TRUPER HP-2 Serrated Grass Hooks 20" (51cm) 13" (33cm)

What It Is

The TRUPER HP-2 is a set of two serrated grass hooks (blades) designed for string trimmers and brush cutters. The 20" (51cm) and 13" (33cm) lengths suit heavy-duty clearing of thick grass, weeds, and light brush, not for standard lawn edging or mowing.

Fitment & Compatibility

Before buying, verify three things:

• Deck/Head Size: These hooks are for trimmer heads that accept blade attachments (usually with a central hole and two mounting holes). They are not universal—check if your trimmer has a blade-ready head.
• Mounting Pattern: The HP-2 uses a standard 25.4mm (1") center hole and two outer holes spaced 44.5mm apart. If your trimmer uses a different pattern (e.g., 20mm center or single-bolt), these won’t fit.
• Brand/Model: TRUPER parts often fit their own trimmers (e.g., TPH-26, TPH-43) and some generic Chinese or OEM units. They are aftermarket—no guarantee for major brands like Stihl, Husqvarna, or Echo. Measure your existing blade’s hole pattern precisely.

Key Things to Know

• Quality: Serrated edges cut well but dull faster on rocky or dirty terrain. Expect to sharpen or replace more often than standard trimmer line.
• Installation: Easy if your trimmer head has a blade adapter. You’ll need a wrench and possibly a locking pin. Always wear gloves—edges are sharp.
• Safety: These blades throw debris violently. Always use a guard and wear eye/leg protection. Never use on a trimmer rated for line only.
• Gotcha: The 20" blade is very long—only fits trimmers with a large cutting swath and enough power (35cc+). On a small electric trimmer, it can bog down or damage the head.

Should You Buy It

Buy these if you need a budget-friendly, serious clearing blade for a compatible TRUPER or generic trimmer and you’re okay with frequent sharpening. Skip them if you have a major-brand trimmer with a non-standard mount, or if you only need light trimming—standard line is safer and simpler.
