I learned Gold under Gorse Bronze under Bracken and Copper under heather It would be interesting to know if bracken bearing land is inherently more fertile than gorse. Adding FYM to the cleared "furzefield" should show returns. They are all observations from farmers about the underlying fertility of the particular soils. In high P&K status soils gorse can compete because it is a legume and symbiotic microbes fix atmospheric nitrogen for it. Heather can exist on low nutrient sites because it has the ability to scavenge and lock up the availbale nitrogen to prevent competition from grasses. Narthecium ossifragum the bog asphodel gets its latin name from the fact that animals grazed on the acid pastures where it grew had weak bones. Think os for the french for bone and fragile and you may see a connection with the latin.

Gorse indicates good phosphate and posasium availability and low nitrogen, that is why it fixes its own.

The early Asplundh looked similar to the Gibbs Woodchuck, this was an american import and the first chipper I used in 1976, Gibbs took the large petrol engine out and fitted a diesel. This was always an arb disposal machine. During this period the FC were investigating wood chip firing from lop and top, in East Anglia there were some self propelled drum machines and also some large angled disc chippers. In Surrey/Hampshire we were smaller scale so the FC arranged a demo of a small tractor mounted Jensen, It was less than 6" and the demonstrator had lost an arm in a sawmill accident, what fascinated me was the feed was no longer inclined to the disc and it still chipped and loaded whereas I knew the angled feed gave big problems as the blades blunted. Most chippers were horribly expensive and just as Amstrad introduced an affordable soho computer Jim Wilkie at Exenco introduced his chuck and duck, just like the computer analogy whilst cheap it was a fork that died out in favour of towed disc chippers. Michael had them manufactured near Dorking before he sourced them abroad, I remember watching Derek turning the flywheels on his lathe in an old cowshed.

Difficult for petrol and the upfront cost is a killer buying 1000ltrs plus I only managed to save 6p/litre

Rather than a metal plate get a sheet oo old conveyor and fix that at the tail gate end, lay it flat on the floor and up the rear bulkhead. then with a rope over the top you can roll the load out. Still probably not worthwhile compared with the ease of a tipper.

That's pilot operated valves I think I've never got very fluent with common knowledge controls but this firm Hydraulic Valve Control Cables Hindle Controls did produce a cable kit to give a joystick action for the 4 slices of slew, lift,jib and rotate and I think a twist action was available at the top for grab and extend.

Sorry Eddy I didn't mean to cast aspersions about those arborists who care as opposed to the loppers I deal with. I was going to post a picture from a tree report I did after a subcontract gang had raced through a car park but then realised the line manager had deleted the jpegs. In fact the damage is more aesthetically annoying than damaging as it takes place in live wood which can heal. Still poor practice because of the disfiguring.

Meetens 01772 691604 were always good for me but I haven't used them since they relocated from Surrey to Preston.

Wind it up and then push a loop through the D ring, invert this loop over the coil of tape. NB this shortens the life of the tape as it flexes the bit attached to the ring.

Thanks spud, diaphragm looked good, filter from pump section to metering valve clear, I bought this from new 2 years ago and whilst I hadn't seen it for two years I am certain it has not been opened up, our guys just return faulty gear to base. The welch plugs looked good and seemed to a have a fillet of red sealant around them. Choke is external on these and was off. having convinced myself it was an over fuelling issue I'm now not sure that the 4 stroking was over fuelling, it ticks over fine but doesn't make the transition to HI idle. It will not rev high enough to engage the clutch. I'm going to change the plug and see if I can drip a little fuel in at full throttle to see if it will pick upon Tuesday.

As I have observed here before UA types are born with the congenital deformity of a spike growing out of their ankles.

Electricity act 1989 shedule 4 9 (2)The licence holder may give notice to the occupier of the land requiring him to fell or lop the tree or cut back its roots so as to prevent it from having the effect mentioned in sub-paragraph (1)(a) or (b) above, subject to the payment to him by the licence holder of the expenses reasonably incurred by him in complying with the notice.

Coppard Hire do an RC 100 with a seppi or foresatl flail but it costs over £500/day. Practicality Brown had a similar one 6 years ago.

I have had one of these drills returned as it was rough running. Had a quick peek in the exhaust and bore and rings OK but it is running very rich even with filter off and HI and LO screws on minimum. I have had something similar before on a Husky when a welch plug leaked but before I take the carb apart any suggestions?

Yes I was getting my terminology wrong, rail=line blockage ua=shutdown, I do both occasionally but never get involved with the safe system of work. In fact when I was in the situation of letting these other ua contractors across my worksite it wasn't that they objected to my doing the work but more that their payment system would not allow me payment and I could see I would have to take them to court to get the money.

It can be worse than a straight line correlation as the higher the moisture content the more primary air you need and this adds massflow which means the fire may never reach a good working temperature. Also the dew point of the flue gases is lower so condensation occurs at a higher temperature which is why it is necessary for the flue gas to be at above 100C as it leaves the stack, given that a condensing gas boiler will vent its flue at 50C with the water as visible droplets and you can see a woodfire will always be wasting more flue heat than a condensing boiler. Having said that a general ruel I use is to take the oven dry weight of logs I have and multiply by 18.6MJ per kg od (for hardwood) then subtract 2.7MJ for every kg of water (neglecting water formed in combustion). So a 2kg log at 15% mc wwb will have 1.7 kg od and .3kg moisture and burned cleanly the most heat you will get out will be 1.7*18.6-.3*2.7=30.81MJ in practice you cannot get this heat into the room because you have to raise the temperature of the combustion air to the flue temperature and dump it up the stack, whilst a gas fire may only need 10% more air than the stoichiometric amount (this is the amount of air needed for there to be the exact amount of oxygen to combine with the fuel) the woodfire will typically need 100% more air and this excess air gets a free ride from the room and up the chimney carrying heat with it.

They tend to be inter related, moisture needs a lot of heat to turn it to steam, 1 litre of water needs 4.186 kJoule for each degree you heat it up so you need 4.186*90=94.186kJ to get it from 10C to boiling but then have to add 2.300kJ to turn it to steam. It's robbing this heat from the fire that quenches the flames and prevents combustion from completing and it's the products of incomplete combustion that then condense out with the steam to foul the chimney.

Easy enough with mapmaker but you'll need the pro version. I'm not very good with databases but have tried to adapt ones (for team skills)and think it best to start from scratch. You need to consider the basic architecture of what you want out of the database. It's easy enough to create a flat table with a record consisting of a unique index co-ordinates, tag ( but who needs a tag if the co-ordinates are accurate and replicable), heigh, girth, crown spread, condition and date. What else are you wanting?

The black cab ones will be 15 years old won't they? How would their productivity compare with the Logset Titan I was watching on Sunday? I've been looking at two 840s, cheap enough at £5k but what expensive repairs might they be hiding, not to mention cost of tyres.

The legislation allows a landowner to do the work and reclaim reasonable costs. Getting the agreements in place for a line blockage would be a problem though.

When we handballed pulpwood onto trailers we reckoned 1 tonne per man per 20 minutes was good going

I've just paid 65.75p for gasoil with similar cv I think that is a bit low, hardwood oven dry is about 18.6MJ/kg and the additional losses from dumping the extra 15% moisture as vapour up the flue is only about 0.5MJ, bigger losses are likely from excess air. Whatever your customers will stand, it is a luxury good and not a fuel

My colleague Danny made a plate with 6mm holes which he had a shallow countersink so the edges were sharp, we prepared 1" disks of dry pine between the whorls and forced them through to make some pellets. It worked in a fashion because the wood could compress but wet wood jammed it completely.

Caveat Emptor

I always thought the Highland bear was an 1164 with cranab 4510 on the roof and either 4,5 or 8 tonne double drum winches and a log rolling blade.
