About Large Lawnmowers

If you have a large garden with a lawn between 600 and 1,000 square metres, we would recommend a large lawnmower with a cutting width above 19"/49cm. Large lawnmowers not only have a wide cutting width, but also features that increase productivity and usability to make it easy to maintain your large lawn. Larger mowers also have larger grass collection meaning you can cut more before needing to empty the grass collector.

Wide cutting lawnmowers

The lawnmowers in this section have a cutting width between 49cm and 56cm.

You have the choice between models with petrol engines or cordless (battery) motors with interchangeable batteries, allowing very large areas to be cut by a simple battery change.

A popular feature when you have a large amount of grass to cut is self-propelled drive. As these larger mowers are heavier, many of them feature self-propelled drive which means the mower drives itself forwards and doesn't need to be pushed by the operator.
