eXmark Mower Blade Bolt Torque Specs
eXmark Lazer Z, Radius, and Quest commercial Z-turns share Toro engineering and use a 15/16" blade bolt with a Belleville-stack washer assembly; the spec is intentionally identical to Toro Z-Master.
What torque should I use on a eXmark blade bolt?
eXmark blade bolt torque is typically 95–110 ft-lb on a 15/16" socket with 5/8"-18 UNF thread. Threadlocker: Blue Loctite 242 recommended on Lazer Z. 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.
eXmark Radius X 52" Zero-Turn blade bolt torque
95–105 ft-lb on a 15/16" socket, 5/8"-18 UNF thread. Belleville washer cup-side toward bolt head. Replace washer if deformed.
eXmark Lazer Z X 60" Commercial Zero-Turn blade bolt torque
100–110 ft-lb on a 15/16" socket, 5/8"-18 UNF thread. Apply Loctite. Cross-compatible with Toro Z-Master hardware.
Pro tip for eXmark blade service
eXmark Lazer Z blade bolts (P/N 109-6465) are cross-compatible with Toro Z-Master P/N 109-6465 — same part, different stickers. Source whichever is cheaper at your local dealer.
Step-by-step eXmark 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. Apply Blue Loctite 242 recommended on Lazer Z. Torque in one smooth pull with a calibrated torque wrench. Re-check after first hour of cutting.
