$ 70.75

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

When you dream big and build compost boxes larger that one cubic yard and then try and turn your compost pile with a pitchfork can be a lot of work.
I purchased a Compost Crank in hopes that it would save time and energy turning over the compost. You know what? It made the job much easier. It helps to start with short crank and pulls, as the compost loosens up it becomes easier to get all the way to the bottom, pull up and compost is turned. Great upper body workout as well!

What a handy tool!

I just bought an open compost bin and wasn't that thrilled with my options for turning the pile. And I didn't feel like buying a pitchfork, which would only be used for this task. So, I did a search and found this company, and look! It's right here in Tucson! I ordered a Compost Crank, which arrived in a completely compostable package. What's not to like about that? Using the crank, don't tell anyone, but it's a lot of fun. To the point where I actually look forward to turning my compost!

Easy Work

I love using the Compost Crank. It is easy to use and makes aerating the compost much easier to do. I am using it in a 3 x 3 foot bin and also my plastic Earth Machine bins. Works equally well in either application.

Thank you, Lotech!

Years ago as a new composter, I started out stirring my compost with my tiller--I saw that pro tip on the internet--but soon realized I was mass murdering the worms. I love worms. So, I got a shovel, which mostly maimed the worms. Hard work, but effective. Then I learned about turning forks and that was a vast improvement over the shovel for turning my pile. Then I got the compost crank. This is a genius invention. So easy to use and it works so well! I use a Geo Bin composter; a complete turn involved moving the whole pile which was neither easy nor fast. With the compost crank I can turn my entire pile in under 10 minutes. Seriously, do yourself a favor and get this. You will not be sorry!

Only tool you’ll need for compost, mixing soils, everything.

I bought a new one in case someone steals. One. It has happened twice to me in my teaching as a master gardener!
