ZT4200L 42'' Zero Turn Mower Blades Replacement for EGO ZT4204L/ZT4200L-FC/ZT4200S/ZT4200S-FC 42Inch Z6 Zero Turn Riding Mower - Steel High-Lift Dual Blades Replace AB4200D,2Pack

What It Is

This is a 2-pack of high-lift steel replacement blades designed specifically for EGO’s 42-inch Z6 zero-turn riding mowers (models ZT4204L, ZT4200L-FC, ZT4200S, ZT4200S-FC). They deliver aggressive suction for bagging or discharging grass, matching the OEM AB4200D blade design.

Fitment & Compatibility

• Deck size: 42 inches (uses two blades, not three).
• Fitment: Direct swap on EGO ZT4200L, ZT4200L-FC, ZT4200S, ZT4200S-FC, and Z6 42-inch models. Also replaces OEM part AB4200D.
• Measurements: Each blade is roughly 21 inches long, 2.5 inches wide, with a 5-point star center hole (0.75-inch center). Confirm your existing blade matches these dimensions.
• Not compatible with EGO 56V push mowers, 52-inch Z6 decks, or any non-EGO zero-turn.

Key Things to Know

• Installation: Simple bolt-on swap. Use a torque wrench to tighten the center bolt to 50–60 ft-lbs (check your manual). No adapters or spacers needed.
• Quality: High-lift design improves grass clipping discharge but increases power draw slightly—fine for EGO’s electric motors. Steel is heat-treated and coated to resist rust.
• Gotcha: These are not mulching blades. If you want fine clippings left on the lawn, look for a mulching set or baffle kit.
• Balance: Each blade is balanced out of the box, but always check with a balancer after sharpening or impact damage.

Should You Buy It

If you own a 42-inch EGO Z6 zero-turn and need a direct OEM-replacement blade for bagging or side-discharge, this 2-pack is a solid, affordable option. It’s identical to the factory AB4200D at a lower price. Skip it if you mulch or have a different deck size.
