Mowing is one of the highest recurring costs in professional turfgrass production. For a producer mowing 70 hectares 80 times a year, total mowing costs can easily exceed EUR 75,000 annually.

Yet many operations have never broken down what a single hectare of mowing actually costs, or how much their current system is spending on labour, fuel and tractor time compared to a more efficient alternative.

This article explains the key factors that drive mowing cost and sets out the logic behind the Eco Clipper Mowing Cost Analyser, which you can use below to run the numbers for your own situation.

Mowing cost per hectare consists of five components. Understanding each one helps you interpret what the calculator shows.

Labour is one of the largest single costs in an intensive mowing operation. More hours on the machine mean higher labour costs. An efficiency factor of 1.3 accounts for non-mowing time, such as transport between fields, refuelling and minor maintenance.

Tractor cost covers depreciation, maintenance, insurance and interest on the tractor itself, and is generally higher than the hourly labour rate. A figure of EUR 40 per hour, excluding fuel, is used as the default in the calculator. Because tractor cost is time-based, fewer mowing hours result in lower tractor costs.

Fuel cost depends on two factors: the litres consumed per hectare and the diesel price. Fuel consumption can vary significantly between mowing systems.

Maintenance differs considerably by mower type. Rotary mowers, including Eco Clipper, mainly require blade and bearing replacement at around EUR 0.50 per hectare. Cylinder mowers require regular precision grinding of each reel cylinder and bedknife, as well as bearing replacement, at around EUR 1,000 per reel per year.

Ownership covers depreciation and interest on the mower itself, calculated over a 12-year economic life with a 10% residual value at 5% interest. This is a fixed annual cost, regardless of how many hectares are mown.

In most intensive mowing operations, labour and tractor costs together account for 50 to 70% of the total mowing cost. The mower itself represents a smaller share. This means that any reduction in mowing hours has a disproportionately large effect on total cost.

Mowing capacity, the hectares covered per hour, determines how many hours are needed to cover your daily area, and therefore how much of everything above you spend per year. The formula is straightforward:

Capacity (ha/h) = working width (m) × mowing speed (km/h) × 0.80 ÷ 10

The factor 0.80 represents field efficiency: time lost at headlands, turning and overlapping. The mowing speed in this formula is the straight-line working speed of the machine. This is where the fundamental difference between mowing systems lies.

Cylinder mowers and rotary roller mowers are supported by rollers. Above approximately 10 - 12 km/h, the rollers causes the machine to bounce, creating a washboard pattern in the sward. This is a physical constraint, not a machine deficiency.

Conventional rotary mowers that run on wheels, removing this constraint. Practical working speeds of around 12 km/h are achievable.

Eco Clipper mowers are wheel-supported with an optimised deck design and kinematic suspension, enabling working speeds of 16 up to 20 km/h under standard turfgrass conditions.

The table below shows the mowing hours needed for 70 hectares at different working widths. Eco Clipper hours are highlighted.

The cost components above assume that mowing takes place as planned. In practice, many mowing systems are limited to dry conditions. When mowing windows are missed, grass grows beyond the point where clippings can be left on the surface. Removing the excess is an additional operation with its own labour and equipment cost.

A delayed cut means that more leaf area is removed at once, which sets back root development and slows the growth cycle. The Eco Clipper mowing system operates independently of weather conditions and delivers consistent cutting quality in both wet and dry grass. This keeps mowing on schedule, avoids the need for clipping removal and, for turfgrass producers, supports a faster growth cycle and a denser turf.
