Terre Products, 3 Pack Mulching Lawn Mower Blades, 52 Inch Deck, Compatible with Ariens Promaster, Replacement for Ariens 00273100, Husqvarna 539100341, Scag 482878, 481707, 481711, Exmark 103-2508

What It Is

This is a 3-pack of aftermarket mulching blades designed for 52-inch commercial zero-turn mower decks. They replace OEM part numbers from Ariens, Husqvarna, Scag, and Exmark, and are intended for operators who want fine grass clipping mulching rather than side discharge or bagging.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 52 inches from blade tip to blade tip. These blades fit Ariens Promaster (e.g., 00273100), Husqvarna (539100341), Scag (482878, 481707, 481711), and Exmark (103-2508) models, but not all variants—check your owner’s manual for the specific OEM part number. The blades are aftermarket, not OEM, so verify center hole size (typically 1 inch or 5/8 inch) and overall length (must match your deck’s specifications). Measure your current blade’s length, width, and thickness to confirm compatibility.

Key Things to Know

• Quality: At $36.77 for a 3-pack, these are budget-friendly. Some users report slightly thinner steel than OEM, which may reduce lifespan on rocky or heavy-duty mowing.
• Installation: Straightforward if you have a socket wrench and blade removal tool. Use a torque wrench (typically 70–90 ft-lbs) and apply anti-seize to prevent rusted bolts.
• Mulching performance: The high-lift design helps recirculate clippings, but works best in dry grass. Wet or tall grass may still clump.
• Common gotcha: These blades are not universal—double-check your spindle bolt pattern (some Scag models use a different offset). Mismatched blades can cause vibration or deck damage.

Should You Buy It

If you own a compatible 52-inch commercial zero-turn and want an affordable mulching blade set for routine maintenance, this 3-pack is a solid value. However, if you mow heavy, wet grass or need maximum durability for daily commercial use, consider OEM blades for longer life.
