Greenworks 42-inch Replacement Blades Kit for Tractors & Zero-Turns — 2-in-1 Mulching/Side-Discharge, Heavy-Gauge Steel

These Greenworks 42-inch full replacement blades swap into compatible tractors and zero-turn mowers to deliver both side-discharge and mulching performance with durable steel construction.

Replace worn or damaged cutting blades with a direct-fit Greenworks 42" blade kit engineered for reliable, all-season lawn care. The kit includes heavy-gauge steel blades shaped for two operating modes: a side-discharge profile for fast clipping ejection and a mulching profile that chops clippings finely to return nutrients to the turf. Each blade is formed and balanced to reduce vibration, maintain sharpness longer, and restore the clean-cut appearance your mower produced when new.

How do these blades switch between mulching and side discharge?

The blades are designed with a 2-in-1 geometry that supports both mulching and side-discharge mowing without additional adapters. Orientation and mounting on the mower deck, together with your deck’s baffles, determine whether clippings are expelled or recirculated and re-cut into tiny pieces. You can change mowing style quickly by following the mower’s recommended blade position.

• 2-in-1 blade profile supports both cut-and-throw and mulching modes
• Install blades in the specified orientation for intended mode
• No extra hardware required beyond standard mounting bolts

What makes these blades durable and precise?

Manufactured from high-quality steel, the Greenworks replacement blades resist bending and wear during regular mowing. The edge geometry and balance help maintain a sharper cutting surface longer, which improves the consistency of the cut and reduces stress on your mower. Properly installed and periodically sharpened, they offer dependable performance through seasons of use.

• Heavy-gauge steel construction for impact resistance
• Balanced design to minimize vibration and wear on spindles
• Edge shape optimized for cleaner cuts that promote even turf growth

Will these blades fit my mower and how easy is installation?

This kit is made to fit Greenworks 42-inch zero-turn mowers and tractors that accept standard 42" deck blades. Installation follows the usual blade-replacement steps: raise the deck, secure with safety blocks, remove old blades, and torque new blades to the manufacturer’s specification. If you follow your mower manual, the swap can be completed with basic hand tools in minutes.

• Compatible with Greenworks 42" zero-turns and tractors
• Standard bolt-on replacement — no custom mods required
• Follow mower manual torque specs and safety precautions
