Husqvarna 550xp Manual gives saw chain speed at maximum engine power as 19.6m/s, s, so Class 1 PPE would be totally adequate. Other factors in a Risk Assessment might include the likelihood of increased fatigue or overheating from higher class, heavier PPE, justifying a lower class.

Do the folk who don't use helmet chinstraps also not use seatbelts?

Ash tree crown reduction excessive
krummholz replied to ashtreeguy's question in Homeowners Tree Advice Forum
It may be that they're establishing a Pollard structure given that the trees are so young. Were the previous works a reduction or a crown raise? Your last image (the "before" pic) has a few pruning cuts on the ash lower down. -
Is EN certification and a CE mark on the cards?

Would you say this tree is too dangerous to climb and dismantle
krummholz replied to TreecisionJp's topic in Climbers talk
@TreecisionJp Remember to check for bats too, that crack is a potential roost feature. Can you leave a spar standing with the crack in it? Looks like it could be far away enough from the road. -

As others have pointed out, you'd be hard pushed to justify why you skipped past using a MEWP on your Hierarchy of Controls if there's good access for using one on a clearly structurally compromised tree. -
Nothing wrong with using an old climbing rope for rigging as long as it's given an appropriate SWL. I'm guessing that wasn't the case here though.

So what's your advice in this instance?

Anyone using a separate harken Winch like what Drew Bristow does in Fiji? Seems like a lightweight, versatile set up that's cheaper than a GRCS or smart winch if you've already got a decent lowering bollard. Looks like he has the 500 - the WLL of 5kN doesn't sound like a lot though...

Certainly looks like it could be dessicated Trametes spp. fruiting bodies but, as you say, the image quality is pretty poor.

Advice on trees that have been aggressively pollarded
krummholz replied to Hobbittree's topic in Trees and the Law
No not at all - was just curious and went down a bit of a rabbit hole. -
Advice on trees that have been aggressively pollarded
krummholz replied to Hobbittree's topic in Trees and the Law
Just to further assure you that everything was kosher - all the lime trees pollarded have Tree Preservation Orders on them, and all works to them have to have prior approval and consent from the Local Planning Authority. You can find the application and consent documents for the most recent works online on the Stroud Planning Portal. -
I'd also suggest to the client (if the surveyor hasn't already) that the bracing be inspected on an appropriate cycle and make them aware of the lifespan of the product - I think Cobra is 10 years?
