Lawn Mower

Lawn Mowers (lawn mowers in Plants vs. Zombies 2) are the player's last line of defense in their front yard and backyard. When a zombie gets too close to their 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 backyard, where it kills only zombies that have gotten out of the pool, then sinks into the pool. At the end of the level, the player gets $50 in Plants vs. Zombies and $10 in Plants vs. Zombies 2 for each lawn mower left, once zombies start dropping money in Level 2-1. This can kill Gargantuar and Giga-gargantuar, despite it being only one instant kill, making it one of the strongest weapons in the game (only losing to Giant Wall-nut, which can even defeat Dr. Zomboss), along with Pool Cleaners and Roof Cleaners.

The sound when a Lawn Mower moves down a lane.

Plants vs. Zombies
There is not much strategy to them, except to conserve your lawn mowers. However, do 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 may win the level. However, it is a bad idea to depend on them, as they give you money, along with the Pool Cleaners and Roof Cleaners. Using a Garlic effectively, you can move them towards lanes with Lawnmowers or away from rows if your missing one.

Plants vs. Zombies Adventures
Like its predecessor, Lawn Mowers are used as a last defense. However, Lawn Mowers do not follow the path zombies can take, but rather a straight path from where it is activated, and may not end up killing every zombie in a lane. Additionally, if the player plays a level they have already passed, lawn mowers will not be present, but the player must use the Lawn Mower boost to regain them. Any knocked-out plant along an activated lawn mower's route will be revived instantly if it has recovered completely. There is also an achievement for playing and finishing a level without using any lawn mowers, called Lawn No-er.

Plants vs. Zombies 2
The use of lawn mowers is similar to the use in Plants vs. Zombies. In version 2.1, you can manually launch lawn mowers if you have unlocked the Mower Launch upgrade. This can be very helpful if you have a Sweet Potato to lure the enemies to one lane (or you can put two in the second and fourth lanes ahead, and one near the back in the third lane, to take out everything). Mower Launch is also effective in Piñata Party if your being overwhelmed and need to target a zombie in the back that is protected or a Imp Cannon holding a vital Plant Food. One thing to note is that do NOT use lawn mowers for last resort for every type of zombie, as when Weasel Hoarders, and Chicken Wrangler Zombies, get run over, they still release their animals, making it a risk, especially when you have reached high levels in Big Bad Butte and Icebound Battleground.

Specific to Plants vs. Zombies

 * Lawn Mowers are even more powerful than instant kill plants, as they can kill even a Giga-gargantuar in one hit.
 * However, Giant Wall-nut is more powerful as it can kill Dr. Zomboss in one hit.
 * If the player types "trickedout" while playing, their Lawn Mowers change and have a monster truck-like appearance, but its wheels do not get bigger.
 * The Lawn Mower has three achievements related to it: Close Shave, Last Mown Standing, and Lawn Mower Man.
 * When a Lawn Mower is activated on a Pool row, it will sink and leave a trail of smoke which will disappear very quickly.
 * When a Lawn Mower meets a zombie, it will slow down. This also happens with Pool Cleaners and Roof Cleaners.
 * When a Lawn Mower kills a zombie, the zombie will only be left with their heads.
 * The only land zombies that will die in a different way instead of being squashed are the Zomboni, the Catapult Zombie, the Zombie Bobsled Team (in their bobsleds), the Gargantuar, and the Giga-gargantuar.
 * In most modes, when a Lawn Mower has been activated, the zombies will not enter that lane for a while. It is probably either because the other zombies are scared by the Lawn Mower and stopped attacking for a while, or to give the player enough time to recover his/her plant defenses from that lane. Also, if all Lawn Mowers, Pool Cleaners, or Roof Cleaners are used shortly before the final wave except for one, the final wave is only in a single row and can be defeated with a Jalapeno.
 * In the online version of Plants vs. Zombies, zombies will turn into a puff of smoke once it meets a Lawn Mower.
 * Not all zombies have their mowed animation as being squashed; some turn into puffs of smoke, some get sucked (although this rarely happens), and some will disappear (on water if the player has not bought the Pool Cleaner).
 * In the mini-game Heavy Weapon on the Xbox, PS3, and PS Vita version, you will need to control a Lawn Mower with a plant on it in order to shoot zombies.
 * For some reason, the Lawn Mower doesn't hurt plants.
 * Also, real Lawn Mowers cut down grass, but in this game, it does not.
 * In Portal Combat, if the Lawn Mower gets into a portal, it will go to the portal in the different lane.
 * The Lawn Mower in game is a reference to the Peter Jackson movie Braindead, where the protagonist Lionel Cosgrove uses a lawnmower to fight zombies in the climax. The Lawn Mower in game looks almost identical to the lawn mover in the movie.

Pirate Seas

 * Lawn mowers are the only lawn mowers that cannot go fully across the lanes, due to the water in the middle. They do go all the way across if the lane has planks over the water.
 * The lawn mower's blade has been replaced by a brush. It is probably because it is more like a polishing machine for the ship's deck.
