Modify residential grade Stihl line trimmer to accept commercial attachments.

If your like me, and have acquired or bought a residential model of a Stihl line trimmer only to find out later that it can’t run all Stihls implements because it’s a “residential” machine. Then this might be the video for you. To explain, the residential grade line trimmers have a flexible spun wire drive shaft that will bind and wrap inside the 1” tube when under high torque, much like when you use a broom attachment. Commercial trimmers have a solid shaft that takes care of that problem. My situation: Borrowed my fathers broom attachment and ran it on my trimmer. Fit great, with plenty of power to drive it. However it made nasty noises during use from the wire drive shaft in the tube. Calling Stihl tech support I was informed that yes it will fit and operate but it’s not rated for use because of the wire shaft. Problems from continuing to use that wire shaft trimmer will include breakage of the wire shaft, and damage to the tube liner. My Solution: Having already disassembled the trimmer a few times to repair it when I first bought it, I learned how the tube was secured in the handle of the power head, and figured looking at other models they are likely fit the same or similar. Took a shot in the dark and found an approved compatible model off the Power broom spec sheet, then went to eBay and found a used but complete tube assembly (tube,liner,shaft) for sale for cheap (~$40). New they go for $$$. Took apart my machine and went to work. Saw that while all models mount similarly, they are not exactly the same. The new assembly was slightly longer, and the locator holes were in different locations. No problem really. Just drilled a new tube locator hole to match the old shaft and then the tube fit great. Next issue was making the shaft fit since the “stick out” is also different, likely because the clutch spline sits different against the shafts. I measured the old one and cut the new one to maintain the same stick out, then had to grind the square drive farther up the shaft as shortening it still didn’t give enough usable spline to seat the whipper chord head or other attachment deep enough on the tube to seat it to the bottom. After that I just fit my trimmer end back on and started it up for a quick test. So far so good! We will see how it holds up. Worst case it breaks and I’m out a used tube assembly, and I can revert it back and sell it for a used commercial one. But I don’t see that being the case. I’ll let you know if there’s any changes or updates!
