Negative. Most people would just use a MS200 if they couldn't get hold of an MS200T. And even with the rear handle people would stihl use it one handed - definatley more dangerous than one-handing a top handled saw. Whose thinking of phasing them out anyway? I thought the industry had dealt with that issue a few years back?

Using Climbing Gear From The States In The Uk
scotspine1 replied to Leyburn Lad's topic in Climbers talk
That may be true, I dont know enough about R&D in arboriculture to comment, but when it comes to rigging practices/equipment America led the way. The US arb industry were also the first to build and produce bucket trucks/aerial platforms specifically for urban treework decades ago. From what I've seen we still dont have one single dedicated tree MEWP in Europe. -
Using Climbing Gear From The States In The Uk
scotspine1 replied to Leyburn Lad's topic in Climbers talk
Thats true, people all over the world have been caring for/managing trees for hundreds of years, but 'arboriculture' as we practice it today owes a great deal to the US. Americans in general appreciate trees far more than British people do. You only have to visit the US to realise this. Their long legacy of urban tree management is a sign of the high status in which trees are held in America. Trees are not held in such high esteem in the UK. If it weren't for US model of arboriculture we would still be climbing 60 ft ladders to lop off branches with rusty bowsaws. -
So would yew be after 500 years! Someone started a fire in the main crotch about 20 years ago, the fire damage eventually caused one of the main stems to fail a few weeks ago. With the props to support it, it will be able to regenerate lower down and live for another 500 years....hopefully. Here's its good side...

Some more pics form the job.

After propping that Yew I realise that an engineer with some basic knowledge of tree biology would know how to prop a tree better than any arborist. The reason is that they spend their time building things whereas we spend most of our time knocking things down.

Propped the Ancient Yew this week.
-
Anyone used one of these for treework? Are they any good? Its a 3.5 tonner, would you need to get a tacho fitted if your filling up with chips and towing a chipper daily?

Found this while looking for prop ideas - telescopic fruit tree prop. http://www.propacrop.com/ Too small for big trees, the U shaped limb support seems like a good idea though.
-
I agree, just dont want to rule out a non digging method. Found this pic of the of an ancient Scottish Oak propped with natural wood, looks very good for the setting. The Yew I'm working on is part of an ornamental garden so I dont think the natural wood would be necessary?
-
Tony, I thought about fabric straps, not sure how to attach them to the stems though. How would you mulch around that tree? Steve/Roller, the scaffold pole painted green with foam support would work. The wet concrete excavation might damage the roots, no? as would digging holes for concrete slabs.... Maybe need to think of a way with minimal ground disturbance? Ed, will have a think about that drilling option. Pecon, I agree, Yew is one of those trees I try to save wherever possible. Would be disappointing to loose this one as it sits in the front gardens of this listed building.

Pecon, The original idea was to cable using Cobra, but I decided that the angle was wrong for cabling, poor angles wouldn't allow for any increase in structural stability/strength. There has been end weight taken off the stems already, long term to the plan is to encourage the juvenile growth around the main trunk to slowly replace these large stems. But for the moment, the large stems are needed for feeding. Ed, are you saying to drill holes to hold the yoke/support in place? That might work, they dont have to be too big.

I have decided to put props on this Yew to stop stem failure. It needs 3 props. I was thinking of using some kind of treated wood like telegraph poles/straining posts but smaller diameter. Going to sit the poles on concrete slabs embedded under the grass so they won't be visible on the lawn. Anyone done any propping or got any ideas about what wood to use for the props? How do you make sure the props stay attached to the stems during high winds?
