BlueStars GX26422 Mower Deck Belt - Compatible with John Deere Z355E Z375R Z325E Z355R Z330M Z330R Z365R ZTrak Zero Turn Mowers and More | Aramid Cord | 145.5" x 0.5"

What It Is

The BlueStars GX26422 is an aftermarket mower deck belt designed to transfer power from the engine pulley to the spindle blades on select John Deere ZTrak zero-turn mowers. It replaces OEM part GX26422 and fits 42-inch, 48-inch, and 54-inch decks commonly used on residential/commercial models like the Z355E, Z375R, Z325E, Z355R, Z330M, Z330R, Z365R, and others.

Fitment & Compatibility

Before purchasing, verify your mower’s model and deck size against the list below. Measure your old belt’s length (145.5 inches) and width (0.5 inches) to confirm—this belt will not fit decks requiring a different length or width. Check your owner’s manual or the belt routing diagram under the deck for exact OEM part number (GX26422). This belt is aftermarket, not OEM John Deere, so it may differ slightly in material or tension. Compatible models include Z355E, Z375R, Z325E, Z355R, Z330M, Z330R, Z365R, and other ZTrak units using the same belt spec. Not for older non-ZTrak or 60-inch decks.

Key Things to Know

• Aramid cord construction offers good durability and heat resistance for residential use, but may wear faster than Kevlar or OEM belts under heavy commercial duty.
• Installation is moderate difficulty—you’ll need to remove the deck, release belt tension (spring-loaded pulley), and route the belt per the diagram. A belt installation tool or wrench helps.
• Common gotchas: Check pulley condition (worn or rough pulleys shred belts quickly). Ensure belt is not twisted before engaging tensioner. Aftermarket belts sometimes run slightly looser; re-check tension after first 15 minutes of use.
• 4.4-star rating from 1,346 reviews suggests reliable performance for most homeowners, but a few report premature stretching or squeaking on high-hour decks.

Should You Buy It

If you own a compatible John Deere ZTrak zero-turn and need an affordable belt for seasonal residential mowing (not daily commercial use), the BlueStars GX26422 is a solid value at $21.99. It’s a practical alternative to OEM belts if you’re comfortable with moderate DIY installation and occasional belt adjustment. For heavy-duty or professional use, consider OEM or a premium aftermarket belt with Kevlar reinforcement.
