    As Spud says you must avoid glazing the bore. Easy to be over cautious with a new engine. Common thinking is to treat any new engine as normal but probably best to let it rest (work easy) between hard use and don't over rev it.

    First thing you need to establish is power to the charger. They normally have a mains and output fuse. Check them. Have you a multimeter, if so try and trace the circuit through the charger. They are more complicated than you would think though. Probably have a monitor circuit which triggers a relay. Check the transformer output and input coils. Any printed circuit boards in there, have a look at for blackened components. If electrics are not your strong point then you might need outside help. Just a few ideas for you to start on.

    If you could find a RHI compliant wood chip boiler installation that was on idle or off in the summer you might be able to do a deal with them. We are currently investigating a drier to run through the summer. Any one near you? Nursery would be a good bet.

    Sorry Spaceman memory must be going. Had a look today and the wood we were chipping had a lot of small in it so I would say an average of 300mm dia. Chipper crane just picks up several instead. Some other batches would average 400 but not the one we were chipping. The guy who operates the chipper and crane is very good and with 780hp it doesn't slow down for much.

    Lots of things they did wrong as well as that IMO.

    I think I should have sold my shares 2 years ago.

    We dry 3000 tonnes a year on a windy site and after 2 years the top of the stack is close to 25%MC. Bottom metre or so can be 40% as the wind does not get through. Stacks are up to 5 metres high and uncovered. Variety of species but a lot of larch. Average diameter around 400mm. Some up to 1metre dia which are obviously much wetter. Prevailing wind hits at 45 deg so blows up between the stacks and through them. All measurements taken in dry weather. Regards

    Careful if you go down past Hayle. Pasty meat down there has a touristy flavour

    Lucky escape, when I was self employed I got caught a couple of times. Not good especially if you have supplied a ruck of parts. Higher cutter prices might have been, just a couple thinking to make a bit over the top from a "green" buyer. Problem was it helped drive us to use Euro forest almost exclusively. As you say they might only make a pound or two on the cutter and haulage prices but it does mount up. I suppose our security of supply and price equates to your security of payment so we both benefit to a degree.

    I sympathise with the cutters but from an end users point Euroforest are good to deal with and I can see their role in the supply chain. 7 years ago when we started using biomass for heating I set out to buy direct from several sources. However this had many problems. Slab wood was full of sawdust and rubbish including a scaffold tube. When a power station offered a higher price, agreed deals went out the window and we were left short of wood. Prices direct from cutters were higher than Euro forest. Every supplier wanted a different price so that was a recipe for bad feeling as there are no secrets in the wood world. Buying about 3k. Tonnes per annum from Euroforest we have security of supply and price. Negation of price is simple and painless ( for us anyway) I am not sure what the answer is but when you have one large company in the supply chain it will have a lot of say in prices and work allocation.

    Windy site will do it. Depends on the species and size of course. Covering 6000 tonnes of round wood does not appeal to me and I am sure Dan feels the same. Wonder what the HSE would think about someone climbing around wood piles.
  12. cornish wood burner
    That's another way but not for us at the moment. Space, energy and capital outlay would be a significant amount. We have started looking into burning our plant/peat waste and might dry some of that at some point. Looking at a shredder for that on Wednesday.
  13. cornish wood burner
    Up to 2 years if we can. MC is around 25% to 30% for round. Slabwood I have seen sub 20%
  14. cornish wood burner
    That's the one. Variety of reasons why we don't chip directly into the store but it works for us.
  15. cornish wood burner
    We have had bigger but the one we use now is in the region of £250/hour Tonnage depends on how its fed and whether it needs to move, MC of the wood, blown or conveyed from the machine, screen size, size of wood, type of wood and ease of handling it. For us we get about 50 tonnes per hour of 25% MC G50 loading trailers.

    This may be stating the obvious but a LSD will only help if you have unequal weight or traction on the drive wheels. So across a slope, tight uphill corners or one wheel on mud would make it usefull. Weight and tyres make the biggest difference. You need to access where you go and consider if it will make a difference to you.

    With a properly designed system ie walking floor and fairly level or level augers then a percentage of fines should present no problem. IMO sweep arms and steep augers have no place in commercial systems, far too fussy and unreliable. In view of the stone and dirt problem, the questionable economics and the loss of nutrients it looks bleak for these brash balers on harvesting sites. Regarding brash chipping I was thinking more of small scale one time only site clearance and trimming operations.
  19. cornish wood burner
    Sounds a good MC presumably kiln dried. I normally aim for 20 to 35% air dried but can burn up to 50% at a push. Not really worth much to us at that % though. When we hire a chipper to chip for us we normally aim for G50 or G100 mainly round but sometimes some slab. Problem comes when we get offered chip from outside. Varies from average to rubbish normally. We have used a heizohack in our earlier days and found it to be very good. It makes sense that a small screen when chipping brash is the way to go. Perhaps those chipping brash and supplying biomass or just dumping in biomass stores might like to follow your example.
  20. cornish wood burner
    Fines are not our and I suspect most other medium sized biomass users problem. The main problem is long twigs that block the sensor sight from sender to reciever and give a false "the auger is full signal" If this can be overcome we would be happy to take a large quantity of brash chip. We use around 3000 tons per year so a reasonable percentage of that could be accepted. The drier the better obviously which would be reflected in the price.
  21. cornish wood burner
    Its all relative. Big cost big hourly rate. Cannot comment on harvesters just chippers but I expect the same applies. A large chipper is the cheapest way to chip if you price it per ton. We have a "mega chipper" chip for us for our biomass boilers and we have never had it beaten for price. We therefore do not mind paying big hourly rates.

    Thanks aiden Good luck with the business Ian

    Certainly early K series ( petrol ) had a head gasket weakness. There was a modifoed head gasket fitted later and presumably that applies to the freelander. Not sure of the exact date but circa 03 I guess. Alternator bearings were very weak again certainly on the early ones.

    My 8 ton electric has never failed to split anything I can lift onto it. Up to 700mm has been no problem. Oak, birch even with knots all goes. In fact it has a dual speed and most smaller rounds or pieces I can split at the faster 4 ton. It has wedges from both ends so saves choosing the weakest end which is probably an advantage but it shows what even low tonnage can do. I would say the lighter 7 ton if you are going to move it
  25. cornish wood burner
    Quality any good for biomass? I know its a good chipper on normal sized wood but the reason I ask we have received a lot of rubbish chip from brash so wondered what the heizo was like chipping it.
