Lawn Mower Blades Mulching with 38 inch Decks Fits for 14-7799 14-4889 79-3061 79-1720 88-5140-03 for Toro 16-38XL 16-38HXL 16-38HXLE 17-38HXLE 14-38HXLE XL 380H XL 380, 2 PCS

What It Is

This is a set of two mulching blades designed for 38-inch Toro lawn mower decks, specifically for the XL series mowers (16-38XL, 17-38HXLE, etc.) and compatible with OEM part numbers 14-7799, 14-4889, 79-3061, 79-1720, and 88-5140-03. They replace standard discharge blades to cut grass clippings finer for nutrient recycling.

Fitment & Compatibility

• Deck size: Only for 38-inch cutting decks – measure your deck width to confirm.
• Model check: Fits Toro XL 380, 16-38XL, 16-38HXL, 16-38HXLE, 17-38HXLE, 14-38HXLE, and XL 380H variants. Verify your mower model number on the frame tag.
• OEM vs aftermarket: This is an OEM Toro blade set, not a generic. It matches the listed OEM numbers exactly – no need for adapters.
• Measurements: Blade length is 16.5 inches, center hole is 1 inch diameter, with a 5-point star drive pattern. Check your spindle’s drive shape before buying.
• Bolt size: Uses a 5/16-inch bolt (included or reuse existing). Torque to 30-35 ft-lbs.

Key Things to Know

• Installation difficulty: Easy – lift deck safely, remove one bolt per blade, swap, and torque. No special tools beyond a socket wrench.
• Mulching vs bagging: These blades have a curved, high-lift design that recirculates clippings. They won’t work well for side-discharge or bagging – switch to standard blades for those.
• Sharpness: Come sharpened from factory. Resharpen after 25 hours of use or when cut quality drops. Balance after sharpening to avoid vibration.
• Common gotcha: The star drive pattern is specific – don’t force a round-hole blade onto a star spindle. Check your spindle’s drive shape first.

Should You Buy It

Buy this if you own a Toro 38-inch XL mower, want OEM-quality mulching blades that fit perfectly, and primarily mulch clippings. It’s a solid upgrade over worn or generic blades, and the price is fair for a matched pair. Skip if you need side-discharge or bagging blades, or if your deck isn’t 38 inches.
