The Yoder YS640s is a heavy-gauge steel pellet grill with over 1,000 square inches of cooking space, built to smoke, bake, roast and grill for a crowd. Its custom-coded controller with ACS (Adaptive Control System) holds set temperatures and delivers strong smoke output from 150°F to 300°F, which owners rate above most pellet rivals. The Competition Cart adds a rugged, movable base, and the two-piece diffuser lets you run direct or indirect heat. It suits serious backyard cooks and competition teams who want set-and-forget convenience with real smoke flavor, and it is heavier and more expensive than mainstream pellet grills.

Owners praise the YS640s for its build quality, steady temperatures and deep smoke flavor, and many call it a step up from mass-market pellet grills. Common complaints center on weight, pellet consumption and occasional controller or app issues.
The Yoder Smokers YS640s is a pellet grill on a competition cart. It has over 1,000 square inches of cooking space for smoking, baking, roasting and grilling. It produces smoke from 150º to 300º. A custom-coded microprocessor controls the cooking for set-it-and-forget-it use.
The Adaptive Control System (ACS) connects to Bluetooth devices and a home Wi-Fi network through the YS Drive app for iOS and Android. From the app you can control the grill's temperature and monitor meat with the two included food probes. You can also switch to a cooking program that holds a set temperature once the meat reaches a chosen internal temperature. The board reacts to sudden heat changes, such as opening the door, adding 100 pounds of cold meat, or switching wood type mid-cook.
The ceramic igniter lights the pellets with induction heat. It lasts five times longer than conventional contact igniters, heats up twice as fast and creates 100% more heat. The grill sits on a competition cart with pneumatic tires for mobility, and a 2-piece diffuser is included.
