Great Experience with this Machine

I’m a one man band on my ranch, and the Mudmixer has made it possible for me to complete small batch concrete jobs efficiently and effectively. The Mudmixer works as advertised. I like being able to turn it off mid job to move it or deal with the various things that pop up when you’re pouring a slab. With the Mudmixer I’ll be able to pave the whole place one 4x4 slab at a time!

Great to hear you are getting work done faster! Thanks for the review and your business.


John D. (Leonard, US)
Actually works as advertised

When I purchased the Mudmixer I was honestly a little suspect as to it working up to the hype. I’ve used it twice now, 36 bags the first time and 40 the second. Both times it worked perfectly, allowing me to change the mix with a slight turn of the water dial. One of the best features was the ability to shut it off for a few minutes when I needed to move the ladder since I was filling a concrete block wall. Then, turn it back on and back to work with the same consistent concrete mix.

Hi John, this is a great machine and well worth the investment. We appreciate your business and thanks for taking the time to leave a review.


Parts missing

Received an order 3 weeks ago with missing hardware. Still waiting for the parts.


Its unfortunate you felt the need to leave a 1 star review. We have responded very promptly to every email you sent the same day. As you know this in demand mixer has been on back order on and off. We did communicate with you the nuts and bolts were ordered the same day you let us know the hardware was missing. As soon as they came in we sent your package via FedEx overnight to you. I will apologize again, I am sorry you had to wait a few weeks to receive that backordered hardware. We feel like we did everything we could to get you squared away as fast as we could.

Best Service

Ordered a MudMixer. Wood Splitters Direct got it to me within a month due to backlog which was earlier than expected. From the customer representative to the warehouse personnel, they were very professional and problem solving driven. Even when delivering from FedEx cause an issue, Wood Splitter Direct representative Mike was on it to resolve the issue. Great work Mike! No wonder why their rating is good. I will recommend this company to my family and friend.


Hi Chai,

Thanks so much for the kind words. Glad we were able to get the shipping issue resolved fairly quick. I hope you enjoy the mixer, and thanks for taking the time to leave a review.


Boyd T. (Fresno, US)
Great Machine

This thing works as advertised. I don’t feel like it is a set it and forget it machine; it takes constant monitoring to keep the mix consistent. I’m not sure what causes small differences in slump from one bag to the next, but hand mixing probably won’t do much better.

I’ve run 65 bags through mine, and it does about a bag a minute. Bottom line, I could probably do a couple hundred bags in a day if I wanted. If I was mixing by hand or traditional machine, I couldn’t do that.

Thanks that is great to hear! Thanks for being patient on the back order on these machines. They are very popular with good reason. Thanks for taking the time to leave a review.

Jesse S. (Beaverton, US)

This has been the most amazing tool we have purchased in years. That’s saying a lot since I’m a tool junky. It definitely takes some getting used to since we normally order from a Readymix company. We bought the mud mixer to mix for doing fence posts on a job and it paid for itself in the first two days. I would definitely buy it again.

Dean H. (Uniontown, US)
Works Great

The MudMixer is a great tool for small concrete jobs. We used it for several months to mix more than 100+ bags of concrete on several small jobs with no issues and consistent results. We mix about 60lb bag a minute which allows one person to easily keep the hopper full. We also love the ability to mix on demand by turning on and off the machine when doing multiple small posts or filling block. When the work is done, clean up only takes a few minutes. Wish this was available 20 years ago!

Thanks for the review. These have defiantly been a popular unit. Makes it easy to do your concrete work!

Thank you, WSD

Delivers as promised

Great device to have in one’s arsenal…
We dig and pour hundreds, if not thousands, of footings and now my life has gotten easier with the acquisition of The Mudmixer….

Great to hear! This is one popular mixer, glad you were able to be one of the early ones to get your hands on one. Thanks for the review!
