Read slope figures correctly
Manufacturers may state slope as a percentage or degrees; they are not interchangeable. Check whether the limit applies inside the working area, at the boundary, in wet conditions or only with an accessory. A lawn with dips, banks or drop-offs needs a site survey, not one maximum number.
| Check | Why it matters |
|---|---|
| Navigation | Boundary wire, RTK/GNSS, camera or beacon systems have different obstruction and setup limits |
| Traction | Grass condition, wheels, soil, slope direction and turning space affect grip |
| Safety | Lift/tilt sensing, blade stop, PIN/GPS and exclusion zones do not remove supervision responsibilities |
| Garden layout | Passages, steps, ponds, retaining walls, tree cover and multiple zones need explicit support |
| Ownership | Blades, battery, winter storage, service, theft cover and connectivity costs |
Safety boundary
Keep people, children, pets, wildlife and loose objects clear according to the instructions. Do not operate where the site cannot be made safe or the slope and edge limits are uncertain.
