Interestingly that correctly shows the TU16, which I have and earlier said T15, but the TU32 pdf is actually the T35, which I have, and does show the speed change. I somehow doubt the TU32 is a two speed.

I am not sure of the differences between TU and T  but the gearing is by changing the distance from the pivot point, the pin on which the power lever pivots is an eccentric which is fixed by the little knob in the top of the power lever, pull this out and rotate the shaft until the knob can drop back in.

 

I only have a vague memory as I always left it in low and took the T15 if I wanted faster.

Yes, I figured out that was likely how it worked but I think the pin on mine may be slightly bent ... I didn't want to force it not being 100% sure of it's operation.

 

I'll have another go tomorrow, I've been looking for a longer rope for quite a while and I see from the pdf the standard length was 20m.

 

Tractel seem to do 10, 20 and 30m lengths with the later being over £300 which I couldn't really justify although it would save a lot of repetitive taking up slack, cheers.

The T35 and several others of its era don't have shear pins. You'll see in the manual that the handle is called a safety device, that's because it has a weak ring milled around it, so the handle bends over if you go at things like a gorilla.

With a shear pin machine you can go wild with long scaffold poles if you fancy, but on the T35 it's not a terribly bright idea if you're keen to dreadfully punish some poor innocent roots

I''ve at TU35, it's a beast when needed... but adding extra leverage enables you to push any mechanism beyond it's design limits👍
