Collision sensor problem

Collision sensor problem, front/rear — Mower body movement restricted

husqvarna · Automower 105

What does Collision sensor problem mean?

The robotic lawnmower's collision sensors are detecting an issue, likely because the mower body is not able to move freely around its chassis. This can prevent proper operation and obstacle detection, causing the mower to stop or behave erratically.

Common Causes

  • The mower body is physically restricted and cannot move freely around its chassis.
  • Debris or an obstruction is interfering with the mower's chassis movement.

Repair Steps & Checklist

  3. 3

    If the issue persists, inspect the collision sensors for damage or blockages.
