Our 3 gang Ultra 10 Fairway Roller has a 10 ' swath to provide 12 acres an hour of productivity at 10 mph – twice as fast as mowing! The new 5 gang Ultra 15 Fairway Roller has a balanced hydraulic system to keep ground pressure even over its 15 ' swath. At 10 mph, the Ultra 15 will roll 18 acres an hour – three times as fast as mowing! Both are tow-behind units. The Ultra 15 has a 150-gallon water ballast tank while the Ultra 10 uses a 100-gallon tank. –University of Massachusetts, Stockbridge School of Agriculture Ultra 10 Fairway Roller 1967 2017 5 0 YEARS More rollers with more features than anyone. Geunhwa Jung and Jay Popko Stockbridge School of Agriculture For years, rolling was just for greens. Today you could be in for a big surprise. Tests over a Two-Year Period Indicate Increased Rolling of Fairways can Reduce Fungicide Applications an Average of 50%. TEST SUMMARY • Plots were unrolled. • Rolled 3 times/week. • Rolled 4 times/week (Double roll 2 days). • Rolled 6 times/week (Double roll 3 days). Different fungicide spray schedules were tested (Threshold vs Calendar at 21-day interval) and initial results indicate rolling can reduce fungicide applications if threshold-based spray programs are used by 40 to 50%. This should be a major cost reduction if further test plots confirm this. Testing will continue next year on fungicide application as well as the effectiveness of rolling at reducing dollar spot, thatch and clipping yields.
