Here is where I am at today:
Yarbo’s first mow was May 8, 2025. My map looked nothing like it does today.
Live and learn.
Areas:
- Front West Lawn
- Front East Lawn
- East Driveway East Lawn
- West Driveway East Lawn
- Back West Lawn
- Back East Lawn
- North Lawn
There is still a West Driveway West Lawn to map and mow, but that area is currently a collection of trash and tree branches from I’d guess about a hundred years of no one cleaning out the fence row.
I’ll get it mapped in time…
The property is in central Ohio and is about 2.9 acres.
The property is mostly flat. Topo map shows maybe 5 feet of elevation gain.
There are woven field fences between these areas:
1-4, 1-5, 4-5, 5-7, 6-7
There is a fence to the East of 6 but I have not mapped that area due to some needed cleanup to the overgrown brush in that area before I’ll let Yarbo loose over there.
In time…
To get decent looking cuts I’ve made the following changes to settings:
- Changed overlap to 8 inches. (increases mowing time significantly)
- I’ve recently switched to 4 perimeters.
- I mow perimeters first.
- I mow at the fastest speed available.
A sample mowing time from today:
Mowed the North Lawn today. 13,100 square feet. Estimated mowing time was 4 h and 43 min.
I started the work plan at 10:50 and the battery was at 96%. The work plan was complete at 18:40. Total time start to finish was 7h 50m. Yarbo happily charged and went back to work as advertised.
All 7 areas mowed in 4 days. There was some downtime for maintenance a couple times in those 4 days. (Cutting height motor overcurrent, track grease, and a couple baths for the mower. Mowing overnight ends up with some buildup as the grass gets wet from dew)
I originally had my charging station too close to the house and Yarbo would lose GPS signal while charging. This caused lots of “map drift”. I have since moved the charging station further out in the yard and Yarbo maintains GPS while charging and “map drift” has not re-occurred.
My data center is in my attic. I know this isn’t the recommended installation but it seems to be working pretty good for me. YMMV.
Could it be affecting accuracy requiring me to up the overlap to 8 inches, I suppose it could. But it is currently seeing 21 Satellites.
I’m still adding no go zones as I come across areas where Yarbo gets confused or does a crappy job of getting all the grass.
Area 6, in the north part of the lawn there are 4 fruit trees (circular no go zones) and a rectangle no go zone that is a grape vine. Yarbo does a really bad job of the area between the grape vine and the fence between areas 6 and 7.
A couple questions:
- Anyone know how to get the google map larger to cover my entire property?
- Any suggestions for map changes?
- Any suggestions for more efficiency?
