After using petrol shredders and chippers, this was disappointing. After a few years of use, it's still disappointing!

Short version:
Perfect for: gum tree branches
Slow and ineffective for: everything else (leaves, prunings, shrubs)

It's perfect for things like gum tree branches. It will pull in the branch and munch it up easily. Quiet enough to use in a suburban back yard without complaints from the neighbours. Also quite safe to use compared to the petrol shredders that I grew up using. If you mostly need it for things like this, then you...

I needed a shredder/crusher for the limbs and prunings around our garden. After much research I spent $100 more than I intended on this machine.

We had just had a flood go through the bottom of our yard and there were quite a few limbs washed up; the ease with which it took care of then was great.

Next was the dreaded Boganvillia complete with 3cm spikes which I had avoided for a year. Clipped it off 3 meter cane, fed the thick end into the chute and the Ryobi did the rest; did not have to guide it or touch the viscous thing again.

An excellent machine, does an amazing job and the bonus is free mulch for the garden.

I’ve been very happy with it for the past 2+ years but after some heavy work the counter blade (the adjustable plate opposite the rotating blade) cracked requiring replacement. After scanning Bigspares schematics of the machine I realised it is precisely the same as the Aldi Gardenline Silent Shredder SGS2500 (PLU 51383) which sells for $199 but only once or twice a year and my parents own. Turns out the Gardenline part was $24 off eBay and the Ryobi part was $59 but it works perfectly. So you can interchange all the parts between the Ryobi and the Gardenline. Maybe the Ryobi has a higher grade or tougher alloy in it but it doesn’t appear to make any difference whatsoever. Worth doing the research but in any case a great mulcher.

Great value Easy to use. Drags the timber in as efficiently as a much more expensive petrol engined unit ...It’s makes disposing of cutting fun and I had no difficulties adjusting the blades..

Was looking for a mulcher/shredder to cut down neighbours bamboos that were invading my yard. After looking around decided on the Ryobi RSH2445S model.
Heard people struggle with adjusting the blade but i found no issues with it. Followed the instructions regarding adjusting the blade until seeing metal shavings which then adjust again for 1mm and it worked fine. Cut down 100s of Bamboo sticks/branches with no struggles. If it did struggle, it would rev up the power. Self feeding is also good.
After two month of using, i'm quite happy with it. ...

I read some mixed reviews of this shredder but I thought I would give it a go.
The first thing is to get the adjustment right, do this with the motor running as when its stopped you can turn it too far and it will jam. Run the motor and look down thu the unit and you can see the gap, get it 1mm or so. Then it chomps and shreds really well. It self feeds (mostly) so there isnt much effort required to use it, I had an older shredder that you had to push everything thru and it was a lot of work to use. This is great.
The translucent tub is...

I have previously owned a decent petrol powered chipper/shredder that I put a lots of stuff through but decided this time I wanted something quieter and simpler. The Ryobi does a great job, as other reviews say it chops rather than shreds. Just what I wanted. Works great on long straight stems, branches, canes, palm fronds etc Not so good with crooked or wide splayed branches, you have to cut them into fairly straight lengths so they fit the chute. That’s about it, very pleased with what it can do for the price paid ($399)

It goes well, is very easy to use and a simple way to reduce your tree waist.

What it is:
It’s a chopper. It chips and chops your trees and branches into one to two inche pieces.

What it isn’t:

It’s not a mulcher and really doesn’t shred either.

it works best when the material you’re using is not fresh. I chop my trees and then leave it for a week to dry out. ...

I went to use it yest and it started and did few branches and then it stopped..
That was about three times in total ive used it since we bought it ?about 2yrs ago ..
We bought it from bunnings like we do nearly all tools.
It appears solid.,still looks new but we believe that the quality of items hve really deteriorated since being manufactured in china..
Honestly things seems to break dwn easily and made purposefully to break dwn just after bit of use..

I bought this to shred three cubic metres of freshly cut Cammelia tree, after my Ozito wouldn't do the leafy stuff. From reading reviews here, I was prepared that green leaves wouldnt be shredded, but was okay with that, as long as it didn't jam it.

Oh my goodness. This thing ate the Cammelia tree like the Langoliers from the Stephen King movie. I started by trimming branches from the main trunk. Absolutely no need. I was feeding entire 2.5m x 40cm braches in there, leaves and all, and it would pull everything in and chew it all up.

It jamm...

My Ryobi Silent Shredder worked perfectly, it shredded all I wanted big and small branches. However, I did wonder why the wood came out 'connected' with remaining bark. When I cleaned it after use, I found the pressure plate which is against the rotating blade was put in reversed, exactly as the manual says be careful NOT to do.
The overall performance was otherwise perfect.

great home shredder/mulcher
purchased the display unit for a good price
already assembled, not been used
Made short work of pruning from my bottle brush ttrees
You got to do a bit of pruning of side branches for the to fit in feed opening
Very pleased with it

My previous mulcher died and one of the things which irritated me was the mess. The Ryobi 'shredder' has a very useful catcher which keeps the mulch in one place and saves having to sweep it all up. It requires minimal assembly. It's fairly easy to move around. It is quite heavy and so having it in a permanent position and taking your material to it may be best for some people.

One thing it wont do well is mulching leafy ends of material. I mulched up Hibiscus branches and it worked a treat until I began to put too many leafy sticks through....

Product just over two years old stopped working because of a broken cutter blade.
Had very little use and no big stuff. Just out of warranty. There is no service centre within 60 Kim's even though I live in a large regional area.
Now have to wait some time just for a quote to get it fixed in Melbourne.
No more Ryobi products for me but staff at Bunnings were very good.

July 27th 2018 Update: Don't buy Ryobi from Bunnings

SHredder 2445T broke down just out of two year warranty. Bunnings will not help us and Ryobi is not responding.
No ...

Very good all round chipper,as stated by others not so good on soft stuff but then not made for soft material.Best things are twigs and branches just eats them up.Now The Not So Good Part......Try getting spare parts!

Great mulcher. Good for shrubs and bushes as well as palm fronds. It’s does not shred leaves it’s not for that. It made short work of 2 dead 8 foot pittosporums and a stinky Prostanthera bush called “Minty”. Good construction and easy to adjust. Recommend this if you have a medium to larger garden.

I am sorry to be agreeing with the negative comment here as I am having the same trouble. It seems that other comments have mentioned adjusting the blades. Yes I have read the instructions, but unfortunately I don't understand what I am undoing with the allen key?? Simple suggestions would be gratefully received.
This is likely the user at fault (me). I wasn't going to give a star rating because at present I am hating my new purchase, but if anyone can explain what I am doing with the allen key and how I adjust the blades so I can shred into small pieces I would be more than happy to rate it higher.

After reading mainly good reviews about the Ryobi Silent Shredder RSH2445t on productreview.com.au I bought this shredder yesterday and gave the thing a real workout today. Heavily pruned four 20 year old camelia trees and apart from a couple of very large branches the Ryobi munched it all with ease. Like others have said the blade adjustment takes a little working out but once I found the right setting the machine never missed a beat. Got tricked once or twice when the shredder would not switch on but one time I had the bin wrong way round and...

This was useless. Tried for an hour and adjusted blade at all settings. Did not cut or shred anything, had hedge clippings and just flattened and mangled them. Complete waste of 6 hours of my life as 2hr drive to go buy this Product from Bunnings as live rural. I have no idea how anyone could give favourable rating, I was shocked to see people do so. I wanted this to shred plant material to make mulch, did not do anything remotely like that.

Bought it yesterday and worked it hard today. Once you work out what the stupid Japanese cartoons are trying to explain and you set the paddle depth, it is the best muncher I’ve used. It is very quiet and slowly grinds whatever to a compostable mulch. If you see a negative review I suggest the writer didn’t open the instruction book. Brilliant, buy one!
