8TEN LawnRAZOR Blade for MTD Craftsman T140 Troy-Bilt Bronco TB46 Horse XP 46" 942-04290A 742-04290A (High Lift) 2 Pack

What It Is

This is a high-lift replacement blade set (2-pack) designed for 46-inch cutting decks on select MTD/Craftsman, Troy-Bilt, and Cub Cadet riding mowers. The raised wing profile increases airflow for superior grass clipping discharge, making it ideal for bagging or side-discharge in thick, tall grass.

Fitment & Compatibility

Check these before buying:

• Deck size: Must be a 46-inch deck (measure from blade tip to tip across the deck to confirm).
• OEM cross-reference: Replaces MTD 942-04290A, 742-04290A, and 942-04290. Fits models including Craftsman T140, Troy-Bilt Bronco TB46, and Horse XP 46.
• Blade measurements: 20.5 inches long, 2.5 inches wide, 0.25-inch thickness, with a 5-point star center hole (common MTD pattern).
• Deck type: Designed for side-discharge or bagging decks; not ideal for mulching decks (will leave clumps if used with a mulch plug).

Key Things to Know

• High-lift vs. standard: Creates strong suction for bagging but increases engine load and blade wear in dusty/dry conditions.
• Installation: Easy bolt-on with a 15/16-inch socket; torque to 40-50 ft-lbs. Mark blade orientation before removal.
• Quality: Heat-treated steel with a black powder coat; edge holds up well for 1-2 seasons on residential lawns, but may dull faster on sandy soil.
• Gotcha: If your deck has a spindle bolt with a 3/4-inch head, you’ll need a different blade (this uses a 5-point star center).

Should You Buy It

Buy this if you have a 46-inch MTD-platform mower and need a dependable, budget-friendly high-lift blade for bagging or side-discharge in thick grass—especially if you’re replacing worn OEM blades and want better lift without paying OEM markup. Skip it if you primarily mulch or have a sandy/dusty yard where high-lift blades wear out quickly.
