Integrated hydraulic chainsaw
Bar and chain are built into the grab body with their own oil tank. The saw cuts while the jaws still hold the tree, so felling, delimbing and cutting to length happen on the one hold.

Whether you know this as an excavator grapple saw, log saw grapple or chainsaw grapple, this excavator attachment is built for land clearing, forestry and storm clean-up. The Log Saw has a built-in hydraulic chainsaw, continuous rotation, jaw openings to 1,700 mm and cutting diameters to 640 mm, with a choice of .404 or 3/4 chain to suit the timber you are cutting.
Features
Continuous rotation
Rotate the tree to line it up for the cut, then rotate again to put it down. Logs land on the truck, the stack or the processor the way round you want, without slewing the machine for each one.
.404 or 3/4 chain
.404 pitch runs a narrower kerf: quicker through the stem, less sawdust, easier on the hydraulics. 3/4 pitch is the harvester-head chain for big, dense timber and hard, dirty work.
Hydraulic or electric installation
Hydraulic runs grab, rotate and saw on three auxiliary circuits with proportional joystick control. Electric runs one auxiliary through a supplied control unit and solenoid valve block.

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 GoogleMechanical 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.
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
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
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 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.
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.
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
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!
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 log saw grab? A rotating log saw grab, also called an excavator grapple saw, combines a rotating timber grab with a built-in hydraulic chainsaw. The grab holds the tree and the saw cuts it while it is held, so one operator can fell, delimb and cut to length from the cab. Three builds cover 5 to 25 tonne machines.
Do I still need someone cutting on the ground? No. The grab holds the timber and the saw cuts through it while it is held, so the cut happens with nobody underneath. It replaces the usual method of having a machine hold the tree while someone cuts it on the ground, which is why it is used for land clearing, forestry work and storm clean-up.
.404 or 3/4 chain: which should I choose? .404 is a 10.3 mm pitch with a narrower kerf, so less timber becomes sawdust, it is quicker through the stem and easier on the machine's hydraulics. It suits light and medium timber and a high number of cuts a day. 3/4 is 19 mm, the pitch used on harvester heads, built for big, dense timber and hard, dirty work.
What size log saw grab fits my excavator? Three builds cover 5 to 25 tonne machines and the ranges overlap, so machine weight only gets you close. The grab, the rotator and the saw each have a flow and pressure requirement listed per build, and a machine that cannot deliver it runs the attachment slowly. Send your machine details and typical stem size.
Is the installation hydraulic or electric? Both are available on every build. Hydraulic uses three auxiliary circuits and the machine's joysticks, giving proportional control beside something you cannot damage. Electric uses one auxiliary with a supplied control unit and solenoid valve block. Install is confirmed with our technician before order.
What is the maximum cutting diameter? 620 mm on the largest build with .404 chain, or 640 mm with 3/4. The 5 to 9 tonne build cuts to 400 mm and the 10 to 18 tonne build to 550 mm with .404. If your work regularly exceeds those diameters, tell us before you specify and we will give you a straight answer either way.
Log saw grab or log grab: which do I need? A log grab lifts, sorts and loads timber that is already cut, and is the cheaper tool for stacking and loading. A rotating log saw grab adds the chainsaw, so it fells, delimbs and cuts to length as well as handling. If the timber arrives cut, the log grab; if you are cutting it, the saw grab.
How much does a rotating log saw grab cost? Aussie Buckets rotating log saw grabs start at $34,985. Price moves with machine class and chain choice, and 0% finance is available on approved purchases. Every grab is protected by a 5-year warranty and lifetime technical support. Get a tailored quote against your machine.
