Bosch Combitrim 23

I have a 7 year-old Bosch Combitrim 23 (electric) and the head onto which the dual-sided plastic string is fixed now just comes off, because of wear and tear.

I visited a local repairman I've used before and he looked up the serial number for the strimmer and couldn't find any of the relevant parts, so he says they must not make them.

The strimmer is electrically fine and all it needs is a new head (or the old head fixing to the rotating spindle) - is it true that it can't be mended, and if so and I have to buy a new strimmer (small back and front garden so don't need a monster!) what would be a good one to buy where I avoid this parts problem again? I hate throwing away good tools...

Not sure if it's the model you have. If not check with the same company for parts.

Hopefully you have better luck than I have with my Weedeater model 509. I need a new head assembly but ALL parts for this machine are obsolete and unavailable. Darn shame as the motor runs fine.

I suppose you guys have already considered those drive adapters that might allow you to use a universal head ?

Craftsman's Weedeater 509 was actually made by Poulan; are those parts also discontinued and/or obsolete ?

Mine is a genuine Weedeater, not a Craftsman. It may have been made by Poulan as Internet research seems to support that idea. It has a straight 5/8 inch shaft with a standard 5/8 inch thread on the end. None of the "universal" replacement heads I have seen seem to support a straight shaft, all requiring a hexagon shaft AND they all have smaller holes (maybe 3/8 inch) for the threaded part of the shaft.

I have looked at "universal" and specific brand replacement heads in the big box stores and none come close to being applicable. Internet searches all turn up results that state the parts are obsolete or unavailable.

Since your trimmer is electric finding parts is going to be very difficult, maybe you could adapt one like in the video below, if you can only put one string in it. Have a good one. Geo
