Types of Lawn Mowers – Rotory Type
There are two main mower types : Reel Type Lawn Mowers and Rotary Type Lawn Mowers. There are many. Making the right choice for the best lawn mower can ensure that your beautiful lawn is kept green, healthy and really, without a doubt make your lawn care and maintenance much easier in the long run. Usually, what can help determine what type of lawn mower that you will use, is the TYPE OF GRASS and what lawn mower will cut it most efficiently. Then you may need to move your thoughts over to the comparison on features and costs.
Rotary Type Lawn Mowers
Gasoline
Most rotary push mowers are powered by internal combustion engines. Such engines can be either two-stroke or four-stroke cycle engines, running on gasoline (petrol) or other liquid fuels. Internal combustion engines used with lawn mowers normally have only one cylinder. Power generally ranges from two to seven horsepower (1.5 to 6.75 kW). The engines are usually carbureted and require a manual pull crank to start them, although electric start is a sales feature in some countries. In the past, rotary mowers had a manually-controlled throttle to increase or decrease engine speed.
Newer models usually have a pre-set throttle speed that prevents over-revving and improves engine life. Gasoline mowers have the advantages over electric mowers of greater power and distance; however, they have several disadvantages: more noise; required cleaning of the spark plug for soot from a dirty air filter (dust/clippings);[2][3] storage and transport of fuel; and two-stroke gasoline mowers require a specific fuel/oil mixture.
Electric
Electric mowers are further subdivided into corded and cordless electric models. Both are relatively quiet, typically producing less than 75 decibels, while a gasoline lawn mower can be as noisy as 95 decibels or more.
Corded electric
Corded electric mowers are limited in range by their trailing power cord, which may limit their use with lawns extending outward more than 100-150 feet from the nearest available power outlet. There is the additional hazard with these machines of accidentally mowing over the power cable, which stops the mower and may put users at risk of receiving a dangerous electric shock. Installing a residual-current device (GFCI) on the outlet may reduce the shock risk. On the United States market as of summer 2008, a corded electric mower from a respectable manufacturer costs about the same as an entry-level internal-combustion mower ($150–200), with significantly higher reliability, significantly lower cost of ownership, and a significantly reduced carbon footprint.[5]
Cordless electric
Cordless electric mowers are powered by a variable number (typically 1-4) of 12 volt rechargeable batteries. Typically more batteries mean more run time and/or power. Batteries can be in the interior of the lawn mower or on the outside. If on the outside the drained batteries can be replaced with recharged batteries. Cordless mowers have the maneuverability of a gasoline powered mower and the environmental friendliness of a corded electric but are more expensive and come in fewer models (particularly self-propelling) than either.
