When to Call a Professional
Contact a Stihl dealer if the tilt sensor continues triggering on level ground, as this may indicate a faulty sensor. Professional landscaping may be needed for extensive terrain modification or if your yard has unavoidable steep slopes requiring alternative mowing solutions.Frequently Asked Questions
What slope angle is too steep for Stihl iMOW?
Most Stihl iMOW models can handle slopes up to 25-35 degrees depending on the specific model. Check your owner's manual for exact specifications, as newer models may have different capabilities.
Can I disable the tilt sensor on my Stihl iMOW?
No, the tilt sensor is a critical safety feature that cannot and should not be disabled. It prevents the mower from tipping over or operating unsafely on steep terrain.
Why does my iMOW tilt sensor activate on seemingly flat ground?
This could indicate small dips, holes, or uneven spots in your lawn that aren't immediately visible. It might also suggest a faulty tilt sensor that requires professional diagnosis and replacement.
How do I set up no-go zones for steep areas?
Use the iMOW app to create virtual boundaries, or install physical boundary wire around steep areas. The app method is easier and allows for quick adjustments without rewiring.
Will the tilt sensor error damage my mower?
No, this error is a protective feature designed to prevent damage. The mower stops operation when tilted beyond safe angles to protect both the machine and your lawn from potential harm.
