511010601 / PT104 Trimmer Head for Redmax String Trimmers

Key Features

  • Heavy-Duty Bump-Feed Mechanism: Designed for commercial-grade durability, the PT104 "Plus" style head allows for rapid line advancement with a simple tap on the ground during full-throttle operation.
  • High-Capacity Spool: Accommodates up to 20 feet of 0.095" diameter line, significantly reducing downtime spent reloading during large landscaping jobs.
  • Reinforced Eyelets: Features high-grade metal alloy line exits that resist heat buildup and friction, preventing the trimmer line from "welding" to the head during heavy use.
  • Split-Spool Design: Engineered with an internal divider to prevent line tangling and "overlapping," ensuring a smooth, consistent feed every time the head is bumped.
  • Impact-Resistant Polymer: Manufactured from a specialized glass-filled nylon composite to withstand high-velocity impacts with rocks, curbs, and fence posts.

Compatibility & Fitment

This trimmer head is the standard "professional choice" for Redmax and Husqvarna-based straight shaft trimmers. Key compatible models include:

  • Redmax BC Series: BC250, BC225, BC2300, BC2600.
  • Redmax BCZ Series: BCZ2400S, BCZ2401S, BCZ2460S, BCZ2460TS, BCZ2600S, BCZ2601S, BCZ2660TS, BCZ3060TS.
  • Redmax TR Series: TR2300S, TR2301S, TR2350S.
  • Husqvarna: Fits many 200 and 300 series straight shaft trimmers (e.g., 223L, 323L, 326L) utilizing the M10 x 1.25 LHF (Left Hand Female) arbor thread.

When to Replace

  • Worn-Through Bump Knob: The red center knob has ground down to the point where the internal spring is exposed or it no longer triggers the line release.
  • Cracked Housing: Visible stress fractures in the black outer shell, which can lead to the head shattering at high RPMs.
  • Eyelet Failure: The metal eyelets have fallen out or are deeply grooved, causing the line to snap off inside the head frequently.
  • Internal Spool Jamming: The plastic "teeth" inside the head that lock the spool have rounded off, causing the head to dump all the line at once.
  • Excessive Vibration: The head has become unbalanced due to uneven wear, putting unnecessary stress on the trimmer's gear head and shaft.

Installation Tips

  • Left-Hand Threads: Remember, this head is Left-Hand Threaded. To tighten it onto the trimmer, you must turn it Counter-Clockwise.
  • Lock the Gear Head: Use a small screwdriver or the factory locking pin to hold the gear head shaft stationary while you spin the old head off and the new one on.
  • Spool Direction: When reloading line, follow the arrows molded into the spool. Loading the line in the wrong direction will prevent the bump-feed mechanism from working.
  • Soak Your Line: Professional tip: soak your trimmer line in a bucket of water for 24 hours before loading. This keeps the nylon flexible and prevents it from becoming brittle and snapping at the eyelet.
  • Clean the Spring: Every time you reload the line, shake out any dirt or grass trapped around the internal spring to ensure the "bump" action stays smooth.

Necessary for travel
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Purple
This is really cute and looks classy. Quality is very nice. The only thing is the hooks for the necklaces didn’t keep them on, but everything else about this is a must for traveling and not losing or tangling up your jewelry.

LOVE IT!
Size: Large (8.2"W*4.2"D*2.4"H), Color: Beige
I love it. It’s very pretty and simple, in a good way. I plan to use it for all my jewelry and not just for travel. I like that it has a lot of hooks for necklaces and plenty of space for earring and rings. The fabric inside and out seem to be good quality. It’s well made and zips easily. The structure is sturdy as well. The color (white) is just as depicted. I think I got the larger size but it doesn’t feel bulky at all. I like that it comes with an extra pouch for bulkier items. It’s one of the best jewelry boxes I’ve had!

Nice little travel solution for jewelry
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Pink
Cute travel box for my jewelry. The necklace hangers aren’t all that snug, causing my necklaces to fall and tangle some. But otherwise, works as expected.
