Answers for professionals
The BM-850 GPS-RTK is designed for football pitches, sports fields and municipal parks. It mows up to 30,000 m² three times a week, depending on irrigation frequency and pitch usage, which in practice covers three to four standard football pitches. Its 42 cm cutting width and two floating heads ensure an even sports turf and safe operation.
The BM-850 specialises in sports fields (football, rugby), with a capacity of around 30,000 m² three times a week. The BM-1050 targets large green spaces, parks and public sites, covering up to 45,000 m² with Wisenav® and three floating cutting heads. The right choice therefore depends mainly on the area to mow, the cutting width and the type of terrain: uniform sports turf or mixed areas.
The total cost combines the purchase of the robot, the charging station, installation and annual maintenance. Electricity consumption remains marginal (around €200 per year) for a professional robotic mower. To compare with your current mowing costs (fuel, labour hours, depreciation of the ride-on mower), simulate your situation with the cost calculator.
