918-04822B Spindle Assembly Fits for Craftsman Cub Troy Bilt Pony Bronco 42" Mower Deck Tractor, Come with All Mounting Hardware Include Threaded Bolt, Replace 918-04822A 618-04822

What It Is

This is a replacement spindle assembly for the 42-inch mower decks found on many Craftsman, Cub Cadet, and Troy-Bilt lawn tractors (like the Pony and Bronco models). It drives the mower blade and includes all mounting hardware, including the threaded bolt, so you can swap it in without hunting for extra parts.

Fitment & Compatibility

• Deck size: Designed specifically for 42-inch mower decks. Measure your deck width (cutting path) to confirm.
• Brands/models: Fits Craftsman, Cub Cadet, Troy-Bilt Pony, and Bronco tractors, plus some Huskee, Poulan, and MTD models with a 42-inch stamped deck.
• OEM replacement: Replaces OEM part numbers 918-04822A and 618-04822. If your original spindle has a different number (e.g., 918-04822C), measure the bolt pattern and shaft diameter before ordering.
• Measurements: Verify the spindle shaft diameter (typically 1-inch) and the mounting bolt pattern (usually 3-bolt, spaced 3 inches apart). Deck thickness can vary—this assembly fits most standard stamped decks.
• What to check: Look at the existing spindle for a part number label. If missing, remove the blade and measure the shaft diameter and bolt hole spacing.

Key Things to Know

• Includes hardware: Comes with the mounting bolt and lock washer—no need to buy extra fasteners. Use a torque wrench (around 40-50 ft-lbs on the blade bolt).
• Installation difficulty: Moderate. You’ll need a jack to lift the mower, a socket set, and possibly a puller if the old spindle is seized. Expect 30-60 minutes per spindle.
• Quality note: Aftermarket part, not OEM. Most users report it’s a solid match for the original, but inspect the bearings for smooth rotation before installing.
• Common gotcha: The spindle housing may be slightly taller or shorter than OEM—check blade clearance with the deck shell before tightening everything.

Should You Buy It

If you have a 42-inch Craftsman, Cub Cadet, or Troy-Bilt tractor with a worn or noisy spindle, this is a reliable, budget-friendly drop-in replacement. It includes all hardware, so it’s a straightforward fix for DIYers. Skip it only if you need an exact OEM match for a warranty claim or a non-standard deck size.
