Robot mowers

[Ralston Boy]

How do these things know where to go (and not to go)? Do you need to put some sort of "invisible fence" around the perimeter, flower beds, driveway, etc?

9 acre lawn??!??

Some of them are programmed others you use a control like you would for a RC airplane or boat.

That what I'm curious about, how big is the area it mows exactly?

If I were in a residential setting with say 1/4-1/2 after or lawn, I think it would be a no-brainer.

It sounds Ike most of them are best for flat, small residential type properties.

Some of them are designed to handle bigger, rural properties. Lymow is one. Yarbo is another..that one has a modular system that can (optionally) also do snow blowing.

The older ones required a buried wire. The ones for larger properties let you set the boundaries with an app. They have sensors to avoid obstacles.

That new Lymow would cover the 9 acres about once every 5-6 days.

Yeah the Lymow One Plus 10a looks decent.

I saw one mowing just the other day. It was pretty large and yellow. There was a guy standing nearby, but I don't know if he was operating it or just watching it. It was mowing a pretty large area. I expect they're expensive too.

Edit: It might have been one like this. Yarbo
Not cheap, but not exactly expensive either, compared to what ZT's cost.

Question for Lymow owners: How do they handle obstacles?

I'd divide obstacles into two classes. The first is when you hit something that you can't move over, could be a stick in the grass, could be just tall grass. The second is something that could damage a blade, which the mower can move over, like a rock or a stump. Does the Lymow detect that sort of contact and brake the blade and back up?

Here’s the spec. I’ve had good luck with the avoidance but have had an occasional glitch with some rock garden borders. So far I’ve mapped a little over 1 acre and it’s not a flat smooth property. 230 year old New England farm property;lots of walls ,rocks, stumps and hills, pond etc. Got original one last October. Upgraded to the plus and gave the original to son.

I’ll try to do a detailed review when I get on a computer and not phone.

Making me think of adding old "Cow Catchers" like on the front of old steam trains. Cowcatcher - Wikipedia
