Respected professionals in the snow and ice removal industry have been testing and running studies on the Winter® Joma system for over a decade. There is no replacement for quality information from trusted sources. You can check the research for yourself.
| Source | Year | Type | Jurisdiction | Findings |
|---|---|---|---|---|
| Evaluation of Snow Plow Blade Systems, Final Evaluation | 2011 | Research report | North Dakota DOT | Joma blades lasted three to four times longer than carbide steel, although in the test one truck experienced a reduction in Joma blade service life when the blade angle was set incorrectly on the plow. |
| “Maintenance testing new blades,” Inside newsletter | 2009 | Anecdotal report | Iowa DOT | Blades tested in 2000 lasted an average of three times longer than steel blades, although Iowa didn’t implement them at the time due to cost |
| Joma Plow Blade Evaluation | 2010 | Research report | Lake County, Ohio | Joma blade life span averaged 6,000 miles since they were first installed on the county’s plows in 2005 compared to 1,000 to 1,500 miles for steel blades |
| 2010 | Research report | Franklin County, Ohio | Trucks equipped with steel blades required an average of 2.6 blade changes in the 2006-2007 winter season. During the 2007-2008 winter season, trucks equipped with Joma blades required an average of 0.5 blade changes, suggesting five times as many blade changes for steel blades as Joma blades, although service time and mileage were not reported. | |
| New Hampshire DOT 2009 Annual Report | 2009 | Anecdotal report | New Hampshire DOT | Projecting from five months of testing from the winter of 2008-2009, New Hampshire’s District 6 determined that Joma blades would last eight times as long as the department’s current blades. Further testing was planned for the 2009-2010 winter, but it did not happen due to the mildness of that winter |
| Clear Roads Product Experience Feedback for 2006-2017 Winter Seasons | 2009 | Anecdotal report | Illinois DOT | One Joma blade outlasted two sets of carbide blades in a single test. Follow-up comments in 2011 and 2012 reported that increased life span had continued. |
| 2008 | Anecdotal report | Milaca and Elk River, Minnesota | On one route, consisting of 14 miles of seal coat, 10 miles of microsurfacing, 5 miles of nova chip and 5 miles of bituminous, a Joma blade lasted 108 hours before replacement. A second route, consisting of 18 miles of seal coat, 25 miles of bituminous, 7 miles of concrete and 9 miles of microsurfacing, a Joma blade lasted 85.5 hours. On a third route, which was 45 miles of concrete in poor condition, a Joma blade lasted only 40 hours. | |
| 2007 | Anecdotal report | Utah DOT | In two tests, Joma blades lasted 124 hours and 108 hours compared to an average of 21 hours for traditional blades. |
