I have two gorilla carts - a 1200 lb capacity one I use for manure, and a 600 lb capacity that I use for everything else. I love them, much easier to maneuver then a wheelbarrow imo.
I love my gorilla cart! One of my best purchases ever. I put hay out in winter, move muck buckets, water buckets, even 2 round pen panels at a time. I also use it for just whatever else around the property. Mine is plastic, not mesh so I also pull behind the gator, full of dirt to fill holes in pastures or yard. Hand reverses for pulling. Get one (or two).
We had one like in the OP. We gave it away. The center of gravity was too high and it would tip easily. We used it at our house not a farm and we have a lot of terrain changes/hills. I hated it.
