Lawn Mower

The Lawn Mower is the Player's last line of defense to protect him/her from the zombies. They appears to be much more powerful than instant-kill plants, as it can kill a Gargantuar with only one hit. When the game is finished, each lawn mower will give you a gold coin in Plants vs. Zombies, while a silver coin in Plants vs. Zombies 2.

Pool Cleaner
The pool cleaner is a lawn mower for pool lanes. The can be purchased from Crazy Dave's Twiddydinkies for 1000 coins. Otherwise, regular Lawn Mowers only stop zombies that are out of the pool, as they sink once they fall into the water. Like the lawn mower, it will activate when a zombie approach it.

Roof Cleaner
The roof cleaner is a lawn mower for roof level. Like the pool cleaner, it can be purchased from Crazy Dave's Twiddydinkies, but unlike the pool cleaner, it costs 3000 coins due to the fact there are more roof lanes than pool lanes. When you don't purchase it, the zombies will get past your defenses and climb down the chimney to eat your brains.

Other appearances
The Lawn Mower returned in Plants vs. Zombies Heroes as a Trick card. Its ability is destroying a zombie on a ground lane. Its description is "The thing of Zombie nightmares.".
