"Environmental" criteria

Positif Effect on air quality: Increasing


acidification: DECREASE


GHG emissions: DECREASE


Positif Effect on fossil resource consumption: Decreasing


fossil energy consumption: DECREASE


Neutre Other: No effect (neutral)


Pollutant transfer to water (N, P, pesticides ...): no effect (neutral)


Pollutant transfer to air (N, P, pesticides ...): Decrease


Using the test bench allows diagnosing malfunctions leading to overconsumption. Carrying out the recommended adjustments and repairs reduces fuel consumption and related sulfur dioxide emissions.


Fossil energy consumption: Decrease


Using the test bench allows diagnosing malfunctions leading to overconsumption. Carrying out the recommended adjustments and repairs reduces fuel consumption: 50% of diagnosed tractors have at least one anomaly causing an average overconsumption of 1.5 liters per hour. For a tractor used 600 hours per year, the potential fuel saving is therefore 900 liters per year.


GHG emissions: Decrease


Using the test bench allows diagnosing malfunctions leading to overconsumption. Carrying out the recommended adjustments and repairs reduces fuel consumption and related greenhouse gas emissions: 50% of diagnosed tractors have at least one anomaly. For a tractor used 600 hours per year, the emission of 3.5 tons of carbon dioxide per year on average can be avoided.

"Agronomic" criteria

Neutre Productivity: No effect (neutral)


Neutre Soil fertility: No effect (neutral)


Neutre Water stress: No effect (neutral)


Neutre Functional Biodiversity: No effect (neutral)

"Economic" criteria

Neutre Operating costs: No effect (neutral)


Positif Mechanization costs: Decreasing


Using the test bench represents a cost of about €100, plus any necessary adjustments and repairs. However, this diagnosis allows reducing fuel consumption by 1.5 liters per hour on average, i.e., a saving of about €500-600 per year for a tractor operating 600 hours annually.


Positif Margin: Increasing


Using the test bench allows increasing profitability by reducing mechanization costs.

"Social" criteria

Neutre Working time: No effect (neutral)


The time to perform the test bench is about 1 hour.


Neutre Observation time: No effect (neutral)
