Cost

• Manual lawn mowers are usually less expensive than motorized lawn mowers. Another factor to consider is how much maintenance a particular model requires. All lawn mowers will need some maintenance from time to time, but if you have little or no mechanical aptitude, choosing a manual lawn mower may be advantageous.
  
  

Health

• Using a push reel mower is a great form of exercise. Another health benefit to manual lawn mowers is that they are a good choice for people with allergies because they stir up less pollen. Gas lawn mowers can cause health hazards including air pollution and noise, according to ConsumerSearch.com.
  
  

Considerations

• The size of your lawn and how many obstacles it includes are important factors to consider when comparing motorized versus manual lawn mowers. It can be difficult to push a manual mower uphill, so if your yard includes a lot of slopes, you may want a motorized lawn mower.
