LEGO Technic Off Road Utility Truck (ORUT) MK2 - Tine Aerator

This is a new attachment for my LEGO Technic Off Road Utility Truck (ORUT) MK2, this is a rear mounted tine aerator. These are used at sports ground to aerate the soil, to allow water and fertiliser to get deep in to the soil.

This is mounted to the rear of the tray and uses the rear PTO to drive the axle, which has a pair of 3L thin beams, this rotates and causes the arms to go up and down, as it drives along. It also has a mechanism to lift the arms, to stop them going up and down as it drives along. I tried a few different methods to do this and found this one, which lifts the arms clear of the 3L thin beams to be the best.
