* Default prices are based on national averages as of 12/2/2024. Don't forget that tax-exempt non-road diesel can be used in your clean diesel mower. Multiply retail diesel by 0.88 for the average price of non-road diesel.
** Weekly propane prices are only collected by the U.S. Energy Information Administration during the heating season (October through March). Visit www.eia.gov for more information.
2. Fuel Expense Per Year
Here are the calculations for commercial zero-turn mower(s).
(Professional pump/motor drive system; fuel-efficient horizontal shaft engine; 24-inch drive tires; commercial fabricated deck)
Based on approximately equal engine displacement & horsepower (800 - 850 cc; 25 - 27 hp)

3. Emissions Reduction - The "Green" Factor
When calculating the impact of mowing equipment on the environment, it is critical to account for emissions per hour of mowing, not simply gallon-to-gallonLitre-to-Litre comparisons. Per-hour totals based on mower(s).
| Carbon Dioxide* CO2 |
Hydrocarbons + Nitrous Oxides HC+NOx |

4. Increased Productivity - Increased Revenue
With greater power in tough mowing conditions (more than 50% more power than propane), Grasshopper MaxTorque™ Clean Diesel mowers allow you to complete jobs up to 50% faster. Faster job completion allows you to accept additional jobs, increasing billable hours -- resulting in increased revenue.
Based on your hourly billing rate of: $ and hours per mower.
| With MaxTorque™ Clean Diesel Power: | Additional Billable Hours (potential) |
Additional Revenue (potential) |
| Increase billable hours, versus gasoline (per year) | ||
| Increase billable hours, versus gasoline (over 3 years) | ||
| Increase billable hours, versus propane (per year) | ||
| Increase billable hours, versus propane (over 3 years) |
Even if billable hours are not a concern, municipalities, school districts, universities and large-acreage homeowners can save man hours of labor by using more powerful, fast-mowing MaxTorque™ Diesel Mowers.
5. Trade-In Value
Trade-in values per mower based on blue book and dealer-supplied data and 3,000 hours of use (average 3 years of commercial mowing).

* Prices in USD. Prices not adjusted for inflation, and will vary depending on geography and market conditions. Assumes regular OEM-specified equipment maintenance, regular wear and in good operating condition. Trade-in value of used LP mowers reflects soft resale demand and unknown engine life expectancy. Diesel mowers traded in after three years can typically provide several more years of useful service versus gasoline and propane mowers. Longer engine life expectancy of MaxTorque™ diesel reduces the need to purchase new equipment over time, which reduces demand for raw materials and strain on the environment.
5. Economical And Ecological Grasshopper Maxtorque&Trade; Diesel
MaxTorque™ Diesel provides significantly greater fuel savings, increases revenue potential and trade-in value with dramatically lower levels of smog-forming and greenhouse gas emissions compared to gasoline and LP, which is why MaxTorque™ Diesel is the perfect sustainability solution for any contractor, municipality and/or environmentally conscious consumer.
