I recently picked up a 47" (refrigerator) 2 stage blower. Good condition but needed some more features, one thing I noticed right away is no feet towards the front and it dug in the gravel. Second thing was I enjoyed the hydraulic chute rotation control (a lot!) and decided I needed to have the spout angle control to complete it. I ordered the JD actuator kit from Firgelli Automations that comes with the actuator, cover, limit switches, wiring kit and a switch (although I went with lighted rocker).
