If you ever look at the hydraulic cylinders on an 82 series and newer versus the quiet lines and older, the lift cylinders are different. 82 series and newer have a 3 inch stroke by approximately 2.5" bore. Quiet lines and older have a 6 inch stroke and approximately 1.25" bore. Obviously the cylinder with the largest bore will have the most lifting power if placed under the same hydraulic pressure, mechanical advantage, etc... Uppers feel free to critique this, but I believe Cub Cadet used a larger bore cylinder with a shorter stroke to allow the cylinder to be mounted lower in the frame for various reasons. This being said, the closer the working end of the cylinder is to the rock shaft the less leverage it has. Thus the larger bore is needed to overcome the decreased mechanical advantage. I have to cautiously assume the reason for the shortened stroke on the large bore cylinder is due to a law in physics as well. Newtons Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body. The closer the working end of the cylinder to the rock shaft, the further the travel of the working end of the rock shaft, i.e. deck lift and cam lift for blowers, blades, etc.... Again, making a guess, Cub Cadet did not lengthen the stroke of the cylinder due to either useable space inside of the frame or they were satisfied with the lifting travel. Sow any way that is my
