The first commercial class, self-driving Robotic Mower is here.
Starting Spring 2019, you can trial our Robotic Mower for 60 days at a low trial cost.
The Robotic Mower is ideal for many large-scale mowing jobs
Parks & Bike Paths
Trails & Open Space
Reduce Labor, Save Money & Have A Healthier Lawn
Reduce the Cost of Labor
Unlike a riding mower, no operator is needed
No supervision required, simply start it on its path and it runs automatically
Reduces chance of mowing-related injuries.
Get Dramatic Cost Savings
No mower operator = much lower cost of labor
Robotic Mower a fraction of the cost of a commercial large-field tractor and mowing deck
Starts at $38,995 + annual software subscription.
Mow More Often for a Healthier Lawn
Mow autonomously 24/7
More frequently-mowed lawns require less water
Shorter clippings easily composted back into turf.

About the Robotic Mower
Fits on a trailer used to transport a typical riding mower
Onboard computer connects to Robot Operations Center
Can be started and monitored via mobile phone app
Pauses automatically when sensors detect obstacles in its path
Operates using both cellular and GPS data
63” wide mowing deck
Operates at 5 MPH to mow over 3 acres per hour
Cut height range of 0.5″ to 6″
Gas-powered, able to mow approx. 25 acres on one tank of gas
Accesses pre-programmed area path to begin work
Onboard cameras automatically take Before and After photos
How the Robotic Mower Works
Capture perimeter of the field in which the Mower will operate
Local operator travels field perimeter with a simple Area Collection Tool to capture GPS location data.
The captured field description data is uploaded to the cloud-based Robot Operations Center (ROC) where it is transformed into a program.
Mowing program is stored in the ROC to be accessed by the Robotic Mower when ready to start work.
Mower is easily operated
The gas-powered Robotic Mower is transported on same-sized trailer as a typical riding mower.
Local operator opens ROC app on their mobile device, chooses the program to run, and presses Start.
Self-driving Robotic Mower doesn’t require an operator once it’s running.
Mower is connected to the cloud
Its onboard computer downloads the mowing program and starts mowing.
Can be monitored in real time from the ROC web dashboard or mobile app.
Captures location and weather data, as well as Before & After photos.
Sensors detect obstacles
Robotic Mower pauses if something passes in front of it.
Stops if there is an unexpected obstacle in its path. Notifies ROC, which sends mobile notifications to local operators along with picture of the obstacle.
ROC provides real-time monitoring & data capture
The ROC Dashboard gives live status updates on all your Robotic Mowers.
Time stamped data is automatically compiled into detailed Job Completion Reports.
Reports with photos provide essential records to minimize insurance & business risk.
Job Reports provide proof of job completion to your customers.
Have peace of mind knowing a Left Hand Robotics expert is available when you need them.
As the mower is connected to the ROC, we can fix many on-hardware problems over the air.
Receive over the air software upgrades and patching.
If you have questions, you can reach a Support Expert.
Gold level Customer Support includes phone support M-F 7a-7p MT, plus 24-hour email support.
