How much grass can your mower cut? The most basic way of calculating this is to take the width of the mower and multiply it by the speed. Let's say our mower is 2 meters wide and can mow at 10 km/h (keeping the math simple here). In one hour it will have cut 20,000 square meters or 2 ha. Wow, that's a lot of grass. Unfortunately it's not that simple. A lot of things go into how much grass you can cut and any observant turf manager will know that the actual productivity of a mower will be much lower than the maximum theoretical productivity as calculated above. This post will discuss what influences mower productivity and strategies we can use to maximize how much grass we can cut with a given mower or resource input. So why isn't our actual mower productivity the same as the maximum theoretical productivity? A lot of "mowing" isn't actually mowing. We use an hour meter to calculate how many hours the mower is operational and during this operational period
