Yeah AVB, I've got one of those out here in the garage somewhere, but there isn't a knife on the debris shield on my unit. I have a craftsman parts trimmer with an aluminum hub that you put two strands of line thru. I'll investigate it. Alternatively, I have a head out here somewhere that uses the swinging plastic blades. That would be the best route in the long run. (replaceable blades, albeit, if I could find replacements)
Hmmm, That's a different debris shield in the pic from Anto86 so, it might have a knife. I'll have to investigate.
I tried the Mac blade. It is 200mm, but it is 20mm arbor. The Stihl is 1" arbor. I'll have to buy one.
Would it not be feasible to use a 9" blade on this trimmer?
P.S. I overlooked that the IPL does show the drive shaft. Just a small section view...
