MTD 983-04511 Brake Shell Assembly 46" Deck for Murray Troy-Bilt Yard-Machines XP Pony Horse Bronco 775S 795S 795T 42

What It Is

The MTD 983-04511 Brake Shell Assembly is the OEM replacement part that houses the brake components for 46-inch cutting deck mowers from Murray, Troy-Bilt, and Yard-Machines. It’s specifically designed for models with manual or electric blade engagement systems, including the XP, Pony, Horse, Bronco, 775S, 795S, and 795T series.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 46 inches—this part will not fit 42-inch or 48-inch decks. Check your model number against MTD/OEM part 983-04511; it replaces older part numbers 983-04511A and 983-04511B. This is an OEM part, not an aftermarket clone, so it matches factory specs. Measure the mounting hole spacing on your current brake shell (typically 4.5 inches center-to-center) and confirm the pulley diameter matches your belt setup (usually 4 inches). If your mower uses a different brake design (e.g., side-mounted or cable-actuated), this won’t work.

Key Things to Know

• Quality: Cast aluminum shell with steel brake band—holds up well under normal use, but inspect the new brake pad material for even thickness before installing.
• Installation: Moderate difficulty. You’ll need to remove the deck, detach the blade, and disconnect the brake cable. Expect 30–60 minutes. A pulley puller may be required if the old shell is seized.
• Common gotcha: The brake band alignment tab can snap if overtightened. Use a torque wrench (specs: 20–25 ft-lbs on mounting bolts). Also, check the blade spindle bearings while you’re in there—worn bearings will kill the new shell quickly.
• Compatibility note: Fits both manual and electric PTO systems, but the cable routing differs. Keep your old cable bracket if the new one doesn’t match.

Should You Buy It

Buy this if your current brake shell is cracked, worn, or no longer stops the blade within 3 seconds. It’s a direct OEM fit for 46-inch Murray, Troy-Bilt, and Yard-Machines mowers with the listed model series. If you’re on a tight budget, an aftermarket shell might save $10–15, but expect fitment issues or shorter lifespan. This is the right choice for a reliable, hassle-free replacement.
