MATTMOSS

This sounds interesting, I would be keen to read such a paper. I have an assignment to do which involves trying to develop a new (different to what is already available) method of tree risk assessment. I'm currently avoiding it, mainly as I have lots of other things to be getting on with but also because I find it difficult to see beyond QTRA of which I am most familiar.

We have had 6 x ms261 rebuilt with new crank shafts as warranty repairs, free of charge. Hate the things

Hi spud, if your modified saws are anything to go by id love to see your knapsack sprayer. I bet it sprays a twenty foot span and can pass fifteen litres in under ten seconds

Definitely small bits at a time mate. Being inexperienced you will be yet to realise the forces involved when removing large limbs. My advice would be to get an anchor point as high as you can to give most movement not onto the limb and take you time practicing various cuts and letting the wood free fall to the ground without risk of damaging anything, including yourself. Take your time. Make sure there is another climber there just in case. I would not recommend you try and cut a three foot diameter limb off in one. Good luck

What is it that you are actually struggling with? A photo says a thousand words:001_smile: Just to beat anyone else to saying it- this crappy chinese stuff is not worth trying to fix, but you already know that don't you

In my opinion this is just the type of scaremongering that causes the knee jerk reactions from the risk adverse. Has this girl been killed from neglected tree management responsibility or was it just one of those things? Should we cut all the trees down just in case?

Jon, I am not trying to say these trees do not warrant removal, how could I make that judgement from looking at a couple of pictures. Just because I appreciate trees I wouldn't for one minute want to jeopardise anyone's safety, especially any kiddies. All I am trying to say is that when trees of this size, age and stature are being removed- make sure it is the right decision. Trees can co exist with fungal decay for many years and can continue to provide numberous benefits with regular monitoring- this can be perfectly reasonable. My own perception of tree risk has dramatically changed over recent years as I have pursued further education in arboriculture. No tree can be classed as a safe tree however, the risks from trees is extremely low and with reasonable management even lower. If Mr Burch and his client have assessed these trees and concluded that the risks they pose significantly outweighs their benefits and felling them is the most reasonable option, then that is fine by me. I Hope the replacements reach the same maturity. Just provoking thought, not argument. No dramas guys.

you can't blame the lad for trying to display his new found knowledge however, let him know that he has still got a lot to learn and you are the boss. Sounds like you have the job sorted, get the work done Asap and keep your client happy. Give the lad a playful beating for a couple of hours and ask him what his thoughts are on pruning during the summer months to allow the tree to respond to the damage imediatley as opposed to waiting until the onset of growth.

Suppose so, shame.

It's not uncommon for trees of that age to have fungal bracket or two, it's about what extent they are compromised, I can't make it out from the pictures.

Do they need to come out?

Looks well. Could just do with some mulch to finish it nicely!

I just knew it would be the fuel pipe Glad you got it sorted:thumbup1:

I would change the fuel pipe to count that out All together

Do you know that cultivars are under their own code?

Have you got a copy of the Hilliers manual?

Seems like a logical answer.

I am not aware of any other guidance.

I know the standard mentions something about measuring dbh away from an unusually large swelling but I don't think you can reduce the rap because you think it's too much. Your answer lies in bs5873 in any event.

Just out of interest what did you go with alternatively ?

Yes I knew they wouldn't be cheap. Good luck with the job.

About £70 each I guess for that size?

Barchams are the best and also the most expensive.

I'd agree with your thoughts.

You haven't been over tightening them have you Jonny? Not being sarky just asking, I've seen blades crack most from being over tightened or not cleaning the flywheel properly when installing. Never seen them round blades crack tho
