| 1. A method for reducing a torque load associated with an implement, the method comprising:
determining a speed associated with a power source, wherein the power source is configured to provide power to a hydraulic
pump;
determining a position associated with an implement system; and
limiting a flow associated with the hydraulic pump based on the speed associated with the power source and the position associated
with the implement system,
wherein the limiting occurs when the speed associated with the power source falls below a predetermined threshold speed and
the position associated with the implement system falls within a predetermined positional proximity of a stop point associated
with the implement system.
