ZALANA 103-6393 103-6398 Lawn Mower Toothed Mulching Blades Replaces 103-6383 116-5174 96-749 Compatible with Exmark Lazer Z DS-Series E-Series Turf Tracer 60" Deck (6PCS)

What It Is

This is a six-pack of toothed mulching blades designed for 60-inch Exmark Lazer Z zero-turn mowers. The blades cut grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch deck and is an Exmark Lazer Z DS-Series, E-Series, or Turf Tracer. These blades replace OEM part numbers 103-6383, 103-6393, 103-6398, 116-5174, and 96-749. Measure your current blade length—these are 20.5 inches long with a 1-inch center hole and a 0.25-inch thickness. They will not fit 48-inch or 72-inch decks, nor non-Exmark brands without verifying spindle specs.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a torque wrench (set to 70-90 ft-lbs) and a blade removal tool. Always disconnect the spark plug first.
• Quality check: ZALANA is an aftermarket brand; reviews note good balance and sharpness out of the box. Inspect for warping before installing.
• Common gotcha: These are mulching blades, not standard lift blades. They produce finer clippings but may not eject grass as far in side-discharge mode. Do not mix with standard blades on the same spindle.
• Wear expectation: In sandy or rocky soil, expect faster dulling than OEM blades. Resharpen or replace after 25 hours of heavy use.

Should You Buy It

If you own a 60-inch Exmark Lazer Z and want an affordable mulching upgrade without paying OEM prices, this six-pack is a solid value. It’s ideal for operators who mow frequently and want to leave fine clippings on the lawn. Avoid if you need high-lift bagging blades or if your deck has non-standard spindle spacing.
