What torque should I use on a Bad Boy blade bolt?

Bad Boy blade bolt torque is typically 90–110 ft-lb on a 15/16" socket. Threadlocker: Not called for in the Bad Boy manuals cited below. 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.

Bad Boy Maverick (54" Deck) blade bolt torque

90–110 ft-lb on a 15/16" socket. Maverick Owner's Operator Service Manual (2021, p.31, "Blade Removal"): "Re-torque the blade bolts to 90-110 ft-lbs. upon reinstallation." Same paragraph: "Use a 15/16" socket" — the "impact wrench capable of... at least 220 ft-lbs" in that sentence is a removal-tool rating, not a tightening spec. Right-hand thread; diameter and pitch are not stated.

Bad Boy Rogue (61" Deck) blade bolt torque

90–110 ft-lb on a 15/16" socket. Rogue/Outlaw Owner's Operator Service and Parts Manual (2020, p.31, "Blade Removal"): "Re-torque the blade bolts to 90-110 lbs. upon reinstallation." (the manual drops the "ft-"; the Maverick manual prints the same spec as 90-110 ft-lbs). Same page: "Use a 15/16" socket... A 3/4" wrench can be used on the spindle shaft above the blade to keep the shaft from turning. The bolt has right-handed threads." Thread diameter and pitch are not stated.

Pro tip for Bad Boy blade service

The Bad Boy manuals mention "an impact wrench capable of... at least 220 ft-lbs" — that is a removal-tool rating, not a tightening spec. Reinstall to 90–110 ft-lb with a torque wrench, holding the spindle shaft with a 3/4" wrench above the blade.

Step-by-step Bad Boy 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.
