XHT 3 REPL HD USA Blades Compatible with John Deere TCU30317 HIGH Lift 54" Decks 737 757 Z710A

What It Is

This is a set of three high-lift lawn mower blades designed for 54-inch John Deere decks. High-lift blades create stronger airflow to eject clippings into a bagger or out a side discharge, making them ideal for mulching or collecting leaves.

Fitment & Compatibility

Before buying, confirm your mower has a 54-inch deck and uses OEM part number TCU30317. These XHT blades fit John Deere models including the 737, 757, and Z710A zero-turn mowers. Measure your existing blades: length should be 18 inches, width 2.5 inches, and center hole diameter 1 inch. These are aftermarket replacements, not OEM, so verify your spindle bolt pattern matches. If you have a different deck size (e.g., 48-inch or 60-inch), these will not fit.

Key Things to Know

• High-lift design improves bagging performance but increases engine load and may reduce run time per tank.
• Installation difficulty is low if you have a socket set and can safely lift the mower. Use a torque wrench to tighten bolts to 70-90 ft-lbs.
• Balance is critical – these blades are pre-balanced, but check with a blade balancer after sharpening.
• Common gotcha: ensure the blade orientation matches the deck’s air flow direction; the curved edge should face upward toward the deck.

Should You Buy It

Yes, if you need reliable high-lift blades for a 54-inch John Deere ZT model and want a cost-effective alternative to OEM. Avoid if your mower is a low-horsepower unit or you primarily mulch in dry conditions, as the extra lift can cause scalping on uneven terrain.
