I use the term "wheel barrow" loosely. If it has less than 4 wheels, I call it a wheel barrow. I love mine. Both are 2 wheeled, one is huge, and has a dumping feature, the other one is smaller, and you just tip to dump. I can't tell you how many loads I've lost when using the single wheel style. I actually take them for a test drive before purchase. I had a guy at Lowes scratching his head one day. The garden carts were all locked up, so I couldn't test drive. So, I paid for the one I wanted, and he then unlocked them and sent me on my way with one. Well, after about 10', I found that the thing was not well balanced at all, so, I turned around and marched right back into the store to get a refund. They've gotta be well balanced, (and have good tires) or you'll expend way too much energy using them. An other thing... compost needs to be close to the ground so the beneficial soil organisms can move into it... IMO. Of course you could have it raised for better air flow, and inoculate with soil... but, I prefer to have mine on the ground. Better moisture control as well.
