2 Pack 783-06424A-0638 Deck Spindle Pulley Belt Guard Cover for MTD Troy-Bilt Craftsman 42" 46" Riding Lawn Mowers Parts Replaces 783-06424A Includes Mounting Bolts

What It Is

This is a set of two deck spindle pulley belt guard covers for MTD, Troy-Bilt, and Craftsman riding lawn mowers with 42-inch or 46-inch cutting decks. They protect the spindle pulley and belt from debris and accidental contact, and include mounting bolts for a direct swap.

Fitment & Compatibility

• Check your deck size: This guard fits only 42" and 46" decks. Measure your deck width to confirm.
• OEM part cross-reference: Replaces OEM part 783-06424A. If your current guard has that number, this is a direct match.
• Brand compatibility: Works with MTD, Troy-Bilt, Craftsman, Huskee, Yard-Man, and Cub Cadet models that use the same deck. Most common on 2000–2010 models.
• Physical check: The guard measures roughly 6" x 4". Measure the mounting hole spacing on your deck (center-to-center) to ensure it matches—typically 2.5" on these decks.
• Includes bolts: Comes with two bolts; no need to buy hardware separately.

Key Things to Know

• Material: Made from stamped steel with a black powder coat. Durable but can rust if paint chips—touch up if needed.
• Installation: Simple bolt-on job. Remove the old guard (usually two bolts), align the new one over the spindle pulley, and tighten. No special tools required.
• Common gotcha: Some decks have a slightly different bolt pattern on older models. Measure first to avoid return hassle.
• Quantity: You get two guards, so you can replace both spindles at once. If you only need one, you’ll have a spare.

Should You Buy It

Yes, if you have a 42" or 46" MTD-family deck and your current belt guard is missing, bent, or rusted through. It’s a cheap, easy fix that prevents belt damage and keeps debris out of the pulley area. Not for decks outside that size range or non-MTD brands.
