What is a Rotary Lawn Mower?
This is the most commonly purchased and used type of mower as they tend to be cheaper than their cylinder counterpart whilst still giving an excellent finish.
Rotary mowers have four wheels and they cut grass horizontally at the pre-selected height using a high speed spinning rotary blade which chops the grass rather than slicing it. The cut grass is then collected at the back of the machine into a designated collection box which you empty later or you can take the box off if you do not wish to collect the clippings.
You can choose from manual push or self-propelled models depending on your needs for example if you have problems with pushing a mower or have large areas to mow than it is worth investing in a self-propelled model which will cost more but will save you hassle, time and energy in the long run.
These versatile lawnmowers are usually electric mains powered although a variety of power sources are available including petrol-driven and cordless rechargeable ones which are ideal for more remote areas or large lawns where power points are not available.
The type you choose will be reflected in the price you pay as a petrol rotary mower (starting from around £200) will be more expensive than an electric one which you could get for around £60 for a smaller model from a Value/Best Buy budget range.
Advantages Rotary Lawn Mower
- Rotary mowers are the most frequently used and inexpensive mower,
- They provide the most even cut because of the mechanical arrangement of the mower; the four wheels are located on the corners of the machine and so are within the perimeter of the widest swing of the blade. This means that the front wheels flatten the grass which is then vacuumed in to the blades path so that it is all cut accurately to the same level.
- Also, because the blade cuts past the wheel path, the mower is able to cut and neaten up close to any fences, flowerbeds and edging without having to use a trimmer,
- You can attach a grass collection box which collects any debris, small twigs and leaves that come into the mowers path like a vacuum,
- They can cope with dipped, sloped and uneven lawns,
- The rotary mowers technique is suitable for cutting longer grass and weeds to a uniform height – although the power of the mower can affect its effectiveness/ability and
- They create a respectable, tidy finish which is best for typically sized family lawns which are used regularly.
Disadvantages Rotary Lawn Mower
- Due to the nature of the rotary blade, although it cuts grass quite short and parallel to the ground, the finish is not polished and perfect and so it is not suitable if you are hoping to have a flawless finish,
- Also, the presence of four wheels may serve as a bit of a hindrance if you have irregular lawn borders.
- The motor in a rotary mower vibrates and so can be quite noisy. Those which are powered by gasoline can be costly because they require gasoline and oil and they release carbon dioxide and other toxins into the air. Furthermore, they require a yearly oil change which needs disposing of correctly. Electricity and battery powered do not have this fuel requirement but have their own shortcomings; with an electric mower you have to drag the power cord around after you, ensure that it is long enough or switch power supply’s half way through and always stay conscious that you do not mow over and cut the cord whereas mower batteries degrade with use/time requiring costly replacements and then battery disposal issues,
- The engine in a powered mower only works the blade so it can be quite physically exerting pushing the weight of the mower and the motor (and the grass collector) especially if you have a hill,
- If you choose not to use a cutting collecting attachment, the mower can discharge pebbles, twigs and other debris as well as spreading dust in drier weather conditions. In wet weather, the cut grass tends to land in clumps which need to be raked up and collected and
- Rotary mower wheels are generally smaller than those on a reel mower and so the mower may jolt on uneven land. You can however get rotary mowers with bigger back wheels which can help reduce this problem.
