The cart is still available however now only in black, where for whatever odd reason there used to be 2. Seach "gorilla cart" in the homedepot site and you will see. https://www.homedepot.com/p/Gorilla-Carts-600-lb-Poly-Garden-Dump-Cart-GOR4PS/206762393
I have the green one, G model. Here is my unprofessional opinion. The wheels looked bolted together on the PS. Two wheel pieces bolted to make a complete wheel. Three bolts hold the wheel pieces together. On the G the wheels are one piece. Formed or welded together. Take a close look at the wheels and you’ll see what I mean. Probably operates the same, but long term the wheels could collect moisture and rust, compromising the air chamber. tires may not hold air well when that happens. Eventually the wheels could break. Perhaps this is not likely. Anyway that was enough for me. Worth the $15, especially since I had a $25 gift card at the time :-) I’ve used the G model for all sorts of materials. The stack of car tires caused the plastic to flex, but no permanent damage. Let’s see, 2 years now of 200-400lb loads.
California is... No offense :-) Formaldehyde is frequently used in plastic manufacturing. It’s not the most healthy stuff. What little is left after manufacturing, slowly escapes from the plastic over time. Like new car smell, only new car smell is safe. Just don’t put the cart in a bag that would trap the gas and breath that gas for the next ten years. :-)
I haven’t, but I do t see why not. If you can lift the bags into the cart and mix, you should be strong enough to lift the cart to dump the concrete. I’d recommend rinsing the cart out after use. :-)
4 cubic feet when level but that is somewhat misleading as you can load over the top with most items like stone or top soil.
They may have one at your store but most stores sell out of them fast, you can order online from home or they can do it for you at the local store and ship it right to you, most items shipped free.

You could pull the cart with a mower though it is not designed for that. Just place the handle between the hook points and drop your pin in.
The handle is about 30" long and it is easy to pull the cart with that length, no bending needed. I have new joints as a lot of older folks do and this cart pulls easy, turns easy and dumps easy. You should have no problem with it.
Yes if the store near you has them in stock they do sell them assembled but note, they do sell fast, and they may have no stock left. The cart does assemble easily however.
