A study conducted at the University of Kentucky tested whether Husqvarna robotic mowers could maintain high-quality turfgrass with less fertilizer compared to traditional rotary mowers.
Key Findings:
Healthier Turff with Less Fertilizer:
- Grass maintained with robotic mowers using less fertilizer (1.6 lbs. of nitrogen per 1,000 sq. ft.) performed as well as or better than grass mowed with a rotary mower using more fertilizer (2 lbs. of nitrogen per 1,000 sq. ft.).
- During stressful summer months, robotic mowers helped maintain better turf health (measured by NDVI values).
Better Grass Color and Quality:
- Robotic mowers consistently maintained turf color and quality comparable to, or better than, rotary mowers.
- While rotary mowers showed slightly better results on a few dates, these differences were likely due to random variations in the measurement process rather than actual performance.
Frequent Mowing for Optimal Results:
- The robotic mowers cut the grass twice a week, while the rotary mower cut it only once a week.
- More frequent mowing with robotic mowers contributed to even grass growth and a healthier lawn.
Ideal for Already Healthy Lawns:
- The study suggests that robotic mowers work best when starting with a healthy lawn. If a lawn is already in poor condition, reducing fertilizer may not yield the same strong results.
What This Means for Customers:
- Save Money on Fertilizer: Robotic mowers allow you to use less fertilizer while still keeping your grass healthy and green.
- Healthier Turf in Hot Weather: Your lawn stays in better shape, especially during summer heat stress.
- More Even, Consistent Mowing: Robotic mowers cut frequently, leading to a well-maintained and professional-looking lawn.
- Eco-Friendly Lawn Care: Reduced fertilizer use and continuous mowing help create a more sustainable lawn care routine.
This study shows that robotic mowers are not just convenient—they actively improve lawn health while reducing maintenance costs and environmental impact.
