Cleaning a wet ditch
n Ensure the articulation lock pins are removed before articulat-
ing, and install them when not using the articulating function.
n Articulate the grader so that the front wheels are in the ditch.
n Keep the tandem wheels on the shoulder to prevent wheel
slippage in the wet or soft material of the ditch.
n Side shift the circle and drawbar assembly towards the ditch.
n Tilt and angle the moldboard as required to move the material
out of the ditch and to deposit it between the tandem wheels.
n For the next pass, straighten the frame, side shift the circle
and drawbar assembly and center it under the frame. Position
and angle the moldboard as required to spread the wet mate-
rial over the shoulder.
