This demonstration guide answers one field question about a machine parked on a packed-clipping deck. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with cool-down location. That reading separates a machine parked on a packed-clipping deck from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the muffler heat shield as the primary path. If it is in spec, do not replace the muffler heat shield just to complete a parts list.
Repair the failed system
The usual correction is the muffler heat shield, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about a machine parked on a packed-clipping deck.
Stop before you make it worse
Do not storing a hot mower against a plywood wall. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the muffler heat shield is corrected, convert the visit to a broader diagnosis rather than stacking parts.
