The original corkscrew compost aerator!

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.

"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

The best!

I love my compost crank! They're exactly what you need in a top-loaded bin like a cut-off garbage can. I gave my first crank to a friend last year when I moved to a place that didn't compost, so when I moved and started composting again, I was excited to buy another, and it works as well as the first.

Revolutionized my composting!

I inherited a languishing composter in the backyard of my new home. I already had my preferred 'tumbler' style composter, so I honestly wasn't too excited about this bin of... stuff... to manage. When I stumbled on an ad for the Compost Crank, I thought maayyyybe it could get my bin activated so I bought one. OMG, the Crank is AMAZING and I'm not exaggerating. Within two weeks of regular cranking, my bin was outperforming my 'tumbler' with regards to heat and overall activity. Plus, it's just so darn simple/fun to use. I first chuckled over the note in the packaging saying 'may cause raving to friends and family... and then within weeks I actually WAS raving about it, dragging folks out to the bin to try it out, etc... LOL. Even my 75 year old mom gave it a try and couldn't believe she could sink that Crank to the bottom and turn/lift without an issue (I just bought her one for Christmas, shhhh!) Buy this thing. You will not regret it.

I love my Compost Crank

I just used my crank for the first time today. It works so well! It is easy to use also.

Best gardening tool. I'll be out compost cranking!

I learned about this tool from a woman in my university extension composting class. The instructor hadn't even heard about it but this woman raved about how well it worked for standing (not tumbling) compost bins. I have two large standing compost bins (besides my two tumbling bins) and trying to turn the compost with a shovel or pitchfork was difficult at best. This reminded me of how an ice fishing auger works and seemed like it could be a really effective tool.
This was expensive but I put it on my wedding registry and received it from a (great!) friend. I love it. Aerating and turning the compost is so easy and fun. With a large garden, I take composting somewhat seriously because, even with chickens who contribute to the bins, I never seem to have enough compost, so I am always in demand and looking for last season's compost to be ready ASAP.
This tool is a great help. It is just so easy. Dig down too far and can't pull the tool out? Just un-crank it until lifting it out is easy. Now I try to spread the news of the compost crank to all my gardening friends and soon-to-be composting converts!

This Crank really WORKS.

I’d rate this compost crank with 10 stars if I could. My bin was over 1/4 full and had defeated a friend’s claw-type aerator. As a small (5’), vintage (85) woman, strength is not my strong suit yet I was able to work the Lotech Compost Crank down to the bottom then pull it up churning the the compacted mass. I about danced around the yard. Thanks, Lotech.
