Deck Wheel Bolts with Lock Nuts Replacement for Cub Cadet, Husqvarna - 137644, 738-3056, 193406, 73930600 (2 Pack)

What It Is

This is a set of two deck wheel bolts with matching lock nuts, designed to secure the anti-scalp wheels to the underside of a lawn mower deck. It’s a direct replacement for worn or missing hardware on select Cub Cadet, Husqvarna, and compatible MTD-built mowers.

Fitment & Compatibility

Before buying, confirm your mower uses a 5/16″-18 thread bolt (common on these brands). Cross-check your OEM part numbers: this kit replaces Cub Cadet 137644 and 738-3056, Husqvarna 193406, and 73930600. It fits most 42″ to 54″ stamped steel decks from those brands, but not fabricated or zero-turn decks with different bolt patterns. Measure your existing bolt length (typically 1.5″ to 2″) and compare to the included bolts—if your deck uses a longer bolt, this kit won’t work. Always verify deck model number (e.g., 42A, 46A) via your owner’s manual or stamped plate on the deck.

Key Things to Know

• Quality vs. OEM: These are aftermarket bolts, but users report tight tolerances and the same zinc-plated finish as factory hardware. The lock nuts have a nylon insert that holds well under vibration.
• Installation: Simple—use a socket or wrench. No special tools needed. Torque to about 10–12 ft-lb; overtightening can strip the deck threads or crack the wheel bracket.
• Common gotcha: The lock nuts are not reusable—if you remove them, replace with new ones (this kit gives you two, so you’re set for one wheel).
• Pack size: You get two bolts and two nuts. If your deck has four wheels, you’ll need two kits.

Should You Buy It

If you’re replacing missing or rusted deck wheel bolts on a compatible Cub Cadet or Husqvarna riding mower, this is a solid, low-cost fix. It’s not for zero-turn decks or decks with metric threads. For the price and high rating, it’s a no-brainer if your OEM part numbers match.
