This demonstration guide answers one field question about wet clippings that cement under the deck. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with deck-underside map after a wash. That reading separates wet clippings that cement under the deck from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the deck as the primary path. If it is in spec, do not replace the deck just to complete a parts list.
Repair the failed system
The usual correction is the deck, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about wet clippings that cement under the deck.
Stop before you make it worse
Do not pressure-washing a hot engine from above. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the deck is corrected, convert the visit to a broader diagnosis rather than stacking parts.
