LOSTAR Tractor Mulch Cover Kit 46" with Blades for RZT LTX LX 1045 1046 SX XT1 XT2 ZT1

What It Is

The LOSTAR Tractor Mulch Cover Kit is a 46-inch complete set that replaces your mower’s side-discharge chute with a mulch cover and includes three mulching blades. It’s designed for Cub Cadet and similar tractors/zero-turns to convert from bagging or discharging to fine mulching, leaving clippings chopped and dropped.

Fitment & Compatibility

Before buying, confirm deck size is exactly 46 inches—measure your deck’s cutting width, not the tractor model alone. This kit is listed for Cub Cadet RZT, LTX, LX 1045, 1046, SX, XT1, XT2, and ZT1 series. Also fits many MTD, Troy-Bilt, and Craftsman models with a 46-inch deck and a 5-point star spindle pattern (common on these brands). Check your blade center hole shape—must be a 5-point star, not a round hole or oval. OEM equivalents include Cub Cadet 742-0671, 942-0671, and 742-0671A. Measure blade length (likely 18.5 inches) and thickness (0.25 inch typical). If your deck has a discharge chute interlock, verify the mulch cover clears it.

Key Things to Know

• Quality: Blades are heat-treated steel, but reviews are limited (3 ratings). Some users report they are slightly lighter than OEM, but still durable for residential use.
• Installation: Straightforward—remove old blades and chute, bolt on the mulch cover, and install new blades. Torque blades to 40-50 ft-lbs. No special tools needed.
• Gotchas: The mulch cover may not seal perfectly on all decks—check for gaps that let clippings escape. Also, mulching blades require sharper grass (not wet or overgrown) for best results.
• Fitment caveat: Double-check your deck’s spindle bolt size (usually 5/8-inch or 3/4-inch). This kit uses standard 5/8-inch bolts; if your deck uses a different size, you’ll need adapters.

Should You Buy It

If you own a Cub Cadet or compatible 46-inch deck tractor and want an affordable mulching conversion without buying separate blades and a cover, this kit is a decent value at $45. It’s best for residential users with average-sized lawns who prefer mulching over bagging. For heavy-duty commercial use or perfect OEM fit, consider spending more on a brand-name kit.
