Abstract
A safety stand is provided for minimizing the effect of hydraulic failure in an agricultural harvester. The safety stand has a series of notches along a longitudinal edge of the safety stand which are designed to accept and received a protrusion affixed to a cylinder of a hydraulic cylinder which raises and lowers a feeder arm. When the feeder arm is raised, the hydraulic cylinder is in the full upright position, the safety stand can be lowered such that the protrusion enters and is held within a notch to prevent accidental downward movement of the feeder arm. If the notch fails, or the safety stand is not properly engaged, the longitudinal edge of the safety arm is allowed to follow the protrusion, until a subsequent notch is reached, which then engages the protrusion, safely stopping the downward path of the feeder arm.
