RMI 632
Smart robotic mower with mulching function
General
The STIHL RMI 632 iMOW® robotic mower is an all-rounder if you want to mow a large lawn automatically. It has a powerful lithium-ion battery and a cutting width of 28 cm, enabling it to cope with lawns of up to 3,000 m² with ease. The mulching mowing deck transforms the grass blades into fine clippings, which are reabsorbed by the soil as natural fertiliser. You can set the desired grass height individually to 15 settings. For a uniform cutting pattern, the adaptive slope speed function adapts the motor power to the terrain conditions. The RMI 632 can handle gradients of up to 45 %. In the event of contact with an object on the mowing area, the movable hood with sensors detects the obstacles and the iMOW® robotic mower changes direction. The integrated LCD display, which is part of the removable control panel, is used for information or input. It can be used to find out information about the current charge status of the robotic mower or make entries in the dynamic mowing plan. An installation kit is required for installation. The STIHL iMOW® robotic mowers comply with all applicable safety standards. Nevertheless, the iMOW® robotic mower is not a toy. During the iMOW® robotic mower's active times, in particular children, bystanders and animals must be kept out of the working area. Please refer to the operating instructions for further information.
