The reversible and replaceable edge dramatically extends the bucket's lifespan. This reduces the need for regular maintenance, driving down unnecessary maintenance costs.
Dual radius profile
Processes more materials per fill, eliminates drag from the bucket and improves digging efficiency.

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 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.
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.
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.
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.
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
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.
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
Frequently asked questions
What is a sieve bucket? A sieve bucket is an excavator bucket with a screened floor and back that separates fine material from oversize as it loads. It is also called a skeleton bucket, riddle bucket or rock separator. Aussie Buckets sieve buckets cover 1.2 to 50 tonne machines with screen spacing built to your material.
Mud sieve bucket vs. rock sieve bucket: what's the difference? A rock sieve bucket is built for sorting soil, rock and waste, with high-penetration teeth, on 20 to 58 tonne machines. A mud sieve bucket is built for separating finer material, soil, subsoil and fines, from 1.2 tonne up. Rock and waste take our Rock Sieve Bucket; soil and fine material take this one.
What is a sieve bucket used for? Separating topsoil from rock and roots, recovering fill from demolition spoil, pulling rubble out of trench backfill, and site clean-ups where the fines are worth keeping. It turns a load-and-cart job into a screen-on-site job, which is where the cost is saved.
What screen sizes are available? The mud sieve bucket's interlocking rib and rod screen is available in customisable sizes from 60–150 mm and beyond, so you can match the screen to the material you're separating without ordering a different bucket.
What size excavator do I need for a sieve bucket? Our mud sieve bucket range covers 1.2–50T excavators across eighteen builds. Get a tailored quote and we'll match the bucket and screen size to your machine and the material you're working.
What is the difference between a sieve bucket and a screening bucket? A sieve bucket screens passively as the bucket loads and shakes, with no hydraulics involved. A rotary screening bucket drives a powered drum, screens continuously and produces a cleaner grade at higher volume. Choose the sieve bucket for occasional separation, the screening bucket for production.
How much does an excavator sieve bucket cost? Aussie Buckets mud sieve buckets start at $1,240. Price moves with machine class, width and screen specification, and 0% finance is available on approved purchases. Every bucket is protected by a 5-year warranty. Get a tailored quote with your machine details and material.
