GELASKA 942-04308 Mower Blades with Blade Nuts Fits Cub Cadet 42 inch ZT1 42 XT1 LT42 Mower Blades, T110 LT2000 LTX1040 LTX1042 LTX1045 Replaces 942-04308A 942-04312 Blades Cub Cadet, 2 Pack High Lift

What It Is

This is a 2-pack of high-lift replacement blades (with blade nuts) for 42-inch Cub Cadet mower decks. High-lift blades create stronger upward airflow for better grass clipping discharge and bagging performance, making them ideal for thick or tall grass.

Fitment & Compatibility

Before buying, check:

• Deck size: Fits only 42-inch Cub Cadet decks (not 46” or 54”).
• Model numbers: Confirmed for ZT1 42, XT1 42, T110, LT2000, LTX1040, LTX1042, LTX1045. Also fits many LT series tractors from 2010 onward.
• OEM cross-reference: Replaces Cub Cadet OEM part numbers 942-04308, 942-04308A, and 942-04312.
• Measurements: Blade length is 20.5 inches, center hole diameter is 0.75 inches, and the oval hole is 0.625 x 0.375 inches. Verify these match your existing blade.
• Includes: Two blades and two blade nuts (5/16-24 thread). You may need fresh washers or a clutch removal tool if your deck uses a multi-piece spindle assembly.

Key Things to Know

• Installation difficulty: Easy for most DIYers. Use a torque wrench to tighten blade nuts to 70-90 ft-lbs. Never exceed 100 ft-lbs to avoid stripping.
• High-lift trade-off: Better bagging and discharge, but may reduce engine RPM slightly in very thick grass. Not ideal for mulching unless you swap to a mulching plug.
• Sharp out of box: Blades come pre-sharpened but not razor-edged. A quick touch-up with a file before first use improves cut quality.
• Avoid cross-threading: The included nuts are standard thread. Use anti-seize compound on the spindle threads to prevent rust-seizing.

Should You Buy It

Buy this if you have a 42-inch Cub Cadet lawn tractor (especially models listed above) and prioritize bagging performance or need a budget-friendly OEM-equivalent replacement. Skip it if you have a different deck size, want mulching blades, or prefer OEM Cub Cadet blades for warranty compliance.
