  1. Yes and similar can be said for burning, it causes more damage than it's worth.
  2. I'm thinking of getting a capstan winch for a job where access for a machine is difficult. I'm wondering what rope, with a working pull of a 10kN, about a tonne force, might be best? And if LOLER failed climbing and rigging ropes might be available as there will be no suspended loads?
  3. Good at least we have some common ground
  4. Exactly. I have been a fan of renewable energy since the 70s, it hasn't stopped me driving cars or tractors but I do aim to conserve fuel. In the meanwhile because of fears of damage we are doing by releasing so much CO2 renewable energy has really taken off. Even the Saudis know they have to spread the risk of oil dependence, hence their announcement to float their oil company.
  5. Amusing fake factoid but not the reason for having pollution controls on diesel engines. I doubt the particulate problem is significant outside of urban areas but that's where most arb work occurs
  6. I think most votes go for this type of containment, I've no experience of it but see plenty of hardstands under trees locally so I think it would work. I like the idea of pea shingle rather than limestone scalpings as this will be an acid soil and pea shingle will not leach calcium ions into the soil and alter the environment for the tree roots. I would talk with the highways people to try and prevent further erosion from vehicles mounting the kerb.
  7. I take it the main flow controls the slew, boom, dipper, extension and crowd and the auxiliary is just for implements? What are normal main flow pressures and how much less is the auxiliary?
  8. Some breeds are naturally polled (hornless) but there is a genetic link between some desirable trait and horns IIRC, so while our hereford cross animals were hornless the pure friesans kept as herd replacements were not, so were disbudded. In the days of milking in stalls horns were not a problem but once they were in a proper milking shed the horns and aggression in the confined space was a problem. Also memory from 45 years back when I last milked a cow.
  9. I may well change my mind about not replacing my petroil powered hedge cutter after my day today. The local Ramblers group volunteered to clear a 800metre path that had become overgrown such that it was impassible. As the highway authority have abdicated their responsibility to keep it managed there was no other option. The HA supervisor accompanied us and provided two KMA 130 R power heads with triblade cutter heads, the gear heads did look a bit anorexic but didn't break. The back pack batteries were the AR 3000. I was well impressed as the cutters were light enough to use at any angle and would cut woody side growth of 10mm as well as mow grass and bramble. The HA would only allow an operator 1 hour trigger time so each only ran for 2 hours ( there was noticeable vibration as one was holding the trigger and front handle mounted on the pole, with a normal brushcutter this is better isolated by the handles and grips). Conversely this holding arrangement gives far better articulation of the cutting head. We had the luxury of a couple of volunteers acting as banksmen and raking up arisings 5 m to the rear. Normally I would use a mulching cutter on the FS 360 to avoid the need for clearing up. So I would be happy to use this in place of my long reach hedge cutter and as a short polesaw, I don't think it would replace the power of the mulching head on the 360. I think someone said the attachments for my defunct ryobi lend out saw can be made to fit so I am considering having a punt at the KMA 130 R power head at 250 quid plus VAT but I wouldn't lash out on the big battery as I'd only need 1-2 hours trigger time. Not sure what battery and charger combination to choose though.
  10. It's not something I have come across but you have to consider who you are contracting with, if it's the owner you accept instruction from them and they pay you, they then reclaim from the insurer.
  11. I didn't read it as that; there is a vast range of skills and intelligence and everyone settles into the niche that fits them. The most intelligent are not necessarily the most astute or cunning so no reason they should become richest. Everybody has to live no matter their skill levels.
  12. I should do my late sister lived 3 houses up and @Deafhead and I quoted for my first elm felling job on the field at the back , but didn't get it. Yes, my daughter's but he's a mongrel.
  13. I think he will need to scrape off the mud and get a reasonably level area and lift the paved path to the front door before deploying the teram and cellweb. At least drainage is not an issue being on a hillside. The soil is sandy and has good bearing capacity, many older houses only have 60cms footings here. The thing I notice is that the front of the bank has been eroded already by lorries mounting the kerb to pass cars on this narrow rat run. At least the oaks are to the north of the property so shading is less of an issue but they will have grown quite a bit in the last 60 years. I wonder if @Deafhead is reading this as he an his father may well have built the original house prior to the extensions.
  14. I've mentioned this several times before; as you say the oil is foaming because air is being sucked in. With cold oil this can be from a seal failure somewhere but also that the oil in the tank is being sucked into a vortex because it is viscous, just like the vortex when the bath water goes down the drain, the air then get sucked down the middle. So the oil should be circulated at low rpm for a while to get warm and less viscous. The other thing is that the oil may be being returned above the level in the tank and entraining air as it splashes around.
  15. Yes, capitalism has been the first system that mimics human evolution, it builds on previously created exploitation of all resources and leads to economic growth. This is how people can gain vast wealth without resorting to warfare. Unchecked it means the devil takes the hindmost, it also means the also rans are simply exploited and then discarded when they no longer contribute. My question is where are we going that we benefit from unlimited growth, it's plainly not possible to last indefinitely, at some stage we have to sit back and consider how we sustain the planet, population and economy. Given that pure capitalism is not acceptable to any but the most successful we have created laws to regulate it to enable the bulk of UK dwellers a decent quality of life but it's a complicated system to police. In the meanwhile the people at the top of the pyramid have a propensity to consume resources and pollute to much higher degrees than is good for our environment.
  16. @Justme will know chapter and verse but there were changes for people passing their test after 2013 but they still allow the towing of a trailer up to 750kg, the total MAM of 3500kg applies if the trailer is greater than 750kg MAM in which case the MAM of the vehicle plus the MAM of the trailer must be less than 3500kg.
  17. They cannot fix it any more than they can fix the current problem simply because it is the result of a poor government policy decision over 30 years ago.
  18. Yes our steel tipper bodied LDV with the Duratec engine weighed 2100 empty but with half a tank of fuel. None of our mk 6 or 7 transit tippers were that light and the two arb bodied ones where 2700 unladen.
  19. Doh you can tell I've been retired 3 years. I was used to seeing SSoW, safe system of work
  20. I cannot help but do you mean a Ramsar wetland?
  21. As @Dan Maynard pointed out I had done a rapid calculation on the gross torque figure given by the OP and that torque has to rotate the whole weight of the main boom, dipper, rotator and grapple and lift the load at the distance from the hinge pin, resulting in a much reduced weight of log. As I said my cranab 4510 (45 years old now) will lift 2 tonnes close in if the tractor doesn't fall over.
  22. I was thinking strimmer damage had let something nasty in, then wondered if a herbicide had also been used to screef those bare patches around the bases.
  23. Before the days of synthetic oils I changed from the blue Husqvarna oil to the red Stihl oil just because I could see the pink mix more easily. Now I have trouble seeing the Stihl ultra green and would move to a red synthetic too.
  24. Twenty years ago I was developing clean charcoal making, mainly to reduce the pollution and low thermal efficiency of making charcoal for cooking. At the same time scientists researching soils were talking about some fertile areas in the am'azon which appeared to have been be modified by humans, "terra preta des indios". These soils had a large char component and were produced centuries ago. So people looked at reproducing this terra preta to increase fertility and restore damaged soils in the tropics. An ex pat, the late Peter Reed, coined the term biochar to differentiate char used as soil amelioration from that used for cooking. As we were made more aware of the significance of increased CO2 emissions the second benefit of sequestering carbon by breaking into the photosynthesis to decay cycle and making a portion of the biomass recalcitrant became appealing.
  25. Yes, because they imbibe less air fuel mix so that the first slug out of the transfer port is just air, and hence less fuel:air mix exits the exhaust unburned it follows that less lube passes through the system for a given duty cycle, so I too thought this was the reason for needing a higher quality oil.
