3-Pack Standard Lift 21" Mower Blades Replacement for John Deere 60" Deck Z730M Z735E Z735M Z720E Z740R Z760R Zero Turns, Fits OEM UC14208 M163983, 15/16" Center Circle Hole

What It Is

This is a 3-pack of 21-inch standard-lift mower blades designed for John Deere ZTrak 60-inch zero-turn mowers. They replace OEM part numbers UC14208 and M163983, intended for cutting grass on residential or light commercial lawns.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Your mower must have a 60-inch deck (7-gauge stamped, typically). These blades are 21 inches long and only fit 60" decks.
• Model series: Confirmed compatible with John Deere Z720E, Z730M, Z735E, Z735M, Z740R, Z760R. Not for older or non-ZTrak models.
• Center hole: These have a 15/16-inch center circle hole. Measure your existing blade’s center hole—if it’s a star or different size, these won’t fit.
• OEM cross-reference: Direct replacement for OEM UC14208 and M163983. If your blade has a different OEM number, measure length and hole size.

Key Things to Know

• Quality concern: With a 3.6 rating from only 4 reviews, expect mixed feedback on durability and balance. Standard-lift blades are fine for flat lawns but won’t handle heavy mulching or high-lift discharge.
• Installation: Simple swap with a socket wrench. Torque bolts to 70-90 ft-lbs. No special tools needed, but check blade balance before mounting.
• Common gotcha: These are not universal. Many 60" decks use 20.5" or 18" blades—double-check your blade length with a tape measure.
• Price point: At $45.99 for a 3-pack, it’s cheaper than OEM but may wear faster or chip on rocky terrain.

Should You Buy It

Buy these if you have a compatible John Deere ZTrak 60" deck, need a budget-friendly replacement for basic grass cutting, and don’t mind slightly lower durability than OEM. Skip them if you require high-lift performance, mulching, or heavy commercial use—look for a premium aftermarket or genuine John Deere blade instead.
