So addicting and then you find yourself shopping for the materials

[@cheritait8116]

Yep!

[@gabbygertie8709]

As a 70 year old handicapped grandma this is absolutely the answer to my prayers! I have been screening my compost by hand and it takes hours of backbreaking effort. I already have the cement mixer so this is going to the top of my husband's honey do list! I can't wait and neither can my back!

[@JG-fg1ye]

This is the best design I have seen so far

[@ussweeneyd]

Only a brave man films the first try out. Great job and good project.

He's not only brave, he's confident and aware there are always minor and sometimes major adjustments

Every once in a while you run past the video that's like takes your breath away and this is definitely one this this this this this this this helps me out so much on two fronts I thank you for your time😮😮😮😊

[@bethatz252]

I can hardly wait to show my "non-gardening" husband your invention. I think he'll make it for me because you did a great job of demonstrating how to do it. Thanks.

[@JasonEyestone]

I clicked the like button right after I heard “you can also use it as a soil mixer”. Thanks nice video

[@Bearclaws1234]

This video is awesome. This has got to be one of the TOP KZbin / DIY type videos I’ve ever seen, and I watch a lot of KZbin. Great outlining and presentation. Hats off to you!! Keep ‘em coming! Thanks!

[@chri8067]

I'm 10 seconds into the video and saying this is an excellent idea and project.

[@kevchard5214]

I am a big fan of multipurpose tools and have looked at a mixer for a while now but couldn't justify a single use tool. With your genius idea I now can justify a mixer. Thank you very much!!!!!

[@badeadrian]

That was an amazing idea... Excellent work 👍

[@mobyindisguise]

You Sir, are a genius, superb thinking outside of the box and you've still got a cement mixer to boot!

[@smokymountaingirl]

researching ideas all day for my newly worm casting farm and harvesting project and this is EXACTLY what I am going to do if I can find someone to help me.

[@andrewehrmantraut4742]

This is genius!!! I wish I had this yesterday when I sifted my compost for my beds and pots. I like how you didnt edit out the mistake, made me lol and proves you're still human! Either way, freakin genius.

[@alexballstoyou6335]

@@mrgallbladder what?

[@nelsonolivera8059]

I think you are a genius because you were able to simplify it to the point that I might take a shot at building it. Thank you for your generosity, clarity and for being able to teach. Namaste, Nelson

[@davesims3471]

Absolutely love it! I've been kicking around ideas in my head for a while now and this NAILS IT! Already have so many ways to use this around the gardens! Now to convince the wife I need more garden tools!

[@that_auntceleste5848]

See and here i am waiting for my husband to retire so he can build me one! 😆

[@markjust86]

​@@that_auntceleste5848 and I need a wife to tell me that I can or can't make one! 😂

[@lillysimeoni5080]

I bought the same concrete mixer when it went on sale for Christmas specifically to mix soil and make aircrete. I use vermiculture, compost, humus, goat, rabbit, duck, chicken and quail manure to make my own soil and needed an easy way to mix it all for different uses. Your idea is an awesome implement for me, def will make it! Planting season is in full mode now and I can’t seem to mix soil fast enough to plant and mulch all my gardens. Thank you for the video!!

[@IowaKim]

I love this idea, especially using a mesh trash can.. I already have a cement mixer and you have given me the idea to trundle that out to my compost yard and use it for sifting and combining materials. Thanks much!

[@WaddedBliss]

That sifted compost at the end is brown gold. Beautiful.

[@solidsoldier9021]

GREAT JOB SOLDIER 🪖, HARBOR FREIGHT HERE I COME.

[@MarkBohland]

Thank You! I am not mechanically inclined, so something with simple instructions and simple processes like this is invaluable. Thanks Again!

[@mindy779]

Wow you are the MacGyver of gardening. This is a most excellent project. Thank you for the instructions. 😄👍😄

[@downundervlogs]

What a fantastic way to harvest compost. I have to say I really enjoyed sitting back watching you do all the work shovelling the compost in, I was quite mesmerized by watching it turn and sift. Great job.

[@markluke8447]

Thank you Dan, for sharing your projects. This is a good idea and to see your building process helps us all in doing our own. Good job, great video. Thank you.

[@t.barclay203]

Wow! What a clever idea and execution!!! You are a gifted teacher. Thank you!

[@NatalyaBerezneva]

Thank you so much for sharing! We are going to make one ASAP. This is must have for all gardeners and small farms.

This is so genius! Wow. Looks like a pro tool one could buy! Thank you for sharing!

[@jacklong311]

I love that you were not afraid to show you errors. Good job and what at great machine.

[@dmwark]

serious sifter envy here

[@matsvineyard7564]

the best version of a composter I have seen yet,

[@MikeKincaid79]

That's ingenious! I've got to put one of those together, thanks!

[@bigdogbob845]

Nice Dan ! ! ! Looks like you re-purposed a cement mixer. I made my own 10 years ago, it is 6ft long with 4 ea x 27" bicycle rims to support the 1/2" mesh heavy wire drum, swivel casters on a wood frame and an old washing machine motor for power, works great. I even lend it out to neighbors who have compost piles, they love it too.

[@corinneyeager]

Thank YOU ‼️‼️‼️

[@that_auntceleste5848]

Howdy Neighbor! 😂

[@Mityob67]

Love it when a plan comes together! Great content, thank you sir!

[@bracebridgelionsclub5223]

Thoroughly liked this video. So informative, clear, concise and helpful. I especially enjoyed the professional grade production values and choice of music. As a beginning vermicomposter, I have struggled with the question of how I will create a trommel when the time comes and now I have an answer. Thanks.

[@sumerbreze46]

I brought my harbor Freight Concrete mixer to mix my ingredients for potting soil. I did see this idea before, but your setup with the metal mesh trash can is and wheel casters is better. Great Job!

[@debraarizona4809]

That is another awesome invention,you thought of everything.✋[high five!👍 I can think of several ways to use the machine.💕💕love it!!💕🤗 I like my potting soil,and garden soil sifted,and free of twigs,rocks,etc. I don't have to sift by hand now! 😀 This creation is another stroke of genus!!! Fabulous!creation,well done.👍🤗🌹. Excited!! to save and get one put together.🤗🤗 Thank you for sharing Genus😁

[@Anvil-Blacksmith]

I have made one 2 years ago i drilled no holes in the trommel and i have screwed a piece of wood at the mixer foot to improve the stability of the mixer . This is also a nice idea ! Happy sifting!

[@grahamedwards9634]

1 Minute in and this is brilliant needed this 8 years ago to do the soil thumbs up from me

[@vlvtopcat]

Awesome job thinking outside the basket lol.Works great.A great multi use tool.God Bless

[@herbkronholm2781]

Thank you for sharing and all the information. I built this same unit this past summer with some slight modifications and it works perfectly. A Milwaukee m18 leaf blower keeps the 1/4” mesh free and clear of wet mulch during operation. Thanks again as you saved my back along with valuable time.

[@Rec_it_Roop]

one of the best i've seen. simple. easy.

[@twinpalmsvideo2741]

as a new gardener, this vid is an inspiration. I just bought some dirt, peat moss, etc. and I was thinking how to mix it. I never thought of the cement mixer, which I also have an old harbor freight mixer. Thanks.

[@tombouie]

Well Done & Communicated. Minor important: Remove the TOP half of the mixing drum/tub & mount the sieving drum/tub onto the BOTTOM half.

[@RustyCarnahan]

I use one of these cement mixers as a livestock feed mixer. A setup like this could also serve as a grain cleaner. Food for thought

[@debmartindale6991]

What an ingenious compost sifter!

[@jamesc9327]

You did an awesome job on your soil sifter sir. I wish to thank you for sharing your experience and video on KZbin. I can't wait to build incredible soul sifter. Adding the 1/4" mesh was an excellent idea. 👍👍👍👍👍👍👍👍👍👍

[@santiagomercado4523]

What a great idea! Very nice way of using one machine to do 2 different task. Thanks.

[@dsbennett]

Excellent! Except that I read a comment for a different mixer that cost around $170 where the person said he bought that one after reading comments about this mixer. I didn't even know there was a basket like this. Perfect!

[@doctoreden]

Brilliance is in simplicity! Excellent idea.

[@veronamartin5285]

My partner has worked in concert finishing for almost 20 years. Last year we moved in together and he brought home a huge load of garden dirt that a client didn’t want anymore. The garden was removed to make room for more parking. He dumped it in a pile in our backyard. I used to work at a Hotel years ago and they changed out their furniture. Staff we’re allowed to take the old furniture home for free once they had sold what they could to the public. I took the Queen sized headboards home. They came with me wherever I went. So I used 8 to build two garden boxes and filled them with the same dirt he brought home. I have enough boards to build two more but not enough dirt. The pile that was leftover ended up growing grass & weeds. I covered it with a tarp & rocks to help kill them. I’m going to ask my partner to bring a cement mixer home so we can put something like this together. This will help shorten the waiting process and I can always build the two boxes & add dirt as I get it. The garden boxes are doing amazing and I have been outside all summer making improvements to the yard. I’m mostly fixing the stuff given to us. I can add the garden boxes, dirt & weed fabric to the list of things we have gotten for free. I call it free-cycling. ❤

[@DeeJayBee85]

Wow! Works great and appreciated letting us see the necessary modifications😄 you make it all look so easy! Very encouraging💕
