The guys are pulling the forward transmission out of 172. You can see the rotor head with all the blades still attached sitting on the ground. It's riskier taking it off all together rather than pulling the individual blades off first then the head but if you have the experience to do it it makes things a lot faster. Our maintenance guys are doing a great job - most of them are still pretty new but they have the dedication to spend all day out there working in the sun.
