Buying guide for Sun Joe Lawn Mowers

You can already tell that Sun Joe has a wide catalog of lawn mowers that deliver in performance. However, simply buying one without any careful considerations can be costly or will not give you the right cutting power for your needs. Here are some of the factors to consider when choosing a lawn mower.

Lawn size
The first and important factor to always consider is the size of the outdoor space you plan on using the lawn mower on. Powerful mowers with long-lasting batteries are great for maintaining lawns that are an acre of the yard or more. However, these mowers can be too much for front yards that take only 10 minutes to cover. On the other hand, mid range lawn mowers can take a long time to cut two miles worth of grass since you need to keep recharging the battery.

It pays to match the cutting performance of a lawn mower to the size of your outdoor space. A good indicator is the battery capacity and motor wattage. Higher capacity and watts are suitable for large spaces while the low battery and motor power are best for small areas. Another option is to opt for wired mowers that give you unlimited running time so you can cover any area without interruption.

Cutting height options
The second factor to consider is the cutting height setting of a lawnmower. This may seem like less important criteria to think about since you are cutting the grass to a reasonable size. However, the length of the grass can create a specific look on your lawn. Cutting the grass to the lowest height possible will give you a smooth clean yard. However, giving the grass some height will result in a lush outdoor area that seems comfortable to your feet.

Clippings discard options
Nearly every lawn mowers let you capture all clippings and other foliage with a nylon bag. On the other hand, other machines have a mulch option that cuts the grass into a fine particle. These particles decompose on the soil and enrich the soil. Mulching is great at developing the grass on your lawn.

Final Conclusion

These nine Sun Joe mowers make it easy to mow your lawn. Always keep in mind the different factors on picking a lawn mower to find the right unit.

Corded units might be a hassle to use. However, they provide an affordable and uninterruptible means to maintain outdoor spaces regardless of their size.
