Ryobi Crushing Shredder RSH2445S Questions & Answers

Sorry, but no I haven't tried our Ryobi on that type of bark yet. Must do so as we have a few trees with ribbon type bark. If I remember to do so, I'll let you know here as to my success or otherwise.

I am using it to shred tea tree and pittosterum tree branches at the moment. You will need to adjust the size blade handle to set the blade to close (see instruction manual) and you will have no issues.The tea tree has stringy bark and the shredder is handling them with no drama. It mulches / crushes both wet and dry. Better shredding results from slightly drier branches and it does not like so many leaves so try and throw a few sticks in between to help it not get clogged up. The auto feed is amazing I just place a branch in and as long as it starts to feed down the chute I can walk away and grab the next branch.

I think the problem is that there is too much gum in the stuff you are feeding into it. They work better with dry material. If we have smaller shrub pruning to run through it, we leave them for a few days (as recommended by Ryobi) to let them dry a bit and then we run them through the shredder. We also put some older, drier branches through it as they help to clean the cutters. It's good to finish off with such dry matter as well. Hope this helps you.

Hi there, I found I had the similar problem with excess leaf build up but found by feeding through dry stick only branches the shredder unclogged itself. I feel the gum is the problem here being way to much and too sticky. Perhaps spraying WD40 into the cutter may help here - who knows could not hurt. Maybe toss in a few different branches every few to ease the gum. I have used my shredder for both wet (new) and dry branches. It shreds the dry branches into finer more manageable mulch and leaves the wet branches in long cut ribbons in places. So I mix it up and the shredder works amazingly better. I use mine for branches up to 50 mm thick. If it fits in the hopper then it gets shredded and we are talking roof height branches. The auto feed takes them with no hassles. I always make sure the cutters are empty before storing for the next use though to avoid clogging at a later stage.

Thanks folks, I’m thinking the same now. That’ll I’ll need to leave the material for a few days and then be sure to mix the woody stuff with the leaf material.

Not really, as the mulcher delivers coarse mulch. Much better for solid branches

Not sure what's happening. As never experienced this fault. I suggest you take it back for a refund or exchange if still under warranty.

How did you go with this problem? I’ve got the same issue now & im not happy! I’ve looked for new blades can’t find I’ve taken the blades out I’m thinking I’m going to sharpen them by hand I’m going into Bunnings to ask in the tool shop about this problem.

I was having the same problem but tighten up the blades by turning clockwise and now it working great. Don’t think I can turn it anymore now.

I personally don’t think so; for one thing bamboo is usually wider diameter than the shredder is built for but also bamboo tends to splinter, so I think the results could be a hazard around the yard.

Thanks Jehaz, I’ll let you know if I go ahead and write up on it.

Even if the bamboo is small enough it doesnt really like processing it when green. I tend to find it passes the stem and part cuts it leaving me with the need to chop it off when I have to empty the basket. Personally I wish I had gone for more of a drop model straight into the bin if there was such a thing.

I’ve never seen this but offer just a thought. Is the rotating drum which carries the blades jammed? It seems to me that assuming the bin is correctly positioned and the slide closed properly, then all should work. Reversing of the motor is usually a sign that something is jamming, usually because too big a piece of wood has been fed into the hopper, the blades cannot pull the material through and are trying to “self clear” by reversing the movement. Maybe something like a length of material such as binder twine has got fed along with the wood. I just had to do a major clean of the cutting assembly and was surprised how much was stuck, even with the blades still rotating.

thanks have cleaned it all out several times but will look at drum

Haven't had a problem "as yet" you haven't overloaded filled bin ? I when using stop shredder pull down what's shredding Just a thought this if isn't being done may cause your problem

It will cope with the dead plant, roots and all but I wouldn't want to push much dirt through it. If you knock most of the dirt off the root ball first you should be fine. Also keep in mind that the opening at the top is 35mm wide so that is also going to be a limiting factor in your case.

Not sure - sorry. I would check with Bunnings or call up Ryobi.

I have never used it just for leaves. I have used it to do trimmings of murayas, hibiscus, etc. I doubt that would work only on leaves. It does do palm fronds.

No. It’s designed to crunch twigs branches (up to about 35mm in diameter). The output is kind of like wood chips. If you put leaves in they just come out unchanged.

Is this any good to shred cardboard for mulching?

How did the replacement go?

Not sure but probably not. Small pieces of wood do not go through. The branches need to be held vertically to go through the blades which operate vertically. This is for the cruncher. I think the shredder would not be any good either. The blades with the shredder operate horizontally so like the blades of a mower.
