Pollution

• Zero-turn lawn mowers are powered by gasoline, which gives off air pollution. Because these lawn mowers are more powerful than other mowers, they give off more pollution. While newer models have a catalytic converter that limits the amount of pollution compared to older models, the pollution is still significant when compared to other types of mowers.
  
  

Cost

• Zero-turn mowers often cost significantly more money than push mowers and riding mowers. The average cost of a standard riding mower is $1,600 to $3,000, while zero-turn lawn mowers cost an average of $2,600 to $7,200. While commercial operators may benefit from the many advantages a zero-turn lawn mower offers, residential operators may not be able to justify the higher price for a machine that may only be used a few times per month.
  
  

Performance

• While zero-turn lawn mowers are able to mow large properties, they are unable to mow hills. Individuals who have anything more than gentle slope on their property will not be able to use a zero-turn lawn mower effectively. Slopes shouldn't be any more than 15 degrees.
  
  

Safety

• Cutting decks on zero-turn mowers are located on the front of the mower along with an engine, and may cause the mower to tip over or fail to make it up a slope. When mowing on wet terrain, operators may lose control of the mower, which may lead to damage to the machine or property. It's important to mow the lawn while the grass is dry.
