It can be confusing when trying to decide which lawn mower is best for your lawn, since this depends on several things such as your grass variety, lawn contours and region. There are gas and electric lawn mowers that range from small and inexpensive to large and pricey. It is important to understand what needs you and your lawn have before picking out the best mower to purchase.
Examine your lawn's contours and grass variety. Is your grass constantly wet from shaded spots? Are there lots of small hills or tree or planter corners to turn around? Does your grass have thick or thin blades? Keep these things in mind when shopping for a mower. For example, if you have a lawn that slopes, a self-propelled mower is a good choice so you don't have to rely on manually pushing it. If you have a lot of edges or obstacles to cut around (such as bushes, trees, planters, gardens, etc.) you want a mower with good maneuverability.
Figure out your price range. Mowers can range from under $100 to several thousand, depending on the brand and what you're looking for. Keep your budget in mind, along with the characteristics you need your mower to have when you go to the hardware or garden store to look at mowers.
Decide if you want a reel, rotary or electric mower. Reel mowers can cut lawns shorter because of their shearing action and are commonly used on golf courses. Rotary mowers are rising in popularity now because leaving the grass clippings on the lawn is part of the "green" and "natural composting" movement. Electric mowers are a step up from rotary mowers with the added bonus of being easier to use and better for the environment than the gas-powered ones. You can even consider riding mowers if you have a large enough lawn and a budget of over $1,000.
Consider efficiency and maintenance of the mower. Some need extensive cleaning after each use, while others need minimal time. This all depends on how much time you spend on landscaping. Some mowers also offer amenities such as bagging and mulching, while others only offer the basic feature of cutting grass. If you want to save yourself time, consider going with a lawn mower that combines several tasks at once.
