This demonstration guide answers one field question about a bent blade or unlevel deck after a curb strike. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with blade tracking measured at four deck points. That reading separates a bent blade or unlevel deck after a curb strike from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the blade and deck-wheel set as the primary path. If it is in spec, do not replace the blade and deck-wheel set just to complete a parts list.
Repair the failed system
The usual correction is the blade and deck-wheel set, 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 bent blade or unlevel deck after a curb strike.
Stop before you make it worse
Do not sharpening a hooked blade without checking for a bend. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the blade and deck-wheel set is corrected, convert the visit to a broader diagnosis rather than stacking parts.
