Vibration problem w/ Shindawa T2500 trimmer

[JohnTN47]

I have a Shindawa T2500 weed eater about 4 years old. I bought it for the 4-cycle feature, lower noise, lower emissions. It has developed a bad vibration. It certainly doesn't have handles that isolate the vibration from operator. Has anyone had this problem? How was it solved?

FWIW, I don't have that model but I have the Ryobi 825R 4-stroke. The straight shaft attachment needs a new spool head and I have noticed a great deal of increased vibration, my left hands swells a little. I removed the straight shaft and installed my curved shaft from my 2-stroke powerhead and the vibration practically went away.

Sounds like more a balance issue in the spool...can you switch attachments or is it a fixed trimmer?

If the vibration is coming through the shaft, I would agree with HTH. In addition, if it has a lot of hours on it and you have not frequently greased the gearhead, I would suspect wear in the bevel gears or wear in the splines fittings on either end of the drive shaft.

take the head off and run it that will tell you all you need to know
