What torque should I use on a Wright blade bolt?
Wright blade bolt torque is typically 70–80 ft-lb (95–108 N·m). Threadlocker: Wright torque table lists "Thread Locker: N/A" for blade bolts. Always confirm the exact figure for your specific model — deck design, blade thickness, and spindle stack-up move the spec by 10–20 ft-lb between models in the same brand line.

Pro tip for Wright blade service
Wright's blade bolt is a coarse 5/8"-11, not the 5/8"-18 fine thread common on other decks — a 5/8"-18 replacement will not thread on. Wright's parts lists say "refer to Owners Manual for all critical torques."
Step-by-step Wright blade-bolt reinstall
Disconnect the spark plug, engage parking brake, tip the mower (carb-side up). Block the blade with a 2×4 — never your hand. Use a 1/2" drive breaker bar with a 6-point socket. Clean threads with brake cleaner. No threadlocker needed unless your model manual specifies it. Torque in one smooth pull with a calibrated torque wrench. Re-check after first hour of cutting.
