Abstract: A hold-open mechanism for a canopy of a skid steer loader machine is described herein. The hold-open mechanism includes a support block secured to a frame of the machine, a wedging block secured to the canopy, and a prop device. A bracket is connected at a body portion to the support block and extends therefrom for termination at a head portion. A pair of arms extend perpendicularly from the body portion. The prop device has a bar with first and second end portions and a lever connected to the bar and supported within the arms of the bracket. A biasing spring is positioned on the bracket adjacent the bar for biasing the prop device to a working location from a resting location. In a closed position, the canopy is forced against the biasing action of the spring to maintain the prop device in the resting location.
