Would someone recommend a good gardening cart/dolly to buy for moving big potted trees around the yard like 15-20 gallon size nursery pots? I have a large dolly for moving refrigerators and large appliances, but it is just too big and clumsy for some of the narrow, bumpy paths in the packed garden. I was using a luggage carrier with larger wheels but it folds up too easily when I’m navigating around bushes and is breaking apart. Also, my lower back thinks it would be nice not to have to lift the pot to put it on the carrier. There are just too many choices on Amazon. I really don't need anything that folds up. From the reviews on Amazon, the fold ups have more on them to break.
What gardening cart do you use?

 I read other older discussions of this topic here: http://figs4funforum.websitetoolbox.com/post/plant-pot-mover-6171398?highlight=dolly&pid=1276543420

 Bill's Fig mover is too wide for my packed garden.

The Roughneck Folding Aluminum Hand Truck (600-Lb. Capacity) was suggested. But would this also be too big and clumsy for a little old lady like myself to use? http://www.northerntool.com/shop/tools/product_200586484_200586484

Standard dollies just do not work well as when you tilt them to move the potted plant, the top of the tree is literally in your face.

I mostly move my trees when they're dormant, so having a tree trunk to hold onto actually helps me stabilize them. I can move my face around the bare branches easily.

I use that one from Northern tools.  There's a bar across the back to keep it from folding up.  Don't slam that bar down and it'll last forever.  The long tang helps with wide pots.  It's not at all hard for me to use.  Next time you're in KC you can check mine out if you want.

My yard is so small I just drag ANYTHING over and its there!

Rcantor, the Roughneck is 19 inches wide. The hand truck I have now is 21 inches, which is too big to manipulate around my crowded plants and bumpy paths. The luggage carrier I’ve been using is the perfect width, 12 ½ inches, but it’s not designed for pots. The pots still have to be lifted up and over onto it. The collapsible handle keeps collapsing.

Northfig, I think the same would be true for your dolly, as nice as it looks. Lifting is still a problem for me. A good hand truck just slides under the pot, tilt, duck, and off we go….

I’m in physical therapy for a lower back condition. Yesterday I did what Meg suggested, drag two pots ten feet to a better location and it was too much. Ten years ago that would not have been a problem, but times change. I have to do something different. Thanks for your comments and suggestions.
