How do toothed blades affect cutting and turf health?

Toothed blades are designed to create a more aggressive slicing action, which can help with thicker grass, broken-in lawns, and certain mulching setups. They may lift and disperse clippings differently than straight-edged blades, so results depend on mower speed and deck settings. Proper sharpening and balance preserve turf appearance and reduce vibration.

• Toothed edge enhances cutting on dense or damp grass
• Can improve mulching when paired with suitable deck and rpm
• Requires correct sharpening angle to avoid tearing grass
• Balanced set reduces vibration and wear on spindles

What should I check before installing these replacement blades?

Before installation, verify exact OEM part numbers and the mower's deck serial range to confirm compatibility. Inspect spindle hardware, blade adapters and deck condition to ensure safe mounting. Use recommended torque specs and check blade balance after installation to avoid vibration and premature wear.

• Match OEM numbers 103-6397 / 116-5175 or their "-S" variants
• Confirm deck serial ranges for Turf Tracer and Front Runner decks
• Inspect and replace worn spindle hardware or adapters if needed
• Tighten blades to manufacturer torque and check balance
