42" 3-in-1 Kit for Troy-Bilt TB42/Super Bronco/Pony 42X, Craftsman T1300, Cub Cadet XT1-LT42 942-04308 Blades + 937-05066 951-12690 Air Filter Fuel Filter + 954-04060C Belt

What It Is

This is a bundled replacement kit for 42" cutting decks on Troy-Bilt, Craftsman, and Cub Cadet lawn tractors. It includes three mower blades, an air filter, a fuel filter, and a drive belt—everything needed for a full season tune-up on a single machine.

Fitment & Compatibility

Check these three things before buying:

• Deck size: Must be exactly 42 inches. Measure your deck from blade tip to blade tip.
• Model list: Fits Troy-Bilt TB42, Super Bronco 42X, Pony 42X; Craftsman T1300; Cub Cadet XT1-LT42. Confirm your model number on the tractor’s data tag (under seat or on frame).
• OEM vs aftermarket: This kit uses OEM part numbers (942-04308 blades, 937-05066 air filter, 951-12690 fuel filter, 954-04060C belt). If your machine uses different OEM numbers, cross-reference with your owner’s manual.

Key Things to Know

• Blade quality: 3-in-1 blades (mulch, bag, side-discharge) are medium-duty. Fine for residential use; not for heavy commercial or rocky terrain.
• Installation difficulty: Moderate. Changing the belt requires removing the deck or using a spring tool. Blades and filters are straightforward.
• Common gotcha: The belt (954-04060C) is a specific length—double-check your model’s belt routing diagram. Wrong routing can cause slipping or premature wear.
• Filter fit: The air filter fits a side-mount, foam-prefilter housing. If your tractor has a different air box style, it won’t work.

Should You Buy It

If you own one of the listed tractors and want a single-purchase tune-up with OEM-spec parts, this kit saves time and shipping costs. It’s right for homeowners doing annual maintenance—not for commercial operators needing heavy-duty blades or specialized filters.
