When the mower is pushed along the ground, the wheels rotate and some of this energy is transferred through the gears to power the cutting blade.
The absence of a motor on these lawn mowers makes them almost silent.
They produce no air pollution.
They are cheap to operate since they require minimal maintenance and no fuel.
Operating these lawn mowers can be exhausting due to the fact that all energy being used to propel the blades has to come from you.
As a result of the strenuous activity involved in operating such mowers, they are unsuitable for mowing extensive lawns.
Factor #2 – Operation
Lawn mowers can be operated using several techniques. Most commercial mowers are guided by hand.
Other versions include ride-on mowers which are driven around like cars, and robotic mowers.
Hand-Drive Lawn Mowers
Hand-driven lawn mowers are the most common. The person using it simply pushes the mower over the area that needs trimming. Such lawn mowers are the most suitable for small home lawns and gardens.
They are the cheapest mowers to buy.
They are easy to operate.
They cannot be used practically in large lawns or areas such as golf-courses.
Ride-On Lawn Mowers
Ride-on mowers have a seat for the person operating them. They are larger than hand-driven lawn mowers and are controlled using a steering wheel just like in motor vehicles.
Such lawn mowers are mostly used on large lawns such as golf courses and public parks.
They cover large distances in little time and also require less physical effort making them suitable for extensive projects.
Due to their size, they are impractical for use in most home lawns.
They are very expensive to purchase.
They have high maintenance costs.
Robotic Lawn Mowers
These are sophisticated electric lawn mowers that are designed to work on their own. To use one, you will only need to define the boundaries of your lawn using a specially designed wire which transmits low-frequency signals to the mower to guide its position.
Using this wire as a boundary guide, the robotic lawnmower moves automatically to trim grass within the set boundaries.
Such lawn mowers also have an added guidance feature that enables hem to change their course when they encounter an obstacle such as a rock or post around the lawn.
They require no physical input.
Their operation is silent.
They are highly priced.
They can sometimes miss some areas within the lawn since they rarely move along straight lines.
Factor #3 – Blade Type
The type of blade fitted on a lawn mower is the most crucial factor that determines the quality of cutting.
There are two blade types used in lawnmowers; rotary blades and cylinder blades (also referred to as reel). Using either of these blades will produce significantly different results.
Rotary Lawn Mowers
Rotary lawnmowers have a single blade attached to a vertical shaft. These blades spin at a very high speed and cut the grass through a shredding action. Rotary mowers are the most suitable for longer grass ranging between 2 to 4 inches in length.
Rotary mowers are able to cut through thick, long grass with ease.
Rotary mowers produce coarse results due to their shredding action of cutting, especially when the blades are poorly maintained. This can sometimes lead to the yellowing of freshly-cut grass along the shredded edges.
The rapidly-spinning blades found on rotary mowers are extremely dangerous and can easily cause serious injuries when handled incorrectly.
These mowers are also extremely noisy.
Cylinder/Reel Lawn Mowers
Cylinder mowers have several curved blades attached onto a horizontal axle. These blades push grass onto a sharp cutting bar which then cuts the grass like a pair of scissors.
The effectiveness of cylinder mowers can be further enhanced by increasing the number of blades.
Cylinder mowers produce a clean even cut making which makes them the most preferred lawn mowers for exotic luxury lawns such as golf-courses.
They are less noisy than rotary mowers.
Since they have less mechanical elements in their design, they are easy to maintain and are less prone to breakdowns.
Cylinder mowers are only suitable for mowing short grass (less than 2 inches long).
They produce inconsistent results when used on uneven terrain.
Before using a cylinder mower on your lawn, you will have to pick up all obstacles such as stones and twigs. Unlike a rotary mower which is powerful enough to cut through any loose object on the ground, the blades on a cylinder mower will jam whenever they run into an obstacle.
Factor #4 – Accessories
Lawn mowers nowadays come with a wide range of accessories meant to increase safety, improve the appearance of the freshly-cut lawn and to make your work easier.
Most accessories are available as aftermarket parts. The list below includes some of the useful lawn mower accessories that you may want to consider going for.
These are compartments that trap bits of cut grass being thrown back by the blades as the mower moves on the ground and conveniently stores the waste for easy disposal.
Most modern lawn mowers come readily equipped with a grass catcher. If your mower lacks one then you can purchase it as an aftermarket accessory.
These are rollers that can be attached to the rear end of a lawn mower to produce linear strips along the cut lawn similar to the ones visible on sports arenas.
The sharpness of a lawn mower blade has to be regularly maintained to ensure consistent results. Sharpening kits come with abrasive sharpening tools and instruction manuals that guide you on how you need to sharpen the blade without damaging it.
