What should be the positioning of the blade in the parkline position?

The correct positioning of the blade in the parkline position is to pitch the blade all the way forward. This blade positioning serves multiple purposes, primarily safety and readiness for the next operation. When the blade is pitched forward, it reduces the risk of obstruction and allows for a more stable posture when the grader is parked.

If the blade were pitched backward or raised to the maximum height, it could pose a hazard to those around the grader or lead to unintentional movement while parked. Lowering the blade completely to the ground might be appropriate in some contexts but typically does not provide the stability and safety that a forward pitch does. Therefore, pitching the blade forward in the parkline position ensures the equipment is secure and ready for operation.
