Has anyone had issues with their Ryobi Mower rattling very badly. Iv used the mower once and have noticed that the front left wheel axle is held on with nut and bolt but is loose and no matter how much I turn the nut or bolt it won't tighten right up leaving the axle to move and rattle? Anyone else had issues with this?
Just purchased a ryobi 140 lawn mower primed and started but cuts out will not keep running. Any ideas?
Tried to start my ryobi for first time this season not working notice the fuel was turned on all winter could this be the problem there is fuel and oil in it
Hi AnneO - I don't have a lot of mechanical expertice, but hopefully this might be of some assistance. I think the fuel is compression-fed, not gravity-fed, so I don't think leaving the fuel switch on all winter would cause an issue (that said, I could be wrong). If it was me, I would try draining the fuel, draining the oil and replacing them with fresh fluids. Also check and clean the air filter. Finally, clean and/or replace the sparkplug. Do you regularly wash the cutting deck via the hose attachment?Try giving that a go. There maybe something blocking the rotor from turning. Hope this helps and best of luck!
Another thing that a lot of people don't realise is that petrol becomes stale over time and won't start an engine. This is because it loses the volatile components to evaporation if there's any way they can escape to the outside, so quite often just a change to fresh fuel will fix the problem
My usual checklist for this would be (mostly covered above) * is fuel tap on? * is fuel line blocked (including inside tank) (which can be water-in-fuel) * does spark-plug wire shake loose or change grip when hot? Other experience direct - it's relatively easy to spill engine oil on the air-filter with a bit of injudicious handling and side-tilting. Hope this helps. I've been caught out with the fuel tap turned off by third parties more than once.
Have a brand new 190cc. 1st time using it but runs for a short while then chokes and eventually cuts out... there was a smell of burning.as soon as it cools down starts no problem but problem reoccures time and time again. I did overfuel it initially.... any suggestions or help???
Sorry but I can't offer much help with this question. The Subaru motor in my Ryobi mower starts easily and runs well. The problem I have is with the mower itself as long or damp grass builds up underneath it to the point that it has to be cleaned out or it will stall - i.e. the mower doesn't throw the grass out as mowers normally do. The Subaru motor goes really well and it is the Ryobi component of the mower that is badly designed. Perhaps you could either go back to your retailer or contact the Ryobi company itself for help?
Thank you Stella123. I have contacted the retailer and they suggested I return as the purchase is still within the 7day return policy.
Hate to ask a dumb question but did you put oil in the engine before you used it? They are sold dry, with no engine oil so you need to fill the sump before using them. That's all I can think of. But if it's not that you need to take it back to the dealer if it's brand new. There's something not right there
just bought a 175cc Ryobi, works fine but lot of cut grass is left without collecting in the catcher. This is doing my head in. Is there a setting I need to check? Catcher does fill but why does so much grass not collect. thanks
Gary, never actually encountered this problem with my mower, only ever cut very dry grass with it, probably have the same problem if it were even slightly wet as there seems to be a number of users having this issue. Don't really know how to overcome it, sorry mate.
Sorry Gary but I can't really help you with this one. I have a different model Ryobi mower (194 cc) and don't use a catcher with it due to the problems with the mower body blocking up with cut grass, as per my previous post. But I am aware of your situation as I have another brand of mower which is also reluctant to collect the cut grass in the catcher. I have been given various theories about the cause of this, but perhaps if you contact the manufacturer they may be able to offer a more viable solution to your problem than what they offered me for mine.
Bought the 175cc the other day. Came with 2 blades already fitted. I noticed it has holes to add an extra 2 blades. Is it worth having 4 blades on it? With 2 blades it seems to leave cut grass trails on the ground and the catcher chute always clogged up (it rained the previous night but the grass was dry.) So should I use 4 blades and will it work with 4 blades installed?
Hi Liam, the mower i bought has 4 blades fitted and obviously a larger motor than the one you have, 175cc versus 190cc hence the extra blades i would assume, don't see why you can't add another 2 to yours considering it would appear you have the same blade disc as the 190cc, only way to find out i guess is to give it a try and see how you go, i'm sure it would only improve the cutting capability, hope this is helpful albeit somewhat vague.
Liam, I endorse Jimbo's suggestion - give it a try. I had 4 blades on a 140cc Masport, no probs. I don't recall chute-blocking being an issue with the Ryobi (it is with the Hondas) but you could see if you can a) get blades with a little more 'lift' - look at the shape, they're a crude propeller - and b) try running on different engine speeds, probably faster. Also - check the mulching function, which can duplicate a chute-blocking result.
Hi I've only had the mower a short time, I have used it perhaps 3 times. On my last two attempts it has reluctantly started, but then seems to throttle slow to fast and then slow to fast again without me touching the throttle. It then eventually stops. It's practically brand new so wasn't expecting problems like this yet... any advice?
Make sure the fuel tap is turned on. Also see replies to other questions.
Sounds like the hunting issue other have complained about supposedly caused by dust in a certain spot.
I'll be investigating this on my mower this weekend.
When my mower did something like that it ended up being the air filter had dust and oil residue in it, so it was struggling for air. New air filter fixed the problem. The filter can become clogged with oil if you mow sideways on a steep block. Also, if you have it shaking around on the trailer without turning the fuel tap off can facilitate oil making its way into the air filter.
Hi there my ryobi rlm46173sme will start but won't run continuously any ideas many thanks
General Mower advice:
Fuel + Air + Spark = running motor
Fuel - check the fuel tap, make sure it's turned on and the tank is full of good petrol (it's weird my mower will start and run for a little while even if the fuel switch is turned off!).
Air - open and remove the air filter temporarily (don't mow with it like this!) - if it's really clogged it could be flooding the engine.
Spark - try a new spark plug - I've have some that don't work/work intermittently when hot... (If you're game leave plug out & earthed and look for spark - only if you know what your doing - be safe!!!)
Problems like this are usually(not always) fuel related. After this you're getting into pull apart territory (or taking it to someone).
P.S. After reading Peters reply below about the hunting - it could also be related to this. I agree with Peter - this mower seems to create a larger than normal air vortex action which while good for moving the grass into the catcher also creates a massive amount of dust which seems to coat the engine on every mow and requires constant cleaning.
I had same problem with same mower from new.I found video solution on U Tube.Undo fuel bowl on carburetor [middle nut] and clean.I had crystals in mine looked like sugar [spoonfull] and rust,I cleaned with wd40,I put petroleum jelly on O ring seal.It's a brand new lawnmower again.Good luck I hope it helps. Jim S.
My first one of these lasted about three months before the engine started hunting then when starting backfired and would not start. Bunnings replaced it no worries and now the second one is starting to hunt. Any ideas?
Sorry I can't help you. I won't buy another - I'll stick with Mountfield with a Briggs and Stratton engine
This is not the proper way of evaluating an engineering problem it requires visual evaluation but because I have one I just may fluke your problem. The Subaru 4 stroke engine is very well made but the Ryobi chassis is poorly designed allowing exceptionally high amounts of dust to cover the top surface of the mower's chassis. This is right where the filter intake is to the carburetor and it becomes saturated with microscopic dust which causes the engine to run excessively rich and the indication to the starting of this problem is the engine begins to hunt just the same as if the choke was fully on when the engine is hot. I mentioned earlier about how to fix this problem but this requires an engineer who can set the chassis height off the ground successfully at the correct height so that the engine is then packed up to take the blades further up into the curvature of the mower frame. Your only alternative is what I had to do until I changed the body height and that is you have to blow the filter out with compressed air every time after you use the mower.
Not sure if anyone is still following this thread but I have a question I hope someone can help with. My father-in-law gave us one of these Ryobis as a house warming gift, assembled and ready for oil and petrol. Before putting the fluids in I flipped it onto its side to check the blades and was initially surprised to see the folded in against the central disk and able to move around. The answers to comments above addressed those concerns. I turned it back over, put the oil and petrol in and pulled the cord to get it started. Next thing there is a terrible clattering sound as the tips blades are clanging off the inside of the chassis as the centrifugal force throws them out perpendicular from the disk. It seems they can't soon without hitting off the insides.
Has anyone encountered this before or have any advice?
How do you start this lawn mower?
The same way as normal for most mowers. :) Out of the box I put oil in, put fuel in, turned the fuel tap to open, put the throttle down to open, pressed the fuel primer 3 times (making sure the breather hole in the primer button was completely covered), pulled the rip cord and the mower started. :) Hope this helps! :)
I've had my mower for 2 years, about 12 months ago the mower stopped, no spark, was told by the repair agent it was the coil he said a new one was fitted, the mower went fine until 4 weeks ago same thing advised it was the coil again and a new one was fitted, picked it up yesterday and still no spark.
Assuming that it now has had 3 coils, what else could cause no spark?
Sorry Coaster,I run to mower basics at max. and never intended to present as an expert .
I'm sure it's more complex than this but spark plugs work better if removed and sanded with some glass paper or a small file to get rid of carbonisation so contact works better (shiny contact points are important for the spark transfer).Or obviously a new one is an option . I used to clean my spark plugs with petrol but have heard since this may not be sound practice from a safety perspective, In truth you need to seek a wiser head than mine on this subject,- It sounds more complex than my solutions.
I am a user/ commenter and would not get a job anywhere at any time as a mechanic. Cybersapce is a big place .Try some Googling ? Otherwise mate I am no help. Best of luck with what sounds like a Bi#*ch of a problem.
Hi, just bought 175cc ryobi and the blades are not tightened, I can move them rather easily and don't think this can be normal and I tried tightening them, but to no avail, any thoughts?
Also the motor smoked a lot when I started it.but assume this is part of running it in?
The blades on any lawn mower have to swing as a protection if you hit any solid object. As long as the disc is tight and not turning on the shaft.
Simo You would expect to be able to move the blades with a moderate amount of effort with the fingers . They are not meant to be rigid. If they move with a bit of pressure there is no real issue. If they swing freely under very low pressure they may well need tightening . As for the smoke this is very typical and nothing to be alarmed at.It will decrease quiet quickly once you are underway. It is a 4 stroke engine so hopefully you didn't make a blue by putting in 2 stroke fuel ? I assume you haven't but if you had a 2 stroke mower before its always possible you grabbed the old petrol can (?) This wouldn't wreck the engine if only done once -don't repeat it if you did ),, but it could lead to a smokey result.
wanting to know if it's worth the price have thick grass and slopey ground but small area don't really want to spend 470 as there are alot of cheaper variants but will if worth it.
Look I think it's the best mower I've ever had, I have a fairly small block with sloping ground and I hate mowing. This one makes it easy and (just) bearable in Rockhampton heat.
I can't tell you to buy it, everyone has to make their own call but I reckon I'll still have this one for years - which is why I spent a bit more.
Sorry for not responding sooner. I have had a few health issues that have stopped me from following up.
I live in a Sydney's far north and while not comparable to Rocky I do live on a north facing sloping block with the main grass type being the virulent Kikuyu which I'm sure you know goes "berko" at this time of year - very thick and long in a short period.
The mower has been used by my son a few days back and today by my wife. Both report good things. They support my contention that the motor is strong, fast & quiet. Both say that the problem with loading & unloading the catcher is no issue and was a “me problem” . I was mowing under sufferance (in pain ) when I did the job and may not have been in the most sound frames of mind. This mower has started first time every time for everyone including my wife who has complained in the past that she can't start the mowers we have had because they need more strength than she has. Cost comparison in your case ? Pretty subjective. My block is pretty big and it takes 1'40" in summer to complete the job with no breaks. I previously had a top of the range Victa which I paid nearly $800 for and I consider it largely a dud so this would colour my views about this one. Without wishing to sound un-Australian my experience with Victas has been less than good - in the last 30 years I have had 3 and each one has been rubbish when compared to the Japanese made counterparts I have used (The Honda one I had nearly deserved to be next to me in bed it was that good). But the Jap. ones are more expensive . I would say go cheaper if the job normally takes less than 45 mins. If more, spend the money and get rid of the angst. While obviously early days this engine is superior to those I have seen and (IMO) would seem to justify the price tag,
Today we purchased a Ryobi RLM4619 SMBS lawn mower. We are having trouble tightening the handle at the base near the wheels. Could anyone please let us know how to do it as the hand moves forward if we push too hard? Any feedback would be appreciated. Ron and Lynn
Hi, I have bought this lawn mower last weekend after lots of researching. Starts first time. Very quiet compared to other mowers of neighbors. Only problem so far is why does the little grass comes out from the little holes on the catcher (in green color)? Can anyone confirm if I'm missing something os is this normal? Grass catcher is bit annoying to put on. I found the spring has started getting lose.
Hi, pdave cannot answer your question about colour I thought all grass was green its the nature of it. I took my mower back as soon as possible, motor good but mower is not balanced properly, you cannot mow uphill or on soft lawn, the front just digs in. The only way I could mow my front lawn was pull it backwards, not satisfactory
Just wandering my air fliter has cracked sow were can i buy an new one number RLM4619SME if any one can help me on here with
kind regards Garry Read
I've had my Ryobi mower for 6 months or so, and it was performing fine, but the last couple of mows it's been really hard to start, and it seems to lack power when it does eventually get going. Could this be a dirty spark plug perhaps?
The catch bag doesn't seem to be ideally suited for the mower. Why does it have the side hooks with nowhere on the mower to hook onto? has anyone else found this catch bag awkward to place?
How much does it cost and Bunnings don't have it listed on their web site
Bunnings - the fast buck merchants. Don't think they handle these now - seem to have done a major deal with Victa or some other mower mob.
Don't buy from Bunnings because you can never rely on them to continue product or to support stuff - they always end up with obscure agents who never seem to know what they are doing.
For service and continuity stay with your local mower shops - they are competitive!
