Grasscool 942-04385 TB30 Mower Blade for Troy Bilt 30 inch TR30 TB30R Cub Cade CC30 CC30H Craftsman R1000 RER1000 R1500 30'' Deck Mower Replace for 742-04385

What It Is

The Grasscool 942-04385 TB30 is a 30-inch replacement mower blade designed for select Troy-Bilt, Cub Cadet, and Craftsman riding mowers with a 30-inch stamped deck. It’s a direct aftermarket replacement for OEM part 742-04385, intended for cutting grass on medium to large lawns.

Fitment & Compatibility

Before buying, confirm your mower has a 30-inch deck (not 42 or 46). This blade fits specific models: Troy-Bilt TB30, TB30R, TR30; Cub Cadet CC30, CC30H; Craftsman R1000, RER1000, R1500. Also fits some Husqvarna and Poulan Pro 30-inch decks. Cross-check your OEM part number—this replaces 742-04385 (and 742-04386 for some variants). Measure your existing blade: this blade is 30 inches overall length, with a 1-inch center hole and 5-point star drive mounting pattern. If your spindle uses a 6-point star or round hole, it won’t fit.

Key Things to Know

• Quality: Grasscool blades are made from hardened steel, comparable to OEM. They’re not premium mulching blades but work well for standard bagging and side-discharge.
• Installation: Requires a socket and torque wrench (tighten to 70-90 ft-lbs). The blade is heavy—support it when removing the old one to avoid injury.
• Common gotcha: The blade is directional; the “this side down” decal must face the ground. Installing upside down will produce poor cut and vibration.
• Balance: Check blade balance after installation—Grasscool blades are usually balanced, but a quick spin test on a balancer prevents wobble.

Should You Buy It

If you own a Troy-Bilt, Cub Cadet, or Craftsman 30-inch deck rider and need an affordable, reliable replacement for OEM 742-04385, this is a solid pick. It’s not for mulching setups or decks over 30 inches, but for standard cutting and bagging, it’s a well-reviewed, budget-friendly choice that performs like the original.
