Twas the kinda thing I was thinking, along the lines of what Rory has mentioned too.

they do some nice floaty ADT’s.. all depends how long you want to be there for I guess..

The trouble with using any wheeled machine in that environment is two fold. Firstly the mess created will almost certainly need to be corrected..... You'll get away with it on wetland jobs with the magical word "microtopography" however on heathland or similar leaving ruts will be negative.

You can easily sell the tracked dumper to the client with the words LGP and soil compaction..... We don't need to explain how well others have bullshitted there way along with the fantastic use of these buzzwords.

Yes dumpers on flotations exist...... They will tick boxes and we have and do often use hydremas in particular. I'd never price a job like this with short hauls based on there use and nor would I use them unless in the depths of summer. I'd get 360' slew tracked dumpers.... Namely because if your running short hauls the amount of time saved either turning or looping around is significant..... Like significant to the point you don't need more than one dumper.

I have access to tracked dumpers, I am lucky in that respect.... However they are becoming common as muck (same as LR's) because the likes of Lunch, Flannels and that bloke that owned fork rent and has too much money have brought them in an attempt to flood the market..... There getting cheaper by the week.

Regards your digger.... Biggest bulking bucket with a edge welded on... But for the project scope doob is looking at going plus 13t isn't actually going to yield much extra profit..... The place where the money will be made is in the transport, not the dig.

Just my opinions which you are free to slag off.

Got to do a last minute quote for some conservation works. When I say last minute, I mean looked at it yesterday and need to do quote today. After they’ve amended the spec yet again. 🙄

I’d welcome opinions from all you who do proper earthworks (ie, nearly everyone on here but me!) as to how long it would take to scrape and move a hectare of bracken mulch. Scraping down 100mm, lightly, bulky sandy mulchy soil as you can imagine. I’m going to caveat the quote by saying it will be moved a maximum of 200m. I’m obviously hoping I can just get a little dozer in there and push it to the edges to make south facing banks for beetles, reptiles etc. but just in case they want to move it to a dump site I need to allow it. Couldn’t get the ‘committee’ to agree anything on site so if I get this quote you the taxpayer will be paying for a wildly inflated, cover all the options job. It’s always the same with village councils, they can never understand that when spending public money they should specify a job clearly.

What would you use to scrape and move the bracken mulch? I’m thinking use dozer blade to scrape and a clamshell grab to load the dumper would be fastest given the bulky nature and lack of precision required. About 5 hectares I think, will tally it all up today when I get the tenth spec revision. Ffs. Sadly it’s sloping ground and soft sand so I don’t think ol backhoe will be much use. Well, not with me at the helm at least 🤣

Experience welcome

That's a fair size...... I've done a similar size but I did not dig down to clear the mulch I used an Amazone Groundkeeper which cut and collected everything

(https://amazone.co.uk/en-gb/product...-collectors/groundkeeper-mounted-mower-101216) (You can hire the equivalents with a tractor)

The one I used left the equivalent of a manicured lawn.

Do you need to get back to bare earth ? You could then just run a harrow over it.

The idea is to remove as much bracken rhizome as practicable whilst leaving a nutrient-poor and relatively sterile ‘scorched earth’ to allow heather to generate with minimal competition. Mowing won’t give that finish.

ah understood, thanks.... I just read up on this approach for grassland management, looks like herbicide, burning or removal as you are doing, it will end up being about 1000 cubic metres? ... sorry no experience of this
I did some quick maths for a 13 ton digger will be interesting to see how the experts estimate , if you don't mind sharing:
13 ton digger bucket capacity about 0.8 cubic metres
3 cubic metre dumper
10 min round trip time
approx 60 hours , if 6 hour working days around 10 days.....
Apologies in advance for irrelevant answer !

My opinion, and what it’s worth is what you’re paying for it.

If I was tackling this it would be between a dozer, (anywhere from a D3 up to no bigger than a D6N wide track) or my weapon of choice, a 953. One man, just over a week, (assuming sandy soil, bit longer for loam or peat) and it is possible to do it with either without messing up the underlying material, if you have an operator who’s tackled this sort of work before. A small dozer will do it, it just takes longer. No reflection on your abilities but this isn’t the job to be doing with either machine on self drive if you’re new to them.

if you really want To do it yourself, refer to previous replies.
