I use the T55X trimmer head routinely with .155 line around fence rows on heavy course weeds and seedling trees. I have even loaded it with .170 line, but I can't tell much difference between the two sizes (.155 & .170) when cutting. That said the .170 is much harder to load on the spool. SLE delivered without delay and had competitive pricing. Always a pleasure doing business with them. Highly recommended.
Item shipped promptly and at a good price. Shipping is always somewhat high for these items, but this was within reason.
Works great on 345FR. Built heavier and larger than stock T45X. The only bump head I can find that handles 0.155" line. Faster and less waste than fixed heads.
A very good investment. Quality. I bought two.
The T55X trimmer head installs easily on my 355FX clearing saw. It's a well designed/made product that works as advertised. Extremely competitive pricing from SLE Equipment contributed to making this a very satisfying purchase.
