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).

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
Additional Revenue
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.
