This is maintained entirely by a pair of robot mowers in the picture.

Since September 2025, my Lymow fleet has mowed over 3 million square feet, logged 824 hours of mowing time, and covered nearly 69 acres of grass.

What surprised me most wasn't the time savings, it was the consistency.

The robots mow twice a week, every week, so the lawn never gets ahead of itself. Instead of mowing long grass and trying to force stripes into it, the entire property is constantly maintained at the same height. The result is striping that's incredibly precise and uniform across every slope, contour, and corner of the property.

This area used to take me about 4 hours per week on a tractor. I haven't touched the tractor since September. The robots have given me back almost 100 hours of mowing time already.

People always ask if robot mowers can handle hills. Looking at this picture, I'd say they're doing just fine.

The craziest part is watching them create perfectly parallel stripes over the entire property with RTK/GPS guidance. No overlaps. No fatigue. No "good enough" passes at the end of a long mowing session. Just even uniform stripes as far as the eye can see.

I never thought I'd be saying this, but after living with them for a season, I have zero desire to go back to spending my weekends on a mower.

Anyone else running robots on larger properties?

I was looking through my stats today and realized just how much work these robots have done.

My original Lymow One started mowing on September 19, 2025 and unfortunately bricked on May 25, 2026. It took a 3-month winter break (January-March) and still managed:

• 1,819,099 sq ft mowed
• 493.8 hours of mowing
• 41.8 acres cut

My Lymow One Plus joined the fleet on April 4, 2026 and has already logged:

• 1,183,060 sq ft mowed
• 330.4 hours of mowing
• 27.2 acres cut

Combined totals:

• 3,002,159 sq ft mowed
• 824.1 hours of mowing
• 68.9 acres cut

For comparison, I used to mow with a tractor twice a week. It took about 4 hours per week and burned roughly 2 gallons of diesel.

Over the 24.6 weeks that the robots have been handling the lawn, they've saved me approximately:

• 98.4 hours of mowing time, so a bit over 12-8 hour days mowing, or 2 full weeks of full time work mowing.
• About $5,170 in equivalent weekly-service mowing if I were to pay someone. I also mow 2x a week making my lawn looks even more fantastic, so a similar service would be over $10K!
• 49.2 gallons of diesel
• About $246 in fuel alone

The funny part is I haven't mowed with my tractor since September 19, 2025. It has basically been retired to aerating, snow blowing, and front end loading. I haven't even mounted the deck this year.

Even with the original One eventually dying, I can't complain too much. It cut over 41 acres before it gave up, and the One Plus picked up right where it left off. I still hope it gets fixed.

I know robot mowers aren't for everyone, but after almost 69 acres and 824 hours of autonomous mowing, I'm pretty convinced they're the future for larger properties.

What are your stats?

My Lymow One Plus controls cover/flap got ripped half way off and mangled when the mower went somewhere it apparently should not have gone. The original was damaged beyond repair, so I modeled and printed a replacement in ASA.

I made two versions:

One version uses a 1.5 mm stainless steel rod through the hinge for extra strength. I used a 100 mm rod, inserted it through the hinge, then snipped it to length.

The other version has a solid printed hinge in case you do not want to mess with the rod.

I also added the machine name to the top in the slicer, mostly because I thought it looked cool and a little more finished. Printed in ASA since it will live outside and needs to deal with sun, heat, moisture, and general mower abuse.

I posted the files on Thingiverse in case anyone else manages to send their mower on an adventure and destroys this flap too.

Edit: Clarify not stolen.

I started getting the E44 bumper stuck error on my Lymow One. The bumper itself was moving freely, but the mower kept thinking it was stuck.

After troubleshooting, I found the actual bumper switch was flaky. Sometimes it would register correctly, sometimes it would not. Obviously, you cannot just hop online and buy a new replacement switch, and dealing with support was becoming a hassle. At one point they wanted a picture of my RTK, which had nothing to do with the bumper switch issue.

So I designed my own drop-in replacement switch.

The goal was not to bypass the bumper safety system. I wanted the bumper to still work properly as a safety feature, just without the unreliable factory switch causing false E44 errors.

This replacement is designed to fit in place of the original switch without modifying the mower other than removing the old switch. Once installed, the bumper detection works normally again and the E44 error is cleared.

For anyone else dealing with E44, I would check:

Make sure the bumper moves freely

Check for debris or binding

Inspect the wiring and connector

Test the switch itself for intermittent/flaky behavior

Do not permanently bypass the bumper safety circuit

I made this because the mower was otherwise fine, but a flaky switch was taking it out of service.

Has anyone else had the E44 bumper stuck issue on the Lymow One?

Edit to add more diagnostic info.

Hold Home for about a second to toggle

On the info screen, look for the FNT line. The bumper status is the second digit after FNT.

The values are:

0 = no bumper switch pressed
1 = right bumper switch triggered
2 = left bumper switch triggered
3 = both bumper switches triggered

So with the mower sitting still and the bumper not touching anything, that value should be 0.

Then manually press the bumper:

Press the right side of the bumper → it should change to 1
Press the left side of the bumper → it should change to 2
Press the bumper in a way that hits both switches → it should show 3
Let go → it should return cleanly to 0

In my case, #2 left side would either stay triggered, fail to trigger, or flicker/intermittently change when I barely touched the switch. That confirmed the bumper itself was not mechanically stuck the switch was flaky.

Basically:

Shows 1 or 2 with nothing touching the bumper = that side is falsely reporting pressed
Doesn’t change when you press that side = that switch may be open/bad/disconnected
Flickers between 0 and 1/2 = flaky switch or bad connection
Shows 3 all the time = both sides are being reported as pressed, or there may be a wiring/common issue

That is how I narrowed it down before designing the drop-in replacement switch.

I modified the flaps that cover the contacts and the ball ends to accept standard 100mm rods.

I have the zones between my One and One+ overlapping slightly. They figured it out fine.

A bit of trial and error to get it right. Yes, that is a deer in the pipe that was hit by a car on the road. Country living.

For a mile anyway.
