3PK 32" & 48" Oregon 596-310 Gator Mulching Mower Blades for Bobcat 112111-01 & Ferris 1520843, 20843, 5020843, 1520843S

What It Is

This is a set of three 32-inch and 48-inch Oregon Gator mulching blades (model 596-310) designed for zero-turn mowers like Bobcat and Ferris. They replace OEM parts 112111-01, 1520843, 20843, 5020843, and 1520843S, giving you fine clippings for better lawn nutrient recycling.

Fitment & Compatibility

• Deck size: Fits 32-inch and 48-inch cutting decks only. Measure your deck width before ordering.
• Brand/model: Direct fit for Bobcat (e.g., 112111-01) and Ferris (1520843, 20843, 5020843, 1520843S) zero-turn mowers. Not for walk-behinds or other brands.
• OEM vs aftermarket: Aftermarket replacement; matches OEM specs but uses Oregon’s Gator blade design with serrated teeth.
• Measurements: Each blade is 16.25 inches long, 2.5 inches wide, with a 0.203-inch thickness and a 1-inch center hole. Verify your spindle pattern matches before buying.

Key Things to Know

• Quality: Oregon Gator blades are well-regarded for durability and mulching performance; serrated edges stay sharp longer than standard blades.
• Installation: Moderate difficulty—requires jacking the mower and removing spindle bolts. Use a torque wrench; spec is typically 70-90 ft-lbs.
• Gotcha: These are mulching blades, not for bagging or side-discharge. They produce finer clippings but can clog in wet, tall grass.
• Common issue: Check for bent spindles or worn blade carriers before installing—old damage will ruin new blades quickly.

Should You Buy It

If you own a compatible Bobcat or Ferris zero-turn with a 32- or 48-inch deck and want better mulching than OEM blades, this set is a solid, affordable upgrade. Skip it if you need bagging or side-discharge performance, or if your deck is a different size.
