strimmers - dual or single ?

omplain that their bump-feed strimmers are not auto-feeding ! I also suspec t that the problems with the line disappearing back into the spool are when you do not bump-feed often enough.

Bump feed is OK. The reason the cord disappears inside is that when you hit something too th ick, the cord winds round it and yanks the spool tight instead of cutting. The cords weld together and the end breaks off. Usually inside the layers, so making it hard to find the end.

When this happens, time to fit the brushwood cutting head. Doesn't cut as close though.

The electric motor has a flatter torque characteristic, so when you hit a wodge of grass both types will slow down but the electric one slows down less because it still produces much the same torque as it slows down. At least that's the way it feels to me.

Sounds underpowered... My Stihl petrol (nowhere near top-of-range) doesn't really slow down much at all, no matter what you throw at it - even with the death star in thick stuff.

Now don't be silly, something must slow it down - solid rock etc.?

I find that the stuff which slows mowers, strimmers etc. down most is really thick green grass, even our big Kubota struggles on that sometimes. The strimmer (whether petrol or electric) does too, it's much harder work than nettles or other weeds.
