There always seems to be a lot of confusion when posters start talking about horsepower requirements and light, economy, medium, standard and heavy duty rotary cutters. Farmwithjunk's Post #10 really answers the issue. It does not take a lot of PTO HP to turn any size rotary cutter if the RC is balanced and in good condition. The HP is needed to cut the vegetation. This "Rule of Thumb" (that we all tend to use)was "gleaned" from the "Compact Tractor Bible" (2006)- "The power (required) is typically 2 horsepower per foot of cut for light-duty rotary mowing and 5 horsepwer per foot of cut for brush hogs capable of smashing 2-inch-diameter saplings." I would have provided more informaton about the book, but one can getter more useful information here at TBN and this information is free ! Jay
