RCSBKT Bag of Five (5) Shear Bolt & Nut Kit for King Kutter Bush Hog Land Pride

What It Is

This is a five-pack of shear bolts and lock nuts designed to protect the driveline on rotary cutters and bush hogs. The bolts are intended to snap under excessive load, preventing damage to the gearbox or PTO shaft on King Kutter, Bush Hog, and Land Pride models.

Fitment & Compatibility

Before buying, verify three things:

• Bolt dimensions: These are typically 5/16" x 2-1/4" (check your manual—some older models use 1/4" or 3/8" bolts).
• Grade: These are Grade 2 (soft) shear bolts—do not substitute with hardened bolts, or you risk gearbox damage.
• Deck size: Commonly fits 4–6 ft rotary cutters. Will not fit zero-turn mower decks or push mowers.
• OEM cross-reference: Compatible with King Kutter (part # KK-SB), Bush Hog (part # 100402), and Land Pride (part # 318-033P). If your model uses a different length or thread pitch, these won’t work.

Key Things to Know

• Grade is critical: These are intentionally soft to shear first. Using a higher-grade bolt (e.g., Grade 5 or 8) can transfer impact to your gearbox or PTO shaft, causing expensive damage.
• Installation is simple: No special tools needed—just a wrench or socket. Torque is not critical; tighten snugly. The nut is a lock nut, so no thread locker required.
• Common gotcha: If the bolt shears, always replace both the bolt and the nut. Reusing the nut may cause it to loosen or fail to hold torque.
• Five-pack value: At $33.99, this is cheaper per bolt than most OEM singles (often $8–12 each). Good to keep a spare set in your tool box.

Should You Buy It

Buy this if you own a King Kutter, Bush Hog, or Land Pride rotary cutter and want a cost-effective way to keep spare shear bolts on hand. It’s a no-brainer for anyone who mows rough terrain or hits hidden obstacles regularly. Skip it if your machine uses metric bolts, a different length, or a slip-clutch instead of a shear bolt system.
