The FR4000 is AMAZING under trees!

The FR4000 performs exceptionally well under trees

Impressive Hill-Climbing Ability!

I was genuinely surprised by the FR4000's hill-climbing capability! Even with its lightweight design, it easily managed to climb the small hill on my lawn without any trouble. It’s impressive to see such a compact machine handle slopes so effortlessly—definitely a great feature for uneven lawns

Superrrr

As an early user of the FJDynamics FR4000, I was excited to test its capabilities, and it hasn’t disappointed. It’s quiet, efficient, and the cutting quality is very uniform. I appreciate the advanced safety features, especially as I have pets that wander around the yard. It automatically stops if lifted or tipped, which gives me peace of mind. If you’re considering a robotic lawn mower, this one is definitely worth it.

Took a bit of time with the work zones and no go zones on the app, but once it was in place, the FR4000 has done all the work by itself.

Amazingly Accurate RTK Positioning

As one of the first users of the FJDynamics FR4000, I’ve been really impressed with its performance. As a user of FJDynamics’ agricultural navigation system, I’ve been impressed by their expertise in RTK technology. Knowing they are professionals in RTK manufacturing, I was confident when choosing their system, and it hasn’t disappointed. The precise RTK positioning makes such a difference in accuracy, and I’m glad to see they’ve applied the same advanced RTK technology to their robotic lawn mower,the FR4000’s cutting precision is excellent, and it manages to mow my entire lawn without missing any spots. I especially love how it adjusts to different grass heights and automatically returns to its charging station. This robot has truly freed up my hands!
