    Blade on my ambrogio 250s+ bent and cut through the plastic guard. Happened before and just jammed -I straightened the blade and it worked fine for a few weeks but this time cut through two sections so I think I need a new blade and guard but I tempted to just straighten the blade again and leave off the guard.

    Has anyone just left the guard off?

    Same happened to me within 10minutes of its maiden cut (Grass too long + cut height set too low). Happened a few times since. Took the guard off and cutting the last few weeks without it. Don't notice any issues. Think its main function is to protect blade from stones or other foreign objects. Not a great design though.

    Have the exact same model and same problem. Agree with people here it’s a terrible design. My solution was to buy spare blade guards and a new blade. I’ve kept the guard on for now as I have 2 smallies I don’t trust not to poking at the mower.

    I found the problem was the mower hadn’t got on top of the lawn yet. So I patched up my original guard (gorilla duct tape worked great) and straightened my blade. Thoroughly cleaned the deck area and coated it head to toe in WD40( it stops the grass cutting’s sticking) and sent him back to work. I checked him every evening for a week cleaning the deck and guard with a bottle brush. After 2 weeks once Luigi got on top of the cutting there was no need to check every evening so now I do it at the weekend or just after rain. When I drop the cutting height I’ll check every evening for a couple of days just be sure.

    So in conclusion the new blade and spare guard were not needed and are now backup spares. All I needed was a roll of duct tape and 2 pound shop bottle brushes and a nightly check and clean for a week.

    A few weeks ago, the front wheel came off my husky 450x :(
    Turned out the lockwasher within had deteriorated and snapped. I checked the other wheel and it too needs changing. Luckily I have one handy, but they do not seem easy got locally. It's diy territory to replace.

    The front wheel tyres are wearable and should be replaced (diy) every so often if you notice wear, as like mine the rubber wore and left a gap to the wheel plastic housing. That left muck squeeze in which caused the lockwasher demise over time. 3 years in my mowers case.

    What have I learned: pay more attention to the tyres, I haven't seen it mentioned as a potential issue in the thread.

    Maybe for those who is or for an annual dealer service are spared this.

    Also, when I'm ordering bits and bobs, get a stock of those wearable washers, bearings, screws, tyres. Those bits cost pennies but are priceless when stuck. I will check in with my local dealers to try get a few more. In the past I got from UK GPL but delivery is pricey.

    Happy mowing.

    Very similar on 430x a couple of weeks ago. 3 years old too. Broke a bearing on one of the front wheels so it fell off. Like you said only a couple of euro for the part but was going to have to wait a month or so for local dealer to get one so ordered on line. Since I was caught to pay for shipping I replaced all 4 bearings on the 2 front wheels

    my Husquvarna 420 has been acting up ... cutting for 15 mins and suddenly stopping saying 'no loop signal' .. .the loop is fine and the dock has a green light.

    I saw mention online of people saying to 'create a new loop' ... which is in the installation menu .. took a few attempts to get it to work .. but 24 hours on .. fingers crossed .. it's cutting away.

    Why would it suddenly have issues with a loop that is working for the last 4 years !

    Here's a question I've been wondering about...

    If you were inclined to spray some of the grass that the mower touches without cutting, would you pause the cutting program for a week (or until it rains - whichever is less) so that the mower doesn't contaminate anywhere else?

    Systemic weedkillers work by the weed itself absorbing water in the usual way as it grows - except this time you've added glyphosate or whatever other active ingredient that then attacks the weeds structure to destroy it.

    This is why the best time to spray is in sunny, dry weather with a lot of active growth as the plant soaks it all up like a sponge.

    I'd say the risk of your mower spreading enough weed killer beyond the target area to other places to cause any noticeable damage is minimal.

    That said though, it's probably not unreasonable to suggest turning off the mower for a day or two after spraying or perhaps until the lawn has had a couple of showers of rain.

    Kind of what I was thinking.

    I'd still be interested if others maybe don't do that and experience no issue.

    Got my Ambrogio L350i out taming the field, eventually! Although the grass is a bit higher than I would have liked to start it, it's making great progress. The actual field still needs to be rolled as its full of bumps, dips and tractor tyre marks, but C3-PMOW doesn't seem to mind much.

    I raised a question to worx about the way the mower leaves the base.

    I had noticed that it ALWAYS leaves at an angle (reverses a few cm then turns about 45deg left) and never follows the wire out.
    This means there is a patch just after the base that "never" gets mowed as the random nature makes it so unlikely.

    Worx response was to set up zones. Which makes sense as it calculates the start of a zone by the distance along the wire.
    I haven't tried it yet but thought it might help others to post.

    I have a pretty strange request and kind of embarrassing request, but would anyone be willing to look over a script I'm writing for a video on robot lawn mowers?

    Would appreciate the input regardless of your knowledge level:
    • People who know what their talking about might see things I messed up
    • And people who are even just looking at robot mowers it would be great to see if there are gaps or questions that you still have

    I'll be hopefully adding footage illustrating most of the talking points when I'm making the video and the script may need to be tightened up quite a bit, but I just want to check if the content is what people would expect. If there are advantages/disadvantages I've missed please let me know!


    The installation tips section is not finished , but I've added the main bullet points I want to cover. This wont be a detailed installation guide, I would expect maybe 10-15 seconds per point roughly

    I don't normally make this style of a video so it's new ground for me.

    Script is here: https://docs.google.com/document/d/1M6iNpn5UfBQeap-p4Bah7kosZmA3uy3iK0hnP0mLKDg/edit?usp=sharing

    Thanks!

    Decent script. Looking forward to the video!

    Some comments..

    Guide wires are used for more than accessing remote parts of the lawn. They are also used to help the mower get back to the docking station quickly. With a large lawn you could be looking at the mower travelling 0.5km's to get back to the docking station via the boundary wire.... thats alot of travelling if the docking station is only 20m's away!

    They are also necessary if you have long narrow strips. The chances a robot will get through the strip without a guide wire are slim so guide wires are "mandatory" in some cases so it is something that prospective buyers should seriously look out for as some robots dont have any, some have 1, some have 2 or 3. Figure out if you need a guide wire for your layout and then buy appropriately.


    One disadvantage that I have found is that if the mower breaks down and it has to go to a service center you could be without the mower for a week or two during the peak growing season and so the lawn looks terrible for a while when you put it back out. The grass could even get too strong for it and you have to borrow a ride-on.

    Thank you! Especially appreciate the guide wire feedback, will help round out the information. Yeah if it broke I think I'd cry :(

    Eugh, really sorry! I was a mod in a former life and mods have bigger inboxes , so im left with 2.5K PMs and a limit of 500 and I can only delete 50 at a time.

    They fixed for me before so hopefully they can again. Will let you know.

    Hi all, sorry if this is an annoying post but rather than wading through 3000+ posts I was wondering if anyone had any thoughts on Husqvarna Automower 305?

    My garden is about 350 sqm. with quite undulating terrain, some gentle slopes and some narrow bits (1 metre wide at the most extreme narrow "corridor" between hedge and house. Looking for a good all-rounder that will be built to last.

    My first step would be to measure the slopes to make sure they don't exceed the mower's specification.

    I'm on the 2nd from the highest for worx.
    But I am trying to let it get on top of the moss and weeds this season.
    Over time I plan on lowering it

    How does that work? You let the grass grow long enough that it hangs down above the moss and weeds blocking the sunlight?

    Tried radio text umpteen times with various radios and no joy. V frustrating.

    Any tips please ?!

    Poss anyone with a proper detector than can be borrowed ? West dublin.

    I'm sure this topic covered before but could not find.

    Thanks.

    Tbh, I'm not sure it will work yet!
    I'm also hoping that the thatch will thin out.

    I have come up with that plan based on a bunch of different bits of info and ideas.
    Thankfully the head height doesn't make them lawn unusable at all so I'm happy to see how it plays out.

    I can see that the height might need to come down to get on top of the weeds but I want the moss under control first.

    Where do you order your spare parts from? I've a Husk 105 in to its 6th year and to me it seems to be falling apart. I'm advising someone else on getting a mower and I am a bit concerned that they are not as robust as I would hope.

    Local dealers (poor, slow to order), online GPL UK (delivery pricey mostly but they have extensive parts and importantly diagrams but a week delivery), Atkins (cork, fast if stuck, got a wheel motor in 2 days), Robert kee, Amazon, eBay. Whatever works

    Irish prices are higher too, surprise.
    There are German sites too that I'll use next for batch of washers, tyres, bits and bobs. Prices are much better, but
    As you see, I have zero loyalty

    I've a Gardena Sileno Life mower for the last 12 months and it stopped charging a few days ago due to corrosion to the charger base, hard to believe this is happening already but there is no decent sealing around the electrics compartments, just snap together parts which are really no good in this climate.

    It doesn't help that I have the charger base under a hedge but I made a timber box for it since January so it may protect it a bit more.

    Does anyone have problems with woodlice & slugs getting in for the warmth of the electrics?

    I bought a good few small bits for 439x from dutch site...wolfswinkel. Only one I found that had everything I needed in stock. Slow enough shipping through normal post. Parts were same price or cheaper from Atkins just weren’t in stock. Couldn’t afford to wait for them with no machine running with the growth rate at the moment

    You dont need to program it for that. If there is a gate in the way and its closed it will bump against it and turn around and head off in another direction.

    What you dont want is it getting through the gate, someone closing the gate and then it not being able to get home. So, it depends on how that gate is used.

    NOTE: You need to be able to run boundary and guide wires along the ground through that opening and it needs to be wide enough for it, so if you are talking about a narrow gate it wont work.

    Sorry about hijacking this, has anyone seen any kind of automatic door/hatch for a hole in a fence between 2 garden sections, that the mower can trigger to open/close as needed?
    I have seen a flap by a automower rental franchise that their mowers can push through without the bump stopping it, but I'd prefer some more solid that can be closed to keep a toddler in, and also not have a very visible gap in the fence.
    I could go down the diy route with sensors and a motorised hatch but, yeah, would prefer a reliable solution.

    I had loads of moss in my lawn, now I have none except at the very edge where mower does not cut, I think its the constant cutting/mulching/feeding of the lawn that keeps it away. I cut mine at number 5/6 on the Husky scale, shortish, without being cut too tight.

    But I've now got it back on the rest to deal with the aftermath of the 10 glorious grass growing days we've had.
