Lawn Mowers - Rotary
Rotary mowers can more easily cope with long, rough grass than other types of lawn mower while also giving a good finish.
up to 250m² 30-35cm (12-14in)
250 - 500m² 35 - 45cm (14-18in)
Over 500m² over 45cm (18in)
Should you leave the lawn longer than you ought between cuts, it won't be such a battle to deal with when cutting with a rotary mower. They are perhaps a better all round solution for most people who use their lawns and want it to look neat and tidy rather than be a show-piece. That is not to say that a fine finish is not achievable with these machines.
It is certainly possible to get the striped finish associated with the best quality lawn with a rotary mower as the stripes are the result of having a rear roller rather than of the blade arrangement. Rotary mowers cut the grass with a centrally mounted spinning blade which while it can give a good finish can't compete with a well adjusted cylinder mower that cuts more cleanly than the chopping action of the rotary.
Small electric rotary mowers may have plastic blades that cuts the grass, this has the advantage that it is far less likely to damage the electrical cable if it is run over than a metal blade. On the other hand such plastic blades are easily damaged by small stones, sticks or other debris, so you should always be sure to have some spare blades to hand in case this happens when you're half way through cutting the lawn.
Some rotary mowers have 4 independent wheels that give high manoeuvrability rather than having two front wheels and a rear roller. If your lawn has lots of beds and/or borders, abrupt corners, or if there are trees planted into the lawn, then a 4-wheeled mower will allow you to more easily cut around them. The mower is unlikely to be powered however so you will need to do the pushing. This style is also very good for long and rough grass when raised to the maximum height, the lack of a rear roller means that the grass is not flattened and so can be more easily cut.
