110-6837-03 Mower Blades Fit for Toro TimeCutter 50" Deck SS5000, 115-5059-03 High Lift Blades Compatible with Toro Z5000 SS5060 50" Zero Turn Mower Riding Tractor, Replace 112-9759-03, 3 Pack

What It Is

This is a 3-pack of high-lift replacement blades (OEM part 110-6837-03, also cross-referenced as 115-5059-03) designed for Toro TimeCutter SS5000 and Z5000 SS5060 zero-turn mowers with a 50-inch cutting deck. High-lift blades create stronger airflow to lift grass for a cleaner cut and better bagging performance.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 50-inch Toro decks. Measure your deck width to confirm.
• Model compatibility: Works with Toro TimeCutter SS5000, Z5000 SS5060, and any other Toro zero-turn that uses OEM part numbers 110-6837-03, 115-5059-03, or 112-9759-03. Check your owner’s manual or current blade part number.
• Physical dimensions: Each blade is approximately 20.5 inches long, 2.5 inches wide, with a 5/8-inch center hole and 7/16-inch offset. Measure your old blade to confirm length, hole size, and offset pattern.
• Aftermarket vs. OEM: These are OEM Toro blades, not generic aftermarket. That means exact fit, but higher price than no-name alternatives.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, a block of wood to jam the blade, and basic mechanical comfort. Torque blades to 70-90 ft-lbs.
• High lift = more power draw: These blades require more engine power. If your mower struggles on thick grass, you may need to slow down or cut less frequently.
• Sharpening: Blades are pre-sharpened but will dull after 10-15 hours of use. Sharpen or replace in sets to maintain balance.
• Balance check: Always balance new blades before installing. An unbalanced blade causes vibration, poor cut quality, and bearing wear. Use a simple blade balancer.

Should You Buy It

Buy these if you own a Toro TimeCutter SS5000 or Z5000 SS5060 with a 50-inch deck and need OEM-quality high-lift blades for bagging or cutting tall, thick grass. They’re also a direct match for anyone replacing 112-9759-03 blades. Skip them if you have a different deck size, a non-Toro mower, or if you mow very short, dry grass where standard lift blades suffice.
