Agree w/ other poster -- virtual certainty they're RH thread.

If this is follow-up to the post of hard to break loose, use a block
to wedge in between the blade tip and the deck to hold the blade and
get a good 1/2" or larger socket set and breakover handle to get the
torque needed. If need it, add a cheater.

If that doesn't work easily, borrow/rent an impact wrench. The hand,
hammer-actuated type are a little clumsy but can be effective. The
final recourse is heat, but would be unlikely to need it.
