Lawn Mower

Lawn Mowers are your last line of defense in your front and back yards. When a zombie gets too close to your house, i.e. past the leftmost column, the Lawn Mower automatically activates and kills all the zombies in the lane, except when in a Pool row in the back yard, as it sinks in the water. At the end of the level, you get $50 for each Lawn Mower left, once zombies start dropping money.

Strategy
There is not much strategy to them, except to conserve your Lawn Mowers but to not waste plants to try and (fruitlessly) prevent your Lawn Mowers from being used up. If it is the last wave, and you have Lawn Mowers in every row with zombies (and/or the Pool Cleaners and Roof Cleaners) you are guaranteed to win the level. However, it is a bad idea to depend on them due to the fact that they give you money.
