Mow overheat message – Last stop cause 31
Step 1
Is it the first cut of the season or is the grass very high?
• If Yes – Raise mowing height level to the highest, 100, and let the mower complete full cycle
(2-3 days). Then gradually, over a few days, lower the height of cut to what you need.
• If No – Go to Step 2
Step 2
Turn the mower Off, remove the safety key from the stop handle and lift the mower up to a position
allowing you to inspect its mowing deck and blades as illustrated below – Use heavy gloves when
reaching towards the mowing deck, mowing disk and blades.
Check the following:
1. Any objects blocking the mowing disk rotation such as branches, toys, ropes etc.?
Remove and free mowing deck from all debris. See how to remove mowing disk here:
Replace blades disk
2. Use heavy gloves and see whether blades rotate freely or stuck on their axle – clean and
make sure blades rotate freely
3. Are the blades dull? Replace blades as needed
4. Is the mowing height set too low for a very high grass? If it is, raise the mowing height to
max and slowly – over days - reduce it
