Parts Camp GX26422 John Deere Mower Deck Belt Replaces John Deere 48 Inch Z355E Z355R Z365R ZTrak, JohnDeere 54 Inch Z325E Z375R Z330M Z330R Zero Turn Mowers 1/2" x 145.65" Aramid Belt

What It Is

This is a replacement mower deck belt (Part # GX26422) designed to drive the blades on John Deere 48-inch and 54-inch ZTrak zero-turn mowers. It’s a 1/2” wide, 145.65” long aramid-reinforced belt for residential/commercial mowing.

Fitment & Compatibility

Check these three things before buying:

• Deck size & model: Fits John Deere 48” decks on Z355E, Z355R, Z365R; and 54” decks on Z325E, Z375R, Z330M, Z330R. Will not fit other deck sizes or non-ZTrak models.
• OEM vs aftermarket: This is an aftermarket replacement for OEM John Deere GX26422. Verify your existing belt part number—it must be GX26422 (not GX20072 or other variants).
• Measurements: Belt is 1/2” wide x 145.65” (approx. 145-5/8”). Measure your old belt’s length and width if unsure—a 1/2” difference can cause slipping or poor engagement.

Key Things to Know

• Aramid construction offers better heat resistance and durability than standard rubber belts, but it’s stiffer—may require more force to install.
• Installation difficulty: Moderate. You’ll need to remove the deck or use a belt tensioner tool. Expect 20–40 minutes if you’ve done it before; longer for first-timers.
• Common gotcha: The belt routing diagram on John Deere decks varies by model year. Check your owner’s manual or snap a photo of the old belt path before removal.
• Price vs OEM: At ~$25, it’s roughly half the cost of a John Deere branded belt. Reviews are limited (5 ratings) but positive.

Should You Buy It

This belt is a solid budget-friendly choice for owners of the listed John Deere ZTrak models who want aramid durability without paying OEM markup. If you need exact fitment and have a newer model (post-2020), confirm routing compatibility first—otherwise, it’s a reliable drop-in replacement for most 48” and 54” decks.
