First off they rotate clockwise. Looking at the Hub end. The house end trails behind. They are not like toys or a weather vain that will point itself into the wind. They are powered to turn to the correct angle of attack. If the house is into the wind something in the controls is busted. The blades also can change pitch to allow for wind speeds, shut down' and service. Now what you want to do is go on U-Tube and start watching all of the videos on wind turbines.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
