Implement 7' & 8' Heavy Blade Pair, 1/2" X 3 1/2" X 33 1/2"

What It Is

This is a pair of heavy-duty, universal replacement blades (1/2" thick, 3 1/2" wide, 33 1/2" long) designed for 7’ and 8’ finish or rough-cut mower decks, commonly used on compact tractors, zero-turn mowers, or pull-behind mowers in commercial or large residential settings.

Fitment & Compatibility

Before buying, measure your existing blade length (hole center to tip), center hole size (typically 1/2" or 5/8"), and overall width. These blades are 33 1/2" long with a 1/2" center hole—common on brands like Bush Hog, Land Pride, Woods, and Rhino, but not universal. Check your deck’s blade bolt pattern (usually a 5/8" or 3/4" hex bolt). These are aftermarket; they may not fit OEM-only decks with proprietary mounting. Verify your deck’s spindle clearance for the 1/2" thickness—some older spindles may require a thinner (3/8") blade.

Key Things to Know

• Build quality: Heavy 1/2" thickness resists bending and lasts longer than standard 3/8" blades on rocky or rough terrain, but adds weight that may strain smaller spindles.
• Installation: Easy if you have a torque wrench and can lift the deck safely. Use anti-seize on bolts; torque to manufacturer spec (usually 70-100 ft-lbs). No blade-tip removal needed.
• Common gotcha: These are NOT universal. Measure twice—33 1/2" blades are less common than 30" or 36". Also, confirm your deck takes a single center hole (not a multi-hole pattern).
• Balance: Aftermarket blades may need balancing. Use a blade balancer to avoid vibration and spindle wear.

Should You Buy It

Buy these if you need a tough, affordable replacement for a 7’ or 8’ mower deck with a 1/2" center hole and you’re okay with aftermarket fitment checks. They’re ideal for rough conditions where stock blades dull or break quickly. Skip if you want OEM-only parts or have a deck with a non-standard spindle bolt size.
