501421E 60635 Twenty Five Sickle Section Fits Ford/New Holland Sickle Mower 450 451 455

What It Is

The 501421E 60635 Twenty Five Sickle Section is a replacement cutting blade segment for Ford/New Holland sickle mowers (models 450, 451, 455). It’s used in hay or brush cutting where a reciprocating sickle bar shears vegetation against stationary guards.

Fitment & Compatibility

• Exact fit: Ford/New Holland 450, 451, and 455 series sickle mowers.
• OEM cross-reference: Replaces Ford/New Holland part numbers 501421E and 60635. Not a universal part—check your existing sickle section shape and hole pattern.
• Measure before buying: Verify section length (typically 3 inches) and bolt hole spacing (center-to-center, usually 1 inch). Count holes per section (two-hole design is common).
• Deck size irrelevant: This is for the sickle bar, not the mower deck. Confirm your mower’s bar uses individual sections, not a continuous blade.

Key Things to Know

• Quality: Aftermarket brand (Twenty), not OEM. At $81.99, it’s priced competitively but verify steel hardness—softer steel dulls faster in abrasive conditions.
• Installation: Moderate difficulty. Requires removing old sections with a punch and hammer, then riveting or bolting new ones. A sickle bar anvil and rivet tool are needed.
• Common gotcha: Sections are handed (left or right bevel). Ensure you buy the correct orientation for your bar’s cutting direction. Also, check for bent guards—replacing sections on bent guards wastes time.
• Reviews: Only 2 ratings (5.0 stars) – limited data. Consider this a gamble on consistency.

Should You Buy It

Buy this if you have a Ford/New Holland 450-455 series sickle mower and need a cost-effective replacement for worn sections. It’s a decent aftermarket option for occasional use, but if you mow heavy brush daily, spring for OEM sections for better durability. Double-check your section orientation and hole pattern before ordering to avoid returns.
