I would still have 3.5 inches to lift the pots onto the platform. That's a lot of maneuvering for a senior citizen!
And I was kidding about the cart/dolly. They are both used as dollys, but called two wheel carts here. I love the Worx Aerocart. I use it for all garden jobs. DD give it to me for birthday. At first , I didn't read the instructions and only used it for mixing soil.
