Holdly GX26422 Deck Belt 1/2x146, Mower Belt for John Deere 54 Inch Z325E Z375R Z330M Z330R, John Deere 48 Inch Z355E Z355R Z365R ZTrak Zero Turn Mower

What It Is

The Holdly GX26422 is an aftermarket replacement deck belt for select John Deere ZTrak zero-turn mowers. It drives the blades on 54-inch decks (Z325E, Z375R, Z330M, Z330R) and 48-inch decks (Z355E, Z355R, Z365R) — a direct replacement for OEM part GX26422.

Fitment & Compatibility

Before buying, verify your mower’s deck size (54” or 48”) and model number (e.g., Z325E, not just “Z325”). This belt is 1/2 inch wide x 146 inches long — measure your old belt or check your owner’s manual for the OEM GX26422 part number. It’s an aftermarket belt, so it will fit those specific John Deere ZTrak models but may differ slightly from OEM in material or stiffness. Double-check your deck’s belt routing diagram — routing errors cause premature wear or belt slip.

Key Things to Know

• Quality vs. OEM: Holdly belts are typically Kevlar-reinforced and cost 30–50% less than John Deere genuine parts, but some users report slightly shorter lifespan (especially in heavy grass or debris).
• Installation difficulty: Easy to moderate — you’ll need a wrench to release the idler pulley tension. No special tools required, but a belt routing diagram (online or in manual) is essential.
• Common gotcha: The belt may feel tight or slightly stiff when new. Run the mower for 5 minutes at low throttle to seat it; recheck tension after the first use.
• Check pulleys: Inspect all deck pulleys for wear, rust, or wobble before installing — a bad pulley will eat any belt fast.

Should You Buy It

If you want a budget-friendly replacement that works out of the box for common John Deere ZTrak models, this is a solid choice. It’s not the longest-lasting belt on the market, but for homeowners with average-sized lawns (under 2 acres) who don’t mow daily, the price-to-performance ratio is strong. Skip it if you need maximum durability for commercial use or prefer OEM parts for peace of mind.
