4-Pack 193406 137644 Deck Wheel Shoulder Bolts and Lock Nuts Compatible with Cub Cadet Craftsman Husqvarna Lawn Mower Deck Wheels, Replaces 532193406 184219 532137644 738-3056 938-3056 73930600

What It Is

This is a 4-pack of shoulder bolts and lock nuts designed to mount lawn mower deck wheels (often called anti-scalp wheels) on select Cub Cadet, Craftsman, and Husqvarna mowers. They secure the wheel to the deck bracket, allowing the wheel to spin freely while preventing it from falling off.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck wheel bolt size: These bolts are M8 x 1.25 thread pitch with a 19mm shoulder length. Measure your existing bolt’s shoulder (the smooth section under the head) – it must match 19mm for the wheel to sit correctly.
• OEM part numbers: Replaces 532193406, 532137644, 184219, 738-3056, 938-3056, 73930600. If your mower uses any of these, these bolts are a direct fit.
• Brand/model cross-check: Compatible with many Cub Cadet (LT, GT, RZT series), Craftsman (LT1000, LT2000, DLT series), and Husqvarna (YTH, LTH, GTH series) mowers with 11-13 inch deck wheels. Not for zero-turn mowers with 8-inch or smaller wheels. Check your deck’s wheel bracket hole diameter – should be 8mm.

Key Things to Know

• Hardware quality: Bolts are zinc-plated steel; lock nuts have a nylon insert to resist vibration loosening. Adequate for residential use, but not as tough as grade 8 hardware for heavy commercial mowing.
• Installation difficulty: Easy – swap one bolt at a time. Use a 13mm socket for the bolt head and 13mm wrench for the nut. No special tools needed.
• Common gotcha: Shoulder length must match your wheel’s thickness. If your wheel is thinner than 19mm, the bolt will pinch the wheel too tight; if thicker, the wheel will wobble. Measure before buying.
• Pack contents: 4 bolts + 4 lock nuts – enough for a standard 4-wheel deck. No washers included; you may need flat washers if your bracket is thicker than 2mm.

Should You Buy It

Right for you if you have a Cub Cadet, Craftsman, or Husqvarna lawn tractor with deck wheels that use these specific OEM bolt numbers, and you need a quick, affordable fix for lost or worn bolts. Skip it if your mower uses a different shoulder length (e.g., 25mm) or if you need bolts for a zero-turn mower with smaller wheels.
