Bush Hog Rotary Cutter Blades Replacement Fit for Mower King Skidsteer Kubota Caterpillar Bobcat Case CAT John Deere, Brush Hog Mower Blade, 4 Pcs

What It Is

This is a set of four replacement rotary cutter blades designed for heavy-duty brush hogging on skid-steer and compact tractor-mounted mowers. They are intended for use with brands like Bush Hog, Mower King, Kubota, Caterpillar, Bobcat, Case, CAT, and John Deere—primarily for clearing thick grass, weeds, and light brush.

Fitment & Compatibility

Before buying, verify these three measurements against your existing blade:

• Length: Center-to-center hole distance and overall length must match your deck.
• Center hole size: Typically 1” or 1-1/8” diameter—check yours with a caliper.
• Thickness and width: These blades are likely 1/4” to 3/8” thick; confirm your mower’s spindle clearance.

These are aftermarket blades, not OEM. They claim compatibility with a wide range of models, but there is no universal fit—cross-reference your mower’s model number (e.g., Bush Hog SQ72, Mower King 72”) with the seller’s fitment list. Deck size (60”, 72”, etc.) is a starting point, not a guarantee.

Key Things to Know

• Quality concerns: With a 3.4-star rating from only 2 reviews, expect variability in steel hardness and balance. They may wear faster or chip easier than OEM blades.
• Installation difficulty: Moderate. You’ll need a torque wrench (specs vary by spindle, typically 100-150 ft-lbs) and a blade puller if stuck. Always use thread locker on bolts.
• Common gotcha: “Fit for” lists are often optimistic. Measure your old blade’s bolt pattern and thickness precisely—return shipping on a 30-lb set of blades is expensive.
• Set of 4: Confirm your mower uses 4 blades (some use 2 or 3). Mismatch in count means wasted blades.

Should You Buy It

This is a budget-friendly option for owners of older or less common mowers who need a quick replacement and are comfortable with some fitment risk. If you have a high-use commercial mower or demand long blade life, skip this—spend more on OEM or a well-reviewed aftermarket brand with solid steel specs and better reviews.
