Portability Even if you never take your pellet grill on a road trip, you might want to move it from one side of the yard to the other when you’re having a party, or move it out of the way when you’re not using it. While some pellet grills are light enough to pick up and carry, wheels make the job easier. Of course, if you have a permanent spot for your grill, portability is less of a consideration.
You want to easily switch to different smoky flavors: Changing flavors in your Traeger grill is as easy as changing the pellets that you place in the hopper. Through its website, Traeger offers several different smoky flavors of hardwood pellet offerings, including hickory, mesquite, apple, maple, cherry, and oak. And Traeger’s website provides information on which types of hardwoods provide the best smoky flavor for certain types of foods, which can help you successfully use this grill immediately out of the box.
You like the idea of cooking different types of foods on the grill: If you’re someone who wants to grill food other than meat, the Traeger grilling system gives you this option. With the precise temperature control of the Traeger, cooking things like fruit pies can be a successful endeavor, something you wouldn’t dare try with a propane-fired grill.
Bought the Costco trade show model after about 4 years of debating the purchase... OK, first one broke on day one as "auger" stopped spinning. Returned and received a new unit. 2nd one smoked a turkey for 4.5 hours. After 4 hours temp. dropped to 100 degrees and it was set to 350. When I opened the smoker to check on why this happened, it exploded into a ball of flames! There was fire shooting out from all sides of the grill and smoke and heat coming from the feeder side of the grill... This was SCARY and could have absolutely caused a major fire, and/or injury!!!
The SG and ZG are not exactly the same though. Just from the pictures I can see that the bases are different. The SG has L-shaped legs and a bottom shelf while the ZG has square legs that are larger than the DLX legs but no bottom shelf. There were also different specs for many features. I took a picture of the ZG spec sheet at the store and compared it to the SG specs on the website and there are slight differences in capacities. For example ZG 3778 cubic inch - SG 4859, grilling area ZG 776- SG 811, hopper volume ZG 18 lbs - SG 22, ...
****Update 12/2014: So I finally found something negative to report. Today I was cooking 2 pork butts and a brisket and discovered that this grill does not do well with wind on a brisk day (It was 45 degrees here today). When set at 250 degree, the smoker could barely make it up to 190 degrees. I was able to bypass the problem by throwing a cheap moving blanket over the grill (an $8 fix) but I think it's worth noting.
We purchased our wood pellet grill (Model TFB57CLB) from Costco in August 2017. It came with one bag of the gourmet blend pellets. We used the Traeger cookbook to try a few different recipes in the fall. Most of these involve a period of smoking followed by a period of grilling. The grill seemed to work fine at first. We used it a couple of times on warmer days in the winter and it had some trouble getting up to the desired heat level. We started using it regularly again in April 2018. I was careful to clean it and check the pellets etc. The smoking feature seemed to work alright, but when I would turn the heat up for grilling, the grill would usually struggle to get much over 225. I would resort to turning it up to 375 or more just to get it to 225 and then often it would sink back down to 180 or 160. I went to the troubleshooting guide on the manufacturer's website and checked all the components, which seemed to be working fine.
To start using the grill, pour wood pellets into a hopper (pellets are usually are made from compressed sawdust). Press the start button to ignite the pellets, which are fed into the fire box with an auger, where a controlled number of pellets are lit and burned (depending on the temperature setting selected). The auger adjusts the number of pellets entering the fire box to maintain the desired temperature.
