Yoder Smokers Pellet Grills come standard with the NEW Yoder Smokers ACS Control System with two integrated food probes and ceramic ignition system are new features in the S series of pellet grills. With expansive cooking surfaces-ranging from 480 to 800 square inches-combined with nearly twelve inches of headroom, there's plenty of room for anything, including beer can chickens or turkeys. The cooker's main body and electronics are the same as the YS480, but when you add the competition cart and stainless steel prep shelves, it becomes even more versatile and markedly more maneuverable - perfect for someone competing at a different venue every weekend. The competition cart has 8" pneumatic casters, two of which lock the cooker into place, and a set of tie-downs to keep it immobile in your trailer.
