Built from HARDOX 500, this excavator pulveriser combines a single-tooth jaw design, replaceable cutting blades and reversed hydraulic protection for structural demolition, rebar recovery and predictable running costs.
Features
Reversed cylinder & manifold blocks
The cylinder is mounted reversed and the manifold blocks are optimised, keeping hydraulic components out of the path of falling material and simplifying hose routing.
Balance & speed valves
Integrated balance and speed valves on every build stop the jaw drooping under load and shorten the close cycle, so more material is processed per hour of machine time.
Single-tooth jaw design & cutting blades
The single-tooth jaw concentrates crushing force to break concrete efficiently, while integrated cutting blades shear the rebar inside it. Rubble one way, clean steel the other.
Technical Breakdown
Four build sizes covering 15 tonne to 50 tonne machines. Weight, jaw opening, width, jaw depth, tip force and middle force are listed for each build.

Built to fit the machine you run
Nothing here is an off-the-shelf pattern that you have to make work. Every unit is manufactured to your machine's tonnage, hitch and pin centres, so it bolts up to Caterpillar, Komatsu, Hitachi, Kobelco, Volvo, CASE, Kubota, Yanmar and Takeuchi alike. Send us the make, model and pin sizes and we match the bracket before it ships - if your machine isn't on this list, it still fits.
What they say about our gear
See all reviews on GoogleRock Breaker & Mud Sieve Buckets
After receiving our first order which had a rock breaker and some mud sieve buckets we knew we'd come back for more, just placed the 3rd order, great service and advice from the sales team, the quality and finish of the attachments are better than I can get locally and a better price.
Rock Breaker
Good service answered any questions i had about matching the new rockbreaker to my machinery. And does the job intend for. Prompt delivery and hassle free. Definitely recommend Aussie Buckets.
Mechanical Grab
We bought a mechanical grab for 20T excavator. Good communication during the whole process via email or phone. Good quality product which we haven't had a problem with at all. They also offered to help install when we picked up but was not required. All departments from order to pickup were very helpful.
Rock Bucket with Ripper Tooth
Great rock bucket. Very effective for separating large rocks out of fill material. The ripper tooth is solid and well fabricated. I am very satisfied with my purchase after several weeks of use.
Ripper & Rake
Recently bought a ripper and a rake for a 8ton digger, both great quality attachments. The guys at Aussie buckets are very easy to deal with, straight forward for ordering and purchasing. The rake is great for any job in grass or vegetation, even when mixed with rocks or rubbish.
Auger & Drive
Purchased a new Auger and drive with Aussie Buckets. The whole process including checking my dimensions I provided were correct was very easy, even for a backyard excavator operator. Now making tree planting and farm fencing a breeze.
Grab Bucket
Purchased a grab bucket through Aussie Buckets. Andrew and the team were super helpful and very thorough with all the measurements, information and communication. Bucket arrived today and have easily attached and straight into work. Super happy and will purchase more attachments with Aussie Buckets again.
Hydraulic Grab
Recently purchased a hydraulic grab for my mini excavator, great piece of equipment, great quality and pricing also customer service was fantastic. Easy partial assembly required, great bit of kit.
Hydraulic Grab
The hydraulic grab is better than any Christmas pressi. I use it on my farm dealing with trees and firewood. Also pipe laying. Try lifting 450 dia 12m long HDPE pipe and the grab fits perfect. OK the little Kubota knows it got a big fish on the hook but I can do what I can't do otherwise. Great choice - by me, great product thanks to you.
Rotating Grab
Great product, great service, Nick made the process very easy. The rotating grab has been an awesome addition for our scrap metal yard. Cheers from YP Recycling
Tilt Hitch & Auger Drive Package
Have bought a tilt hitch and now an auger drive package through the team, can't fault them at all, from Hayden in sales to the whole team. Will definitely be purchasing my equipment through Aussie buckets in the future
Hydraulic Grab & Auger
Great company to deal with. Excellent quality hydraulic grab attachment. The company was so nice to deal with I placed another order for a different attachment. Also kept me updated on my order from start to finish. Received my new auger and it is an amazing piece of kit coupled with a 350mm auger and I got the 1m extension also. Had a bit of time to test everything out and the grab is great for moving posts rocks and anything else to save my back. The auger has plenty of torque and because I'm in a bit of rocky ground I got the combination auger and it's busting through it quite well. Still very happy with my order and Aussie Buckets support and after sale check in just to see how everything is going.
5 Finger Grab
Great team at Aussie Buckets. Very helpful and thorough in getting the correct dimensions. Regular updates on manufacture progress. And the 5 Finger Grab fitted perfectly and wow how powerful and useful. Tripled the use of my little 1.6 Takeuchi.
Hydraulic Grab
Huge thanks to Hayden and the whole team at Aussie Buckets!! Great price and really fantastic service. I purchased a hydraulic grab for my 305CR, great communication from the team throughout the order and delivery process and the attachment went straight onto the machine effortlessly and is very well built! I have already ordered a ripper and will be saving up for a stick rake next!!
Hydraulic Grab
We bought a hydraulic grab for our 5t excavator from Aussie Buckets and couldn't be happier. The square edged jaws help with gripping material while filtering out the dirt. So far, our customers have loved using it
Heavy Duty Stick Rake
I recently took delivery of the 1200mm wide heavy duty stick rake from Aussie Buckets. I was very impressed with the price I received and the staff kept me up to date during the procurement process. I love the design and the quality. I would very much recommend this product and I will look to source some more attachments through them in the future!
Hydraulic Grab
We purchased the hydraulic grab for our Kubota 1.7T for the purpose of moving rocks and logs which it does with ease. Exceptional design and construction I would highly recommend Aussie Buckets.
Rock Hammer
Needed a new rock hammer. Aussie Buckets delivered a quality product that is exactly what I required. Definitely would recommend
Frequently asked questions
What is a concrete pulveriser? A concrete pulveriser is an excavator attachment with powerful jaws that crush reinforced concrete and separate the rebar from it. It is also called a concrete crusher or demolition jaw. Aussie Buckets fixed pulverisers cover 15 to 50 tonne machines across four builds on a HARDOX 500 body.
What is the difference between a fixed and rotating concrete pulveriser? A fixed pulveriser presents on the orientation the boom gives it and costs less. A rotating pulveriser turns continuously through 360 degrees, so a slab, beam or column can be taken from whatever angle gives the best purchase without tracking the machine round. Structural work is where rotation earns its cost.
Pulveriser or crusher bucket: which do I need? A pulveriser reduces concrete and separates rebar for disposal and steel recovery. A crusher bucket produces graded aggregate you can reuse or sell on site. Choose the pulveriser to get the structure down and the steel out, the crusher bucket when the output has to be a usable product.
What size excavator does a fixed pulveriser need? Four builds cover 15 to 50 tonne machines, with jaw opening from 700 to 1,000 mm, crushing force, weight and flow requirement listed per build. Pulverising loads the machine at reach, so lift capacity matters alongside weight. Send your machine details and the structures you are processing.
Can you replace the wear plates on a pulveriser? Yes. The top jaw plates, bottom tip plates and teeth are interchangeable, so the faces that actually wear can be renewed rather than the jaw reaching the end of its life with them. On concrete processing the plates are the consumable, and specifying them that way is what keeps the running cost predictable.
How much does a concrete pulveriser cost? Aussie Buckets fixed pulverisers start at $28,675. Price moves with machine class and jaw capacity, and 0% finance is available on approved purchases. Every build is protected by a 5-year warranty and lifetime technical support. Get a tailored quote against your machine.
