Robust HARDOX 500 construction
The body and cutting areas are HARDOX 500, so continuous jaw impact and concrete debris wear the replaceable GET rather than the pulveriser. Tip force runs to 1,130 kN on the largest build.
Rotating Pulveriser
Available for 17 – 50T
American Eaton motor, continuous 360° rotation.

Built from HARDOX 500, this rotating pulveriser features an American-made Eaton hydraulic motor, optimised single-tooth jaw design and replaceable GET behind top-mounted access panels, for precise material reduction on standing structures.
Features
American-made Eaton hydraulic motor
Rotation runs through the whole shift, so the motor driving it is named, not generic: an American-made Eaton unit with an established parts and service network in Australia.
Continuous 360° rotation
The jaw turns continuously through 360 degrees, so a beam, column or slab is taken from the angle that gives the best purchase without tracking the machine round to meet it.
Reversed cylinder & manifold blocks
The cylinder is mounted reversed and the manifold blocks are optimised, keeping the hydraulics out of the path of falling material and simplifying hose routing on a rotating tool.

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 rotating pulveriser? A rotating pulveriser is an excavator attachment that crushes reinforced concrete and separates rebar, and turns continuously through 360 degrees so the jaw can be presented at any angle. Aussie Buckets rotating 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 to buy and run. A rotating pulveriser turns through 360 degrees so beams, columns and high work can be taken from the angle that gives the best purchase, without tracking the machine round to meet it.
What size excavator does a rotating 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. A rotating pulveriser needs a spare auxiliary circuit for the motor as well as the jaw. Send your machine details and circuit figures for a match.
What motor drives the rotation? An American-made Eaton hydraulic motor, running at 120 bar on 30 to 40 L/min. On a rotating attachment the motor runs through the whole shift and is the part that fails first when it is under-specified, so it is named in the specification rather than left as an unbranded component.
Can you replace the teeth on a rotating pulveriser? Yes. The top jaw plates, bottom tip plates and teeth are replaceable behind top-mounted access panels, so the tips and wearing faces are renewed as consumables rather than deciding when the jaw is retired. On continuous concrete processing that is what keeps the cost per tonne predictable.
How much does a rotating pulveriser cost? Aussie Buckets rotating pulverisers start at $32,875. 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.
