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.

Perfect for Teething Puppies and Adult Dogs and Keeps Them Busy
Color: Pacifier, Size: Small, Color: Pacifier, Size: Small
The Nylabone Puppy Pacifier Chew Toy has been a lifesaver during my puppy’s teething stage and AFTER. Quality: The material is sturdy yet gentle enough for developing puppy teeth. After weeks of daily use, it shows normal wear. The pacifier shape makes it easy for small mouths to grip and carry around. Effectiveness: It’s great for soothing sore gums and redirecting chewing behavior. I’ve noticed my puppy is calmer after chewing on it for a while. Helpfulness Tip: Supervise during chewing sessions and wash it occasionally with warm soapy water to keep it clean. If you have a small-breed puppy under 25 lbs, this toy is a safe, durable, and fun way to help with teething. Bought twice, they love these. Miniature dachshund and French bulldog

Nice chew toy
Color: Dinosaur, Size: Small
I have a small dog that loves chewing on these. It’s a bit pricey, but it helps keep her teeth clean, so I will pay this over her needing tooth extractions and a vet bill.

Not chew proof for little puppies
Color: Rings, Size: Small
Our first Chihuahua when she was a puppy loved chewing on this and pieces never came off. Our second Chihuahua I guess was a heavier tour and he was able to get pieces flaked off.

Great for teething puppy
Color: Pacifier, Size: Small
I was trying to find something very sturdy for our puppy that she could not bite pieces off of and this toy has been great. She loves it and it has held up very nicely. They are not soft so it is great for our teething pup. They are also the perfect size if you have a bigger pup like we do. She is a 4 month old pit mix. I would say they would be too big for a small breed puppy
