Our well respected and popular YS640s is just at home on the competition circuit as it is the back yard. The YS640s competition pellet grill comes fully equipped with the NEW Yoder Smokers ACS Control System with two integrated food probes and New ceramic ignition system. The cooker's main body and electronics are all the same, 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
