Remove old garden trimmer head

Also I am eyeing the Incgo batter garden trimmer, since I do have the battery and charger I got with a drill for Xmas.

That is a mark i made with the vice grip, there was no marks on it

I tried a vice and a 13 ring but the vice kept on slipping on the soft metal

Interesting.Mind had a groove for a screwdriver on the back of the shaft.It was too soft though and basically became too wide. Did you apply the righty loosy though instead of lefty loosy? As the thread is other way around.So turn the nut clockwise.

The new head does not exactly work well either, I have to keep opening it up when I need more line.
I think that it's time for a new trimmer.

I will be binning mine this weekend, It is an Italian electric one that has given me 30 years of trouble-free service until six months ago when the first head hassles started. I had to get a replacement for another one and then do some very fancy machining and customising to get it to work. It is a mission to work on these things.

And yes the threads are LH. The answer about getting to old one off is unfortunately a strip down, a vice and removing the head WITHOUT cutting away the plastic! You lose all the leverage by cutting off the plastic.
The Italians clearly saw the hassles and provided for a locking pin through the body of the unit to lock the shaft without then having to strip it. but then things were made properly 30 - 40 years ago.

The only replacement I will consider would be a Stihl electric

I checked it up and down left to right cant see any way to lock the shaft, nothing i can see without hurting the windings

and the other end of the shaft on the other side of the motor? No slot cut into it? For a large screwdriver?

Thank you Oom @Geoff.D , makes me feel a little more better about throwing out not one, but two of these trimmers, the first a 900W Tantrim (based on my experience with bulletproof Tandem mowers), the other one a Trimtech 900W. Yes, I actually bought two in the vain hope that one could serve as spares :laugh: I reckoned that there is no way in hell that Tandem would make/brand/sell a lemon, and I was completely wrong. Dis kak vannie willle hond.

Which electric Stihl exactly are you looking at? I have a very small fscking tiny place in comparison to the hectares in Wilgers, but I need to make a good decision on a trimmer, was even considering going petrol (despite having solar energy).

I looked a while ago, but put the decision off until I get to my new abode with a much smaller garden. I saw two models, cord and cordless. Think the cordless version has some advantages.
The other pain in the arse with these things (even the Italian one) is the winding of the line to get it right so it does not bind inside and feeds out properly without too much wastage. Them German ones have a much easier way to load line.
 
Used my wifes gas torch from the kitchen. Played the heat on the nut for a bit. Left hand thread so turn nut clockwise to loosen. Vise grips on the shaft. Socket and ratchet to the nut. Nut came away fairly easily.

I actually did not think about heat. Blow torch it is.

Morning thank you, i will try that before i strip the motor
 
I'm in the same boat, our old 650W Trimtech has been in a state of non working for a couple of years. This thread has inspired me to actually take a look at it.

Tested the motor first and that is working. The head was broken off with a piece of blue plastic stuck to the shaft. Not sure if this is supposed to be there or if it was an aftermarket MacGyver fix. I took the motor out of the trimmer body and proceeded to cut away at it until I found a normal M8 nut and was able to get it off as my shaft at the back does have a slot for a screwdriver.

Bought a replacement head but now I am lost as it seems the shaft on the motor does not extend deep enough into the replacement head to actually screw into the embedded nut. Is my trimmer somehow too old to use the standard trimtech/tandem/wolf head? Or does it require a new whatever that blue thing was that was broken off onto the shaft?

I bought the 8mm head but the nut was to big for the 650 so i replaced it with the old nut that i took of, ll fixed and working again
Just check take the string holder of and in the center were the spring goes over is a hexagon plastic, that can be removes with a long nose pliers, just pull it out. the nut is inside there, take the new one out and replace with the old one, replace the hexagon plastic so that the bolt is nice and tight and screw on the head
