One New Bolt & Nut Kit Fits King Kutter, Land Pride, Rhino, Universal Products, Fits Woods L60-HD, SQ142, SQ148, SQ420, SQ48, SQ480, SQ60 Models Interchangeable with 15349, 68439, 802-264C, A-RCSBKT

What It Is

This is a replacement bolt and nut kit designed for heavy-duty rotary cutter blades on mid-size to large brush mowers and finishing mowers. It secures the blade to the spindle assembly, ensuring safe operation during high-torque cutting.

Fitment & Compatibility

Before buying, confirm your mower’s blade retention system uses a single bolt and nut (not a bolt with a separate lock washer or a shoulder bolt). This kit fits King Kutter, Land Pride, Rhino, and Woods models including L60-HD, SQ142, SQ148, SQ420, SQ48, SQ480, and SQ60. It’s listed as interchangeable with OEM part numbers 15349, 68439, 802-264C, and A-RCSBKT. Measure your existing bolt length (threaded portion and overall) and nut thread size (typically 5/8"-11 or 3/4"-10). The kit is aftermarket, so verify the bolt head shape (e.g., hex, square) matches your blade slot and spindle hole. Check that the nut is a lock-type (nylon insert or all-metal) — if your spindle requires a plain nut with a separate lock washer, this kit may not be suitable.

Key Things to Know

• Quality: Grade 5 or higher hardware is typical for this application; confirm the bolt is marked with a grade rating (e.g., three lines on the head). The kit is priced at $33.99, which is reasonable for a matched pair of heavy-duty fasteners.
• Installation difficulty: Easy — a socket wrench, torque wrench (recommended), and penetrating oil (if bolts are rusted) are all you need. Torque to manufacturer spec (usually 80-120 ft-lbs for 5/8" bolts).
• Common gotchas: The bolt may be too short if your blade stack includes a spacer or thick washer. The nut’s lock feature can wear out after one or two removals; consider replacing both pieces each time you change blades. If your spindle uses a left-hand thread, this kit likely won’t work (most are right-hand).
• Universal claim: “Universal Products” is vague — always measure thread pitch and bolt length against your original hardware before assuming fit.

Should You Buy It

Buy this kit if you need a direct replacement for a single bolt-and-nut setup on a common brush mower brand (King Kutter, Land Pride, Rhino, Woods) and you want a matched pair with lock-nut security. Skip it if your mower uses a shoulder bolt, a bolt with a separate lock washer, or a left-hand thread — in those cases, stick with OEM hardware or a kit specifically designed for your model.
