A Husqvarna. We've had Worx and Husqvarna and the Husky wins hands down

Installing the wire is easy enough - just roll it out and peg it down
Thank you, like the look of the 315.



Has anyone got any experience of Cobra? Is it a buy cheap, buy twice type job?

Can someone post a link to the detectors used by folk mentioned here to find a broken wire please?

My Lawnmaster L10 arrived yesterday, wired in last night and running today between shows. Loving it so far, it is relatively subtle (mostly black, some orange) and very quiet. Seems to be cutting well, installation and set was dead easy. Lawn is probably around 250SQ meters. It's actually really fun to watch, the dogs lost interest quickly, great purchase for day 1!
Be interested to see how you get on.
How flat is your lawn? Mine is quite bumpy in parts.

Flymo one is dirt cheap.

It recommends 400m2 - could you have double the area and work it like a dog, or does it not work like that?

I think you'll find that they don't have any stock for delivery or collection, sadly! That was my experience anyway!

Ours will do 100m² in around 2.5 hours a day. So you could run it 20 hours a day and cover 800m² but it may degrade the battery quicker.
They are cheap enough to replace though.

I think the newer (Flymo at least) models have a maximum run time / day to stop you using a smaller capacity on a larger lawn (I think they manage this with a minimum standby over 24 hours but didn't really concentrate on that bit of the instructions when setting up).

I guess you could just have the lawn cut over a larger number of days and more 'missed bits'. The older models may not have this limitation of course.

It's brilliant! Ran about 40 mins yesterday and today (heavy rain other times) and its brought the lawn under control even though wet. No before pics, but lawn grows very fast and in clumps so this should help it get to a more consistent length and colour. I used to like the stripes but they never lasted long. Lawn is pretty flat. Mower lives by the palm, I misread that it needs a meter either side - it doesn't, it needs a meter in total so I could have hidden it better (not taking up wire to redo). Will build it a house this weekend.

They don't but they are £415 direct from Flymo on eBay with an extra 10% or 20% discount available. I paid £325 ish.

I scarified my lawn and now have breaks in the cable. reckon it's going to be worth trying to track them down or just pull it all up and recable? Lawn is about 200 m².

Our mower (Worx landroid) has developed a strange problem - it runs normally but stops when it's about 4 metres from the perimeter wire and says it's outside its working area. Pushing it a bit closer to the wire starts it again.

Has anyone come across this - would the cause most likely be the wire has been almost cut at some point or a connector is faulty and the resistance is too high and it can't send a signal to it and the solution is to replace the wire (or possibly add bits that extend into the area of the garden that's a long way from the perimeter). It seems to have a resistance of about 200 ohms from one end to the other (probably about 250 metres), which seems a little bit high but I'm not an electrical engineer.

Having now been round mine and fixed seven breaks, I can say that 200 sounds high, I was getting 2 ohms end to end on about 40 metres of cable.

Having checked specs it should be about 4 ohms per 100m.

Thanks - I think I'll need to go through it all carefully and replace the wire if I can't see anything obvious.

Most times you can use an AM radio - disconnect one end of the boundary wire from the base station leaving the other connected, tune an AM radio to static and hold it close to the wire and you should hear it ticking (you may need to play with LW / MW / SW to find the strongest signal) - follow it round until it stops ticking or gets faint and that should be where your break is. If you have guide wires you will probably need to disconnect those while you do this as well.

You can also narrow down the area where the break is by swapping a guide wire connection for the boundary wire which 'splits' the garden in two so you know which side to focus on.

I've found a few breaks on our Husqvarna setup using this method.

As recommended by many on another thread I bought the Flymo 1200R, but I seem to have a duff one. Basically it just doesn't work at all, and after a bit of experimentation I'm pretty sure its the front sensor being overly sensitive.

When you try and use it, it doesn't move forward more than a couple of feet before stopping and changing direction. Even placing it close to the guide wire it took 4 attempts to manage to get home, with me having to reset it each time. On every occasion I get the front collision fault error. So I went into the advanced menu (hold 7+9 keys on the menu screen) and experimented on the sensor menu. When pushing from the rear, or either side I need to give it about a cm push before the sensor triggers. But from the front I barely have to touch it and it triggers - I mean I'm not even pushing, just placing my hand on the front edge is enough to trigger it.

Does anyone else have this problem and were they able to fix it? Right now its a very expensive ornament :-(

I'm trying to guage
1) suitability for a robot mower
2) which one

The blue dotted line is 165m and the green dotted line is 75. The bottom left hand corner is water, and inside the red line, that border is a hedge. You can see drive, car turning place and garage. Obviously various other sheds, trampolines etc.

Any thoughts? My first thoughts are that setting the guide wires would take an age, and that the area is quite large at about 12000m^2
I have a large space like this with trees and obstacles, have you found anything suitable as yet?

Suggest you talk to Flymo, unless they can offer a solution that works for you send it back for replacement.

Yeah I think that's what it will end up as. I did manage to get it working for a while, I don't know how exactly, I was holding it at different angles hoping the sensors inside might somehow recalibrate, and sure enough I managed to get 30 minutes out of it before the problem repeated. Since then its been a mostly negative experience - every time its got started I'll come back to a sensor error within a few minutes.

Sounds very annoying, hopefully, Flymo will sort you out quickly!

We've got our 1200R set up at the new house now - one main lawn for auto mowing once a day and two smaller ones that I'll take him over to mow every so often in manual mode. Been pretty impressed with how easy it was to get the boundary wires configured - unfortunately, there's no grass link otherwise it would have been fun to see if it could be set up automatically.

Landroid is committing suicide over one edge of the lawn. Same place every day. Boundary wire is intact and at the recommended distance. Annoying but it's cutting beautifully at 40mm.
