    Definitely not an architect, just handy with the old computers. Have these plans made out for a couple of reasons so it's handy to post to various places as I need to.

    I haven't actually purchased any goals yet but most of them have the nets wrapped around the bottom post so that's why I was a bit worried about it. I could see about getting ones that have the nets inside the post 🤔

    To be prepared, I went and got the Worx Landroid L2000 and I don't think that has guide wire capabilities, just boundary wire, so hopefully it'll still make its way in ok.

    Good tip about the 90 angles!

    Thanks, just wondering which you buy? the default/longlife or extreme safety?



  • Registered Users Posts: 153 ✭✭ SocialSpud


    Think I just found the solution 😁

    These may have a similar problem, if the mower doesn't bounce off the bottom of the goals (which it looks like it wouldn't it has a diameter of 6cm, which on paper looks ok but im not sure) it could possible drive through the net

    Your options probably are

    Physical barrier, put something like piece of timber around the bottom of goals so the mower will bounce of it. Not sure this will work great from both the inside and outside though. I do something similar on the legs of my trampoline and it works perfectly, but not sure if it will work well with the goals. Not my picture but ive done the same things as this.



    Boundary barrier, if the goals are going to be in a fixed location, you could make a boundary island for each of them like you would with a flower bed.


    Off limits add-on, is a less "permanent" way of achieving this , still requires it to be pegged down though. it is probably easier to remove/reverse if you wanted to


    Personally I would probably go with the boundary wire, you could always remove it if you wanted to with a couple of those patch connectors.

    Found this online, sold as a potential free add-on if you buy from agrieuro.co.uk. I can't find anywhere else online that sell it, anyone seen something similar to help install the wire?

    Hi All

    New on here so not sure how this works or if I'm posting in the right place. I've a husqvarna 430x that is acting strange lately. There are two guide wires. One is not showing up at all on the sensors but I cant find a cut in it. The other shows up sometimes and then other times it doesn't show up at all. Mower tends to stay on one side too long and I need move it to the other side. Switch trips at fuse box at night while mower is idle. And I know the mower is causing this because if I try to plug it in immediately it will trip again. Then when I get it going again it will most likely pick one side to keep mowing until I physically move it.

    Any help much appreciated.

    Probably a fault in the docking station.

    Trying taking a short length of guide wire and putting it across the two terminals for the failing guide wire and see if the guide wire shows up. If not, then its clearly not your guide wire at fault but the docking station itself... they have been known to fail.


    Switch trips at fuse box at night while mower is idle.

    That's bad. That will either cause the docking station to eventually fail with all the reboots or it is a symptom that the docking station has an electrical fault that is causing it to trip.


    You need to send the docking station to a dealer I'd say.... probably needs a new board...~ €180ish



  • Registered Users Posts: 4 Husq430x


    Cheers for your help guys

    Just thought of something today. The switch trips after heavy rain and I have the transformer in a plastic box but a drop of water was getting in. So that most likely explains that side of it! And I'd imagine this in turn would put pressure on the docking station and cause it to fail?? So Kcross I take each wire off both terminals on one side and get a short piece of wire. Cross the terminals and if I get a flashing blue light then the docking station is faulty?

    The idea is to rule out your existing boundary and guide wires.

    So, you take a new piece of guide wire and make up a "fake" tiny lawn effectively, by disconnecting all your existing connectors and only using the new guide wire (which will only be a few feet/metres) long and you can cut in some guide wire to it as well to simulate real guide wires..... connect that back up to the docking station and if you don't get a solid green light and 2 guide wires showing up you know it is not your real boundary/guide that's at fault.


    Its just a test to rule out a wire break(or bad connection), it won't fix your problem!


    Do you get a solid green light on the docking station right now? Even when its not showing the guide wires?



  • Registered Users Posts: 839 ✭✭✭ poker--addict


    I like the open mower technology info linked

    I’m surprised mowers are still reliant on boundary wires. Any advancement imminent? Drop and mow can’t be that difficult?



  • Registered Users Posts: 4 Husq430x


    Cheers Kcross

    I'll try this. Yeah I'm getting a solid green. I did the guide wire test on Guide 1 and get a solid green. Did it for Guide 2 and get the flashing blue light.

    So I suspect that side of the station is faulty. I did the find guide wire test with AM radio and it was ok until I got to 10 metres from station when signal was lost. So I gently dug up the wire but found no break. At the minute the phone App is saying the mower is leaving the station (99% charge) but its still in the station and will be for some time unless I physically do something about it! So the below sketch would be how I'd cross the wires? Or in this case it looks like by crossing G2 to B1 it would tell me whats up?

    This is the same general idea behind the Luba kickstarter and the segway navimow. (GPS RTK)

    Personally I think the boundary wire is a better system than people give it credit for, its incredibly simple, it's a cheap solution and other than breaks its very reliable.

    The RTK systems are much more expensive. The open mower project requires $400 worth of GPS modules (2x $200) as well some other electronics as well as $100 worth of raspberry pis (2 x $50, if you can even get them). Also just as an FYI It also probably needs another $100 worth of components and PCBs and requires significant amount of electronics assembly skills to get it working.

    They are also much more complicated in terms of software and edge cases (what happens if your mower drives under a tree and blocks the GPS etc)

    Other than saving a couple of hours of installation of the wire, the GPS RTK only real advantage over the wire is the more efficient navigation, seeing as it doesn't need to travel randomly, it doesn't need to be out for as long. Which definitely has its advantages, but my wire mower isn't out on the lawn enough as it is for it to be a problem for us, so if it was out for half that time again, would it really be much of an advantage? Maybe a small amount of energy savings to be had every year, but nothing too significant.

    Saying that, I do think it will move that way over the next few years. It's not about it being a significant improvement, but its about it appearing like a significant improvement from a marketing point of view, and I think there is clearly a demand for it.

    It will be interesting to see how the Luba works when it's shipped at the end of the month (if it does). I expect it to have plenty of issues.

    I guess it’s the convenience of plug and play. My generation barely know what a landline is a boundary wire just seems old school when our iPhones can pinpoint our location our even an apple AirTag in a suitcase. Lack of wires would also mean family could borrow it for a trial, or use it in more than one location.



  • Registered Users Posts: 839 ✭✭✭ poker--addict


    Who was the irish seller? How are you both getting on with it?



  • Registered Users Posts: 222 ✭✭ Redlim


    Hopefully @navimow11 can help you out with the Irish seller they found but I don't think there's any active here yet. It's only been launched in a selection of countries so far and we both bought from Belgium - arrived at the end of last week. Stock seems very limited relative to demand due to the usual issues with semi-conductors etc. but Segway say they should have another batch in the coming months.

    In terms of the user side of things, I'm afraid I've nothing to report so far as I haven't had a chance to set it up yet. Hoping to have it up and running before next weekend.



  • Registered Users Posts: 2,371 ✭✭✭ Thud


    From what i’ve read the Segway Navimows have been having issues, unless you have a very open garden(no trees, bushes or buildings ) the gps is having issues and they are recommending you install a boundary wire anyway so don’t think the technology is there yet.



  • Registered Users Posts: 839 ✭✭✭ poker--addict


    have read this too, but limited pool of reviews, and those with issues will be the first to report. There is an antenna that can be bought also.



  • Registered Users Posts: 7,380 ✭✭✭ Raoul


    Hey guys, read through the thread but I only have a small lawn. @82 m^2. However, I still think a robot lawnmower makes sense as they are probably cheaper than the regular mower. Any recommendations? I saw the Landroid on amazon.de for €540, is this the best option?

    Also, has anyone gone the route of solar panel charging?

    @poker--addict @Redlim I was speaking with Lyster lawnmower in February and they said they were hoping to stock it in September/ October. I would be suprised if they make this date though. I only had time to set up mine correctly today and so far so good. It seems really accurate.. I did try and set it up last week and it wasn't 100% successful but there were probably a few different reasons for that. I can post a further update in a weeks time and let you know my thoughts! I would say that it definitely will not suit certain types of gardens.. there is a checklist on the navimow website that everyone should do before purchasing and it will give you a score based on the area surrounding your garden.

    Hi guys I have a 430x, this is its third season mowing, in its first year I had to replace the bearing housing in cutting disc, in its second season I replaced it twice..i am already after replacing twice this summer. I know this part needs replacing probably every season but mine seems to only last 6 or 7 weeks now.

    Machine not overworked and is well maintained. The only thing I can think of that might not be helping the problem is that I'm not using husky branded blades ??

    Can anyone suggest any other reason for this part to fail so frequently?

    Thanks



  • Registered Users Posts: 189 ✭✭ spose


    i use generic blades off Amazon and my 430x is in its 5th summer and I’ve never replaced that bearing.



  • Registered Users Posts: 458 ✭✭ RainInSummer


    Third or fourth year here with a 430X and I've never even heard of that part. Probably a bit late for warranty but if the issue was there from day one you might chance getting on to Husqvarna and see can you get any goodwill from them?



  • Registered Users Posts: 64 ✭✭ murfler


    I also cut at level 2, the guy in husky store mentioned it was too low and I was asking for trouble when I was cutting at level 1. What level to you mow?



  • Registered Users Posts: 64 ✭✭ murfler


    I change it myself so I doubt husky will stand over it. What height do you mow at? Thank you



  • Registered Users Posts: 189 ✭✭ spose


    I cut at 6. Have never tried to go that low. Doubt my garden would be smooth enough to cope with that



  • Registered Users Posts: 458 ✭✭ RainInSummer


    I cut at 2 for the first few years. 3 this year though.

    Maybe I'm mowing too low but that's like buying a bike with 8 gears but you can't use the first two gears
