Using some muscle last month to prepare a neglected (and falling apart) 4'x8' raised bed for planting (it had been unused so long there was a tree growing out of it).
One of the first purchases I made after moving to the country 18 years ago was a 7.5 cubic foot Rubbermaid utility cart, and to this day it remains one of the best things I've ever bought. We use it so much around the farm and garden that a couple years ago we bought a second one. (The cart pictured above is the older version; you can see our newer version in action here.)
The one-piece construction is incredibly durable and tough. They can be either pushed or pulled, are easy to clean, easy to dump, don't mind being left out in the weather, can handle rough terrain, and can haul up to 300 pounds.
Over the years we've used ours to transport everything from firewood to sick sheep. They're perfect for hauling manure from the barn, weeds to the compost bin, and grass clippings to the vegetable beds. I can't imagine gardening or farming without them.
We paid $189 for our second one several years ago, but right now they're available from amazon for just $139 each, with free shipping. They won't ship for 3 to 5 weeks, but if you're willing to wait, you can save a lot of money (the regular price is over $240).
I'm not sure how long this price will last, so if you've had your eye on one of these carts, now is the time to pounce. We're actually thinking maybe we should get a third one—that's how great they are.
P.S. These rugged carts can handle a lot of use and abuse, but I wouldn't, ahem, recommend throwing heavy pieces of firewood into them from several feet away, or turning them upside down and standing on them, especially if you're a very big guy. If, however, such a thing should happen while your back is turned, large cracks can successfully be mended with pieces of old metal license plates and/or metal strapping, preferably by the person who is responsible for causing the cracking.
Also, you can use your cart to move the generator, but take it out before you actually run the generator. Otherwise, the heat blasting out of it could melt a big ugly hole in the side of your brand new, shiny cart. Not that anyone would actually do this.
