A leading municipal engineering department in Western Europe faced a critical dilemma: maintaining 120km of highway slopes with gradients ranging from 55° to 60°—a task that had become increasingly dangerous and inefficient. For years, the client relied on manual labor paired with conventional wheeled mowers, which resulted in two major safety incidents in 2022 (including a near-rollover accident) and an average daily maintenance output of only 800㎡. Additionally, their existing equipment failed to meet Euro 5 emission standards, risking non-compliance fines from local environmental authorities. The client urgently needed a solution that would eliminate operator risk, boost efficiency, adhere to strict emission regulations, and avoid turf damage on unstable slopes.
