Sunnybrook makes a cylinder with the rub bars cut into small pieces and staggered instead of one long rub bar. They claimed much greater separation in crops like barley, and lower horsepower requirement. This may be true, as JD has long insisted that in its pull type line of forage harvesters that 48 small knives takes less power than 12 full length knives. The local dealer says to be leary of the solid cylinders because they have no give when wads come in, so the concave takes all the abuse. Apparantly lots of concave hangers broken from solid cylinders being used.
