MightyRugged GX26401 John Deere Traction Drive Belt Replacement - Heavy-Duty, Durable, Aramid Cord Mower Traction Drive Belt for Z200 and Z300 Series Mower - Z335E

What It Is

The MightyRugged GX26401 is a heavy-duty traction drive belt replacement for John Deere Z200 and Z300 series zero-turn mowers. It transfers power from the engine to the drive pulleys, propelling the mower forward and backward—critical for movement, not the cutting deck.

Fitment & Compatibility

• Fits: John Deere Z200 series (Z225, Z235, Z245) and Z300 series (Z335E, Z345R, Z355R, Z375R) zero-turn mowers.
• OEM Cross-Reference: Replaces John Deere part GX20072 and GX26401. Confirm your mower’s OEM part number before ordering.
• Measurements: Belt length is approximately 93.5 inches, width 0.5 inches. Measure your old belt’s length and width to verify—variations exist between mower models.
• Check: Your mower’s serial number or deck size (typically 42–54 inches) doesn’t affect fitment for this traction belt, but ensure you’re not confusing it with a deck drive belt.

Key Things to Know

• Quality: Aramid cord construction offers higher tensile strength and heat resistance than standard rubber belts—good for heavy use or rough terrain.
• Installation Difficulty: Moderate. You’ll need to remove the mower deck, release belt tension via the idler pulley, and route the belt around the drive pulleys. A diagram helps; take a photo before removal.
• Common Gotcha: This belt is for traction drive only—not for the cutting deck. Double-check that you’re replacing the correct belt.
• Break-In: Expect a slight stretch during the first hour of use; re-tension if needed per your mower’s manual.

Should You Buy It

If you own a compatible Z200 or Z300 series John Deere and need a reliable, heavy-duty replacement for the traction drive belt, this is a solid, cost-effective option. It’s best for DIYers comfortable with basic mower maintenance and those who want a step up from OEM without paying dealer prices. Not for casual users who rarely mow—standard belts work fine for light duty.
