2-Pack 783-06424A-0637 Spindle Pulley Belt Guard Cover Compatible with MTD Cut 42" 46" Deck Tractors, Fits Model 24728901 24728911 247289010, Replaces 783-06424A

What It Is

This is a 2-pack of spindle pulley belt guard covers designed for MTD-branded lawn tractors with 42-inch or 46-inch cutting decks. They protect the spindle pulley and belt from debris, reducing wear and preventing belt slip or damage during mowing.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 42" or 46" (measure if unsure). These fit MTD models 24728901, 24728911, and 247289010 specifically. They replace OEM part number 783-06424A. Check your original guard’s mounting hole spacing and overall shape—aftermarket versions may have slight dimensional differences. If your tractor uses a different spindle assembly or deck design (e.g., 50" or 54" decks), these will not fit. Verify the guard’s bolt pattern matches your existing mount points.

Key Things to Know

• Material quality: These are stamped steel, not plastic. They hold up well but can rust if paint chips—apply touch-up paint if needed.
• Installation difficulty: Easy—typically 2 bolts per guard. Use a socket wrench and check for rusted fasteners; penetrating oil helps.
• Common gotcha: The guards may not align perfectly with older decks due to minor manufacturing tolerances. You might need to enlarge bolt holes slightly with a round file.
• Set of two: You get two guards, so if you only need one, the extra is a spare or can be shared with another compatible tractor.

Should You Buy It

If you own an MTD 42" or 46" deck tractor from the listed model numbers and your OEM guard is broken or missing, this is a cost-effective, direct replacement. It’s not for universal use—strictly for those specific decks. For $15.89, it’s a solid value if fitment checks out.
