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.

Cushioned, comfortable, stylish and a rubber sole!
Size: 10, Color: Brown
These shoes check multiple boxes for me, comfortable, cushioned, rubber sole and stylish. As my feet grow old and worn out, I'm on a constant search for comfortable, cushioned shoes that are suitable for work and dressier occasions. I have tried many expensive shoes that look great but either lack cushioning, arch support and or comfort. One of the nice things is these shoes have a rubber sole, where most cushioned shoes have the foam soles which are great, but they tend to lack grip particularly when its damp/wet. They have average arch support, but the insole is removable and I put my own cushioned arch support. Love these!

OG Style
I am a big fan of Bruno Marc shoes. Over the years they have provided comfortable and affordable boots and shoes. These blue, tan and white soled dress sneakers are no exception. They have a nice finished look that makes them both causal and dressy. The lightweight style is still warm enough for colder mid-west winters. The box of the toes is wide and comfortable. The insole is well padded and a pleasure to wear. This is another fine pair of shoes to add to my collection and yours.

WIDE Dress Shoes With SUPPORT
Size: 10.5, Color: Brown
I've seen dress shoes and worn dress shoes before, but these are simply the best dress shoes I've ever worn my entire life. 99% of dress shoes have the same problem, they have the thinnest little soles that offer no support. BRUNO MARC HAS SOLVED THE PROBLEM. These dress shoes not only support wide feet like mine who historically have had and still have little support in the market, but Bruno Marc has wide options that fit perfectly, and the support with the thick foam sole is so needed and awesome. I had a pleasant surprise putting these things on and there being some tactile grip enhancers inside the shoe so you can feel the shoes better and get a little tickle / massage while you're at it. These things are dripping with style, easy to wear, and while they might look firm on the outside, on the inside the shoe just has such a nice flexibility and foamy feel, the top where the top of your feet feel the roof of the shoe, it has such perfect ooey gooey support I can't believe it. The outside sole also has this neat tactile feel. The durability looks good and feels good for now.
