Different types of lawn mowers to suit every need, if you do not see it here ask for it my mail.
Some mowers are walk behind types the needs to be pushed while other are self propelled. In the self propelled range you have those that you walk behind and other you ride on. While the walk behind push type mowers mow at a speed of 5km/h self propelled mowers have set speeds and some have gear settings to manage the mowing speed. To calculate how many square meters could be mowed in an hour you simply take the cutting width and multiply it with the cutting speed. Remember that it depends on the type of lawn, how many obstacles like trees you need to cut around, managing the electrical cable if any, refueling, fatigue etc.
