Noises heard from mower
Step 1
1. Turn the mower off and remove safety key from stop handle.
2. Put on heavy gloves. Lift the front of the mower and check if there is any visible reason that
can make the noise with regards to the mowing system or drive system.
Possible reasons are:
• Debris stuck in the drive wheels or front wheel.
• Debris stuck in the mowing deck.
• Bent blade or damaged mowing disk.
• Bent mowing motor axle.
• Too much mulched grass built up between mowing deck and blades.
Was it any of the above mentioned and you cleaned or fixed it? Took care of the noise?
• If Yes – Problem solved
• If No – Go to Step 2
Step 2
Run the following diagnostics using RoboTools, and follow the instructions within
• Obstruction Test
• Lift & Load
• Caster Wheel
• Mowing System
• Driving System
Have all tests passed (after addressing issues found during the test)?
• If Yes – Go to Step 3
• If No – Consult with Level 3 technical support.
Step 3
Send the mower to mow (Mowing motor working). Can loud noises be heard from the mower?
• If Yes – Replace the blades and the disk accordingly, and let the mower complete the next
few operations to understand if the problem was one-time thing or recurrent.
• If No – The noises were probably temporary. Keep running the mower for a while. You
should consult Level 3 technical support in case of doubt.
