However some people having heard how hard it is actually find it far easier than expected. Once your pattern is perfected the hard part is over. When buying consider your needs. Do you want fully automated hands off mowing? You are then best suited for a fully automated unit with a docking station. Consider the size and slope of your lawn when choosing a model. If you have slopes more than 15 degrees a LawnBott is likely a better choice than a RoboMower. If you have a very large yard LawnBotts have models designed for the largest spaces. Alternatively you can consider buying 2 smaller units to work in tandem.
Secondly for self-propelled mowers power will be sent to the rear wheels to drive the mower forward thus negating any need for the operator to push. But remember the more the engine has to do the powerful it needs to be. There will usually be a throttle on the handlebar that regulates the amount of fuel being fed into the carburettor at any one time. The greater the pull on the throttle the more fuel the engine receives which increase the revolutions per minute (RPM). As the RPM increases so does the power output of the engine.As already mentioned above the rotating blade under the mower then captures the grass underneath either by suction or by a cylinder blade "grabbing" the grass and then the blade cuts at the desired height.
These mowers are equipped with gears that engage the front wheels. This means that in many cases all you have to do is steer the mower rather than having to push the mower. This feature can come in handy especially if the lawn you are mowing is a large one or has an undulating surface. On top of all of that these self-propelled mowers help to speed up the lawn mowing process and considering that these mowers are a bit more expensive than a standard push mower this may be all the convincing a person will need to purchase one of these mowers. Mowing the lawn does not have to be such an ordeal. Just because you do not have a riding mower does not mean that mowing the lawn cant be easy. Push Lawn Mowers are a good way to cut grass. For a small lawn it will likely be all you will ever need and you will not have to spend a fortune on one. A self-propelled mower while being a little more expensive is still not a huge expenditure and for medium to larger sized lawns makes the job of cutting the grass a lot easier.
The combustion within the engine then powers the cutting blades of the mower which can either be rotary or cylindrical. The rotary blade acts like the big hand on a horizontal clock. They rotate clockwise cutting the grass as they turn. In most case there are 4 blades and they are shaped to produce an updraft of air as they spin like an aircraft propeller. This causes a differential in pressure under the mower which pulls at the grass before cutting it. The rotating blade mower works much like youll see on a combined harvester. One blade will capture and lift the grass and then the next blade in the cylinder will cut it.
