This is absolutely useless. Bought it to shred some shrub clippings, really light stuff no more than 11mm thick. Was easy to assemble but that's the… Read more

only positive. The feeder constantly blocked, and after a while the exit chute would block too. Had to constantly turn it off to clear jammed material. I calculated it would take hours to process, so instead I got the lawnmower out and ran it over the lot and it was done in 10 minutes. So the supposed purpose designed machine failed where the humble mower designed for something else left it for dead. Completely unfit for purpose and very poorly designed. Don't buy this junk !

so (anything bigger is firewood) self feeds and spits a mile. It's the only one I know that truly eats fronds. I have a bamboo wall out back and use it shred the lot for the green bin or tip. It can at times get stringy bits wrapped around the disc, but undo 2 bolts & it's easy to free - my fault in the first place. For anyone who has problems with it, check your technique it's usually operator error. I do service it regularly and it never misses a beat. The knives are easy to remove and sharpen with most of the issue being sap. Just make sure the gap setting is right when you refit, and remember chippers are meant for green not dried cuttings. Changing the belts is simple enough when you get the hang of it. I love it.

Posted on Ryobi Feedback also ago I bought my Mulcher maybe three years or so. It mulched branches and leaves for three autumns until this week when… Read more

the smaller branches ended up clogging up the system being crushed not chopped. I looked online for parts to fix the shredding mechanism and was surprised to find that they were NLA. I contacted Michigan who have a similar 2400 w mulcher, to see if their parts would fit but got no joy. So armed with this I raised the issue of parts support with Ryobi and Bunnings the manufacturer and my supplier. Surprise came when I was referred back to Bunnings by Ryobi Customer Service with an RMA. Bunnings gave me like for like a full replacement valued at $499 after three years of use thanks to Ryobi. No questions asked. When I got the new mulcher home I did notice that a disclaimer on the box states that the four year warranty relates to full replacement. They do not have a servuce department, choosing instead to rely on the product quality. Now depending on your point of view and the Consumer Affairs requirement for any product that is sold carries a warranty, it woukd appear that if you gave an issue with a Ryobi product especially high value, they don't impose any conditions much. Again surprised to come home with brand new mulcher value $499 and four year warranty, You can't ask for better than that can you? . Thank you Bunnings for the ease of returning the worn item and replacing it. A better than fair outcome.

Great machine as the conical shaped open bladed both cuts, drags and also shears against the stationary blade. Its conical shape results in the… Read more

clearing of the rotor. As a plastic recycler once, I had many cutters and the design of the Bosch 23 is very clever and its blade endurance has been terrific. The stationary blade can be adjusted easily by just turning a black knob. I have had my unit for over 10 years, and the blades are as good as new. But it will build up with soft leaves so keep woodier bits ready to pull the softer stuff through. Big flowers won't get pulled through - and heavy leaves also will not get through. They'll build up and block the hopper, and you'll have to open up the hopper and free things. Reversing also assists. It is safe due to only working when the feed hopper is closed. For hedges and tree branches this unit is incredible. It mostly self feeds. I had an Ozito mulcher which wore out quite quickly. However I dropped the Bosch removing from an SUV to do my father in law's large hedge, and the Bosch fell onto the road, and cracked an internal part of the housing. One has to be careful that it is not designed to handle a fall! Bosch in Australia had it repaired (it was 5 years old and I paid for the repair) but they could not source part, so they made up a part from timber, which eventually failed. The machine still works fine mechanically but the safety switch can not always connect, so I am having to buyer another one. Its price has been maintained over the years as i paid over $Au700 ten or more years ago. If one is moving it - remove the top completely, do not bundle it as a single unit. The top can be stored in its mulch container, which makes its compact, but also, that is the way to transport it, in separate bits. The rest of the mulchers are much lower in quality or very expensive (ie petrol units). The main benefit of the Bosch 23 is that it self feeds, so while its pulling an item through by itself one can be getting the next stuff ready. But if its all soft and leafy, and you have no harder bits to pull the soft stuff through - one would be better off with a high speed rotating blade and noisy shredder that you'll have to push most of the greenery through. If you have a decent volume of hard material then the Bosch is an outstanding unit.

heavy duty GX engine.

But I was bitterly disappointed when mine came with a Chinese white GP Honda engine and is only light duty. The shop said this is the only option and Hansa stopped using the better Red engines on these chippers to compete with Chinese imports. Ironically some Chinese imports are now coming with the Honda GX motors.

Another issue is the narrow chute design. My neighbour’s works well because most of the stuff he puts through it is straight. Mine is a a bit more bushy and has to be tediously be broken down into small bits and pushed with a stick. It takes for ever.

Before you buy these chippers, take the above into account. Especially the light duty motor.

Way too much work to do some simple mulching – Overall this is a good mulcher however there are a few things that are irritating. The output chute is just about on the ground and requires frequent… Read more

clearing - every 30seconds or so. Having a rod going through the middle of the chute also increases the chance of blockages. This precludes using the bag as build up is even faster. I use a garden tool to clear the chute and a blower to clean up after mulching. This all makes mulching a much lengthier task.

The mulcher really does not handle wet materials well and is even more likely to clog up. Clearing this out takes quite a bit of pulling apart of the machine requiring the use of multiple tools. The chance of losing nuts, bolts, and washers is quite high.

Having used the machine for 6 hours or so I now expect that I have to sharpen the blades and flails. This also requires quite some disassembly using multiple tools. The blades are fairly small and I expect I will need to buy new ones every couple of years.

I probably would not buy this again as it really requires too much effort beyond just mulching.

included the removal of all housings, belts and motor. I took photos of the dismantled machine and sent them to Hansa for advise on the next step. This step entailed the dismantling of the bearings and drive shaft. Simply there were several nuts and bolts Simply I didn't wish to dismantle parts that did not require dismantling. Hansa did not respond. Reluctantly I contacted Hansa for direction to a preferred dealer. I was directed to Nambour Outdoor Power The pulled down machine was delivered to this entity and several days later I was contacted by Text to collect the machine. I was invoiced $ 595 of which labour was 4.5 hours @ $ 110 per hour = $ 495 This is an excessive amount given that I pulled the balance of the machine apart in half an hour. Nambour Outdoor Power simply had to undo 8 nuts and bolts, a couple of grub screws and replace some small parts. I would be happy to receive a response but given the issues raised have some doubt one will be forth coming. Trev

A great unit! – Minimal assembly required, should be done within the hour. You need to ensure you adjust the chute before assembly of the stand otherwise you'll… Read more

have to undo the bolts and remove what you've just done! Not clear in the instructions. Took way more oil to fill than indicated too! Mine starts first/second time every time. Revs down low, choke fully open...Let it warm up a little, close the choke and increase revs. I put small leafy branches in the top and larger branches in the side feeder. Anything in the top really snatches, so throw in and DO NOT hold onto it to feed. Also, when you stop the mulcher, you MUST ensure there is nothing left in the side feeder or top feeder. Even a small branch will stop the blades/hammers and in turn the belt will jam, but the motor will run. You'll soon have smoke and if you don't stop the unit, it will likely catch on fire (As seen in other comments). I try to have a mixture of wet and dry things to feed as mixing it up prevents clogging and end up giving you a better quality mulch (which I re-use everywhere in the garden). The only thing I find a little frustrating is that I have to constantly manually move the mulch away from the chute to create space and avoid clogging. I think with a better design, you could have had a movable chute to work on mulch distribution. Anyway, overall I'm very pleased with the units abilities.

Pretty good but not perfect – After over 25 years of active service my MTD Model 645 chipper/shredder died. I'll write a review on this later. I bought the Raptor 700 from… Read more

Edisons and it arrived in a box - unassembled. It came with instructions on how to download the manual. Luckily for me neither the downloading nor the assembling was a problem but that would not be true for everyone. It took over an hour to get the thing ready to go. I couldn't believe it started on the first pull which I thought was a good omen for things to come. Wrong. Once the engine was warm and stopped to empty the bag, it was very difficult to start again. I tried every throttle position. It eventually started but it really drained my energy. So-much-so that I left the engine running on slow when emptying the bag. Not ideal (or safe). I have to say that it chipped even large branches very well and effortlessly. All the small stuff thrown in the hopper was voraciously devoured. Almost scary. However, when examining the chipped/mulched product it contained a lot of small branch material not chopped finely enough in my opinion. I had to dig it out and put it through again. Not good. This was never a problem with my previous chipper/shredder (read review). Overall I think the Raptor 700 is worth the money. You could spend a lot more for little better performance. Further, it doesn't take up much room in the shed - and excuse to get more stuff lol.

sets this mulcher apart from the cheap knockoffs. Secondly, because Masport is a NZ company spare parts are easy to obtain for the future. The Loncin motor starts first time every time, and is quite economical to run. The loop handle for positioning the mulcher is very easy to use and a much better design than individual handles on each side because it enables one handed use where necessary. The price is very competitive, and is actually far better value than the cheap copies which are a similar price. The wheels are not pneumatic but solid tyres which is a good thing as the pump up tyres on a previous mulcher copied from this basic design were constantly needing attention. After using this mulcher since April last year I can say it has fully lived up to my expectations. I chose this particular machine because it has a side chute for thicker sticks and branches which also produce kindling and small wood for starting the fire, since we live on a rural property. The Hansa mulcher mulches everything through the one chute which, while it is a very solid long lasting item, equally as good as the Masport, isn't as good for our needs but only in that regard. I was constantly having to repair a cheap copy of this mulcher (which Ive had for ten years until it was obvious its life was over) because of its inferior construction and thought they were all like that, but am pleased to see that this mulcher is in a completely different class.

changed. The price is reasonable compared to 2nd had ones I viewed and new ones of equal power.

I put off buying a petrol mulcher for about 3 years after the previous one (electric) lasted only three uses. The order made on a Thurs night and the machine delivered the next Thurs morning to Brisbane. One blade was missing but BBT quickly sent two replacements!

For about 18 months I had piled branches & sticks high in the backyard. This machine dispatched the whole pile in two sessions. It is a beast of a machine in what it can handle & does everything promised.

On the minus side, at 80kg it is a bit bulky to move around. Also, I much prefer my own protective glasses to the diving style face mask included. My biggest complaint is reserved for the assembly instruction manual. At A5 size it is already hard to read but the diagrams are very small and the labelling must be a very weak size 6 font - some very hard to read and one picture was not quite correct costing me 20 mins to realise the error. I recommend BBT enlarge it to A4 size format.

In conclusions, so happy with the machine (5 stars), not with the instruction booklet. I find it an awesome machine and BBT a trustworthy company.

December 5th 2018 Update: One of the best NZ/Australian wood chipper

I have had this chipper for almost a year now on my small acreage property, and I must say it is one of the best purchases I have ever made, a real pleasure to use. No more wasting time taking valuable tree branches palm fronzs and bamboo to the dump, all get chipped and mulched and put back into the garden, my fruit trees love it.

It will chip branches up to 100-105mm but only in short lengths of 70 to 90cm there's no need to trim the side of anything less in diameter branches are just drawn it into the chipper. Starts first time every time. I Love it.

to sit in the area above the blades, spinning or vibrating until more material is push in from above. Even then, this area gets loaded with leaves, small stems and soft stalks. The operator has to force the material into the chute, as the blades do not draw anything in. The OUTPUT of the shredder clogs easily when soft material is mulched. This means that the operator has to stop the machine and remove the cover to clear the clogged area. If this is not done, the motor will not restart after being turned off, and on again. Shredded material quickly builds up under the cowl at the bottom, meaning that this area too has to be cleared regularly. Stringy material can wrap around the U-shaped blade, making it much less effective. This machine will mulch/shred small branches and large twigs Ok, but as smaller foliage is fed in, the above problems start. This machine is quite frustrating, and slow, to use.

Very solid mulcher but let down by poor design – This mulcher is extremely robust and really well made, so the quality is excellent, and Forestwest have been a good company to deal with in my… Read more

contacts with them. The first thing to understand is that no domestic petrol mulcher with an engine size of around 6.5 hp, that I have ever used can handle a bigger diameter of green timber than about 50 to 60mm, so you can ignore the " capacity measurement". The blades simply wont last if larger wood is attempted as they chip fairly easily. The motor is very easy to start and economical on fuel. The mulcher comes with a special t handle socket to undo the blade bolts, and other tools. The blades are reversible which is a very good feature. The domestic petrol mulchers I have used in the past have been one of three designs, the rotating flail type mulcher with a blade attached to the side of the flails, the rotating disc with blades but no flails, and the rotating drum type where the drum sits horizontally and the blades are fixed parallel with the drum. The Forest west mulcher is this drum design. In my experience, once the blades develop chips in them, which doesn't take long even with mostly green timber, and pieces of wood get past the blade, it then is able to jam the drum. The drum only has about an 8mm or 9mm clearance with the housing that surrounds it. The problem is that there is no easy way to rotate the drum to clear the blockage. This became a real pain, and I had to resort to levering the drum around with a crowbar in a recess of the blade carrier to free the trapped wood. Once this starts to occur, it just jams every couple of minutes which is incredibly frustrating. So, the Forestwest unit is cheap, robust and better built than a lot of the opposition, but sadly let down by its drum to housing clearance and propensity to jam. With a redesigned skeletal type of blade carrier this could be one of the best mulchers on the market, able to compete with that Rolls Royce of mulchers, the Hansa, but until that time...

The broken blade must have lodged itself in the drum causing the drum shaft housing to crack and pretty much destroy the unit. The unit has to be sent back and they did replace it however I will never put anything close to the maximum recommended size of branch through this machine because I didn't when it broke. 3. On the second unit, the exhaust cover has come off through vibration and there is a hole in the top. It actually looks like it may have been a second hand part in this unit because the missing part isn't attached to the bolt still attached to the cover. I actually pulled the exhaust off to make sure there wasn't a loose part inside that would cause damage. 4. The motor itself is good and powerful enough to probably chip up to the maximum 120mm but the quality of the rest I doubt anyone has ever put something that big through. 5.

What's the difference between a chipper and a shredder?

A man in a yard feeding thin branches into a Stihl brand garden shredder

Image credit: Stihl.

A garden shredder processes any raw garden materials, such as lawn, hedge, and tree cuttings. They’re great for managing lighter garden waste, and generally can’t break down larger branches.

A garden chipper reduces wood from branches into small wood chips. Most wood chippers should be able to shred leaves, but if you don’t need a chipping function, then you may be better off buying a shredder, which are are generally cheaper.

While there are plenty of garden shredders that can both chip and shred, there are still many garden shredders that cannot chip larger branches - you’ll have to have a think about what’s growing in your garden and choose a machine that works for you.

What can I do with shredded garden waste?

Before throwing your shredded waste straight into the green bin, consider putting it to use in one or some of the following:

  • Composting: Garden waste can be added to your compost bin to help soak up vegetable peelings and green waste.
  • Worm farms: You can add dry grass clippings to your worm farm to help balance out your food scraps.
  • Mulching: Woody waste can be applied to the surface of soil to preserve soil moisture, improve soil health, and reduce weed growth.
  • Dead hedge: You can create a dead hedge by pushing 2 parallel lines of stakes into the earth and throwing your waste - including unprocessed heavier timbers and shredded waste - into the space between them. This will slowly rot down over time, letting you regularly pile clippings on top.
  • Bonfires: Some thin, dry stems burn well in bonfires, but because fires create pollution and should only be made in accordance with government guidelines, this is usually only recommended for the odd cleanup, party or camping trip, and not as a regular way to use your garden waste.

Types of garden shredders

Choosing a power source

You should choose a power source that’s convenient for you and fit for purpose - garden shredders can be petrol-powered, electric, and on occasion, battery-operated.

Petrol garden shredders

Petrol garden shredders are more powerful than electric shredders, making them suitable for tackling tougher yard jobs.

Pros
Suited to more heavy duty jobs, as they can usually shred thicker branches with a diameter of up to 6cm.
Are more effective at shredding a variety of garden material.
Can be used in remote areas or anywhere in your yard, as they don’t need to be connected to an electrical socket.
Cons
Generally more expensive than electric mulchers.
Often heavier than other garden shredders.
Usually require more maintenance than electric models.

Electric garden shredders

Electric garden shredders aren’t as heavy-duty as petrol shredders, but for small to medium yards, they’re often right for the job.

Pros
Usually easier to use than petrol mulchers, as they just need to be plugged in.
More affordable than petrol shredders.
Generally lightweight.
Quieter than petrol models.
Cons
Need an extension cord suited to outdoor use in order to use your machine.
Don’t offer as much cutting power as petrol garden mulchers.
Can’t be used in wet conditions.

You can also find battery-powered garden shredders - these generally aren’t as heavy duty as petrol or electric shredders, but they can be useful for people with light gardening work.

Impact shredders versus crushing shredders

Impact shredders

Impact shredders have a sharp, spinning blade that slices garden debris.

Pros
Quick.
Usually more lightweight than a crushing shredder.
More effective on leaves and freshly cut ‘green’ debris.
Less likely to become jammed.
Usually cheaper.
Cons
Noisy.
Blades will eventually lose their sharpness and require maintenance or replacement.

Crushing shredders

Crushing shredders have a textured roller within the machine that crushes the garden material into small pieces.

Pros
Quieter.
More suitable for drier, woody garden material.
Crushed material composts more rapidly.
Cons
Pricier.
Can clog up if garden material is too green or wet.
Often less portable, as the top is often heavier.

How do I choose a garden shredder?

Maximum branch thickness

Garden shredders have a maximum branch thickness that they can work with, so choose a shredder that has the brawn to do your toughest job.

A machine capable of cutting thicker material is useful when shredding branches that aren’t completely straight, and can save you having to precut and feed branches into the hopper one at a time. However, don’t get carried away with buying the most heavy-duty unit you can find if your yard doesn’t call for that level of power.

Safety

Garden shredders can be dangerous if they’re used incorrectly, so ensure that you’re closely following the product manual when using it. You’ll need to wear eye and ear protection, gloves, sturdy shoes, and long pants, to protect yourself from debris shooting out of the machine.

Kids and pets should be kept well away from a garden shredder, and if you need to fix a jam in the machine, make sure the unit is switched off and unplugged before you unblock it.

Ease of use

Check the machine’s size and weight. Does it fit into your intended storage space? How easy is it to lift and manoeuvre? Does it have wheels for you to easily transport it?

If you’re going to be shredding close to where you’re storing the shredder, then this may not be as important. However, if you expect to have to carry it over some distance or need to take it over rough terrain, then you may want to consider a more lightweight model.

The size of the hopper - the chute that you feed the debris into - should ideally have a large opening that makes it easier to guide material through and reduces the risk of clogs.

You should also see how simple it is to remove, adjust, and replace the blades. Some machines also take reversible blades - these can be turned around, essentially doubling how much use you can get out of them before they need sharpening or replacing.

Also check in store whether you can easily access and use the controls, particularly when wearing gloves.

Features

There are a few extra features to look out for that can make using your machine easier.

  • Reverse function: This feature is found in most garden variety shredders - it throws debris back out of the shredder in the event of a jam.
  • Collection bag: A collection bag collects the processed material as it exits the shredder - if one isn’t included with your machine, then you can use a large plastic tub or durable garbage bag.
  • Plunger: This is usually a small stick or paddle with a handle that is used to push the organic material into the machine, helping you keep your fingers at a safe distance from the shredding blade. You can use a thick stick if your shredder doesn’t come with one.

Noise level

If your neighbours live in close proximity to you, then you’ll likely have to consider the noise level of your garden equipment.

Garden power tools are generally quite noisy, and garden shredders usually produce anything from 70 to 115 decibels of noise - crushing shredders will be on the lower end of this spectrum, while impact shredders will be louder.

Ensure you check the manual of any product you’re thinking of buying to check how much noise you can expect from it, so you can nip any potential neighbourly disputes in the bud.

Mulching ratio

To compare performance across machines, look out for mulching ratios - this shows how efficient a shredder is at reducing waste. For example, a 10:1 mulching ratio means that for every 10 bags of garden material you process, you’ll get 1 bag of shredded debris. The higher the ratio, the more you can expect your organic waste to reduce in volume.

Is it worth buying a garden shredder?

A garden shredder can cost anywhere from $150 to over $3000 - electric shredders will likely cost up to $800, while petrol-powered models often start at around $700 to $800. You can usually expect to be covered by a warranty from 1 to 5 years.

If you find yourself constantly pruning the trees, hedges, and bushes in your garden, and you find that you’re usually left with more green waste than you know what to do with, then chances are a garden shredder will be a useful piece of equipment for you to have.
