A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.
Lithium-ion batteries are common in home electronics. They are one of the most popular types of rechargeable batteries for portable electronics.

Keeping your yard in pristine condition nowadays needs some serious consideration. Hiring someone else to do it for you would be pretty expensive considering the economic condition nowadays so it is better to look for cheap lawn mowers and do it yourself, right? Absolutely, since it is something that you need to do periodically so that the façade of your home is always presentable to your neighbors and passersby and to ensure that your backyard remains a clean and quiet retreat for you and your family.

However, if keeping the front lawn and the backyard trimmed were the only consideration it would be very easy but you need to consider how you do the mowing because of current environmental issues. Luckily, there is an approach to the situation that can be considered a healthy alternative while a providing a solution to the environmental issue! It all begins with finding the right mower from among all the collection of cheap lawn mowers that would help you do the job and at the same time give you a light warm-up!

Cutting the grass in your front lawn and backyard with old-fashioned but modern lawn mowers gives you a win-win solution. Old-fashioned because it has no gasoline powered motor that will add to your carbon footprint and modern because it is constructed from lightweight but high tensile strength metal and industrial plastic and more efficient in cutting grass! Today’s cheap lawn mowers does not really reflect cheap because cheap here translates more into affordable rather than second-rate.

In case you haven’t noticed, these push-pull lawn mowers are making a big comeback. They are absolutely green, environmentally friendly AND they will definitely keep you fit! Mowing the front lawn for 20 minutes each weekend is a good enough warm-up before you hit the jogging path for a 2-mile jog! Of course, if you have a big lawn then a push-pull mower may not be ideal but maybe if you schedule your lawn mowing activities, then maybe it would just work out!

Push-pull mowers have several valid reasons going for them, at the top of the list is that they are cheap lawn mowers, they’re green (zero smoke and zero noise pollution) and they are economical to maintain, just a squirt of lubricant here and there!

Among the long list of cheap mowers, here are three models that come highly recommended by customers who bought and are using them to take care of their lawns. Incidentally, one of them is battery powered, pushing the cheap lawn mowers category one notch higher.

There’s the Gilmour RM30 20-Inch Reel Mower that comes fully equipped with a grass catcher. The unit has a 20-inch mowing width and has an extra wide dual shrub/blade guard to guarantee operator’s safety. Sporting a dual wheel design for greater stability, the mower’s adjustable knife bed allows easy cut height adjustment from 1 to 3 inches. Other features of the mower are the ergonomic design of the handle for a comfortable grip and shelf-sharpening reels.

The Scotts 2000-20 is another 20-Inch classic push reel mower on the list of cheap lawn mowers. Features of the Scotts 2000 include 10-inch dual tracking wheels, adjustable cutting heights, composite wheels and a 2-year warranty.

The America APT1216 GoMow belongs to a new species of cheap lawn mowers. The GoMow is powered by a 24-Volt rechargeable lead-acid battery and has a 16-Inch mowing width. The unit has a 50-minute operating time per charge, more than enough for homes with small lawns and comes equipped with a grass catcher.

Using reel lawn mowers will certainly make your lawn look good especially if your lawn is no bigger than 1000 square feet. Aside from being able to keep your lawn trimmed and presentable, you will also gain that lean physique and sweat off excess pounds just mowing your lawn.
