WHERE GRANDE 44 WORKS
WHY BURRO
It actually works.
Rough terrain, dense canopy, changing conditions — Burro has been tested where it counts. Deployed and working across nurseries, vineyards, yards, and more. Not waiting on a roadmap.
It’s easy to use.
One-time setup. Map your routes in BOSS Web. Set your speed, stops, and destinations. Press start and go.
Support that doesn’t end at the sale.
Grande 44 wasn’t built to collect dust in your shed. We train, deploy, and support every Burro alongside your team — all day, every day.
One machine. More ROI.
Set the route and send it out. Your operators focus on the work that actually needs a human. Burro handles the rest.
