little research on robotic lawnmowers. They are reliable, mulch the grass finer than regular mowers, fully automatic, self charges and mows on a schedule. Plus it's quiet enough to mow at night without disturbing anyone. Cost-wise they are a good choice because they are very low maintenance... only require new blades once a year. No gas! No Tune-ups!
