Frequently asked questions

Divide the lawn area by your mowing rate. A 500 m² lawn at 300 m² per hour takes about 100 minutes.

A push mower covers roughly 200–400 m² per hour; ride-on mowers are much faster. Adjust for your equipment.

Obstacles, slopes, turning, trimming and emptying clippings all add time beyond the open-area estimate.

Use a wider deck, mow in long straight passes, and keep the blade sharp so you can move at a steady pace.
