The Compost Crank® makes it easy to "turn" green.. and brown! It penetrates any material like an auger. Crank the tool into your compost clockwise and lift without turning. Material clings to the spiral, pulling compost up from the bottom. You can thoroughly mix and aerate, or move material to active areas of the pile. The tool is easy for anyone to use and reaches every corner of the bin. It is also lightweight, so you are lifting the compost and not the tool. The free-spinning handles are molded to fit comfortably in your hands, and make the “cranking” motion a breeze! No jabbing, pushing, or prying necessary.

Past Reviews

“I just got this delivered last week. My initial impression couldn’t be better. The crank handle effortlessly moves the screw into the pile, and you have great leverage to pull up a plug of stuff from the bottom to the top. I’ve got a fairly large black plastic circular bin right now and in about 10 minutes of slight exertion I was able to give the pile the best turn it’s had outside of me using a shovel. Excellent, excellent, excellent. It was fairly easy for me to screw down too far, to the point where I couldn’t lift the plug, but reversing a couple of cranks solved the issue and a little patience let me get all the down into the pile.” - C. Chandler

"I bought my first Compost Crank more than 15 years ago in Brooklyn at a composting event. It is probably my favorite gardening tool because it makes composting so incredibly easy. I still have that first one, which is such a simple, elegant, sturdily-made tool that it works just as well as the first day I used it. I just bought a second crank so that I won’t have to transport my original one back and forth every week between my house and my summer cabin in the Catskills. I expect that I will be able to gift both cranks to my heirs!!! Well worth the cost." - Liz Miller

Great Product

I have some converted trash cans I use as compost bins, and this aerator has made my mixing of the bins much, much easier. Previously I had to empty the entire bin into empty containers and then refill while mixing. Now I just use the aerator a few times and it's good to go! Awesome. And I like that it's made in the USA.

Brilliant invention!

Love this tool! You wouldn’t guess just by looking at it just how effective it is. Can’t help wondering how the inventor came up with it. It aerates deeply and is easy to use. You turn it into the compost, pull out a plug of compost, and unwind in the opposite direction to release the deep plug onto the surface of the pile. Very hard to go to bottom with a pitch fork or shovel. Stainless steel, so I can leave it outside near my compost all summer!

I haven’t tried it for this yet, but I’m imagining it might work for planting bulbs in autumn, if not too many large roots in area....?


What an ingenious and elegant solution to the compost turning challenge. I no longer dread going out to the bin!

LOVE the Compost Crank!

I saw this tool being used in a YouTube video to help create compost in a month, which requires daily compost turning. My husband was previously using a pitchfork to turn the compost pile (ugh), but after one use of the Compost Crank, he was sold on its use! Now turning the compost pile is no longe a chore, but a fun activity!
