Interestingly I have recently tried some slabwood processed through Will's branch logger and they are just this size, can be shoveled into the stove.

IIRC it's an indexator GV3, I imagine the seals are available but it would need very clean bench to work on them.

I once had the TP860 on the back of the 1164 you have in order to crane feed it, As you will realise operating that crane at the same time as maintaining 1000rpm at the PTO becomes a bit of a problem. Nor me when properly inserted, I have had them pop out when I have not rotated the collar away from the unlock pin.

These are interesting devices but as they have a high pressure carry over be aware that the flow dumped via them will be dumped from whatever pressure the main service is operating. As pressure times flow is power then power dissipated in the whole flow will be proportional to the power dissipated in the load i.e the heating effect will be the same as if the whole flow was doing work at the same pressure as the load (because the bypass flow is doing no work it will all be expressed as heat)

That sounds like you will be throttling it on the spool, which may cause heating unless it's a closed circuit system. I've previously done away with the quick connectors when they restricted flow too much and caused the oil to heat.

It's not something I have experienced, even with a quick release supply to a FAE mulcher. Does it get hot at all?

It's normal to have a bigger hose to the spool and then smaller outlets from the spool to the services, also a still bigger return hose to tank. This is to reduce internal friction as the flow is constantly running through the valve block but intermittently going to the service ports., Return to tank is larger to prevent pressure build up in valve block. My point about working pressure is because typically a 3/4" 2 wire hose has a working pressure of about 1500psi and agricultural kit tends to have relief valves set at about 2000psi.

Has the axle a square tube with lever arms on rubber suspension? If so there may be a manufacturer’s plate on the square tube, anyway it won't be hard to spec a replacement from Knott-Avonride Limited: Axles & Suspension Units I bought a replacement 1300kg axle with hubs for £360 inc VAT and delivery in March.

You are right but at the limit bigger bore pipes withstand less pressure than smaller, so check the working pressure of the pipe.

I'm sure he's only using it to assist in composting the stump. If I were doing it I'd have to get PA1 and resurrect my drench gun, a shot of glyphosate followed by a plug of clay should be effective.

I'm keeping an eye on this, never having done it prior to grinding. What experience have people with using herbicide prior to felling to reduce suckering? Trees I'd treat would be tree of heaven Ailanthus Altissima, staghorn sumac Rhus Typhnia, poplars and robinia, what others? Cheaper to use 50% glyphosate in same hole

I'm with Rover on this one, a person who puts a product on the market is required to prepare a technical file showing how the machine conforms with all of the legal requirements to achieve CE marking. He then issues a certificate of conformity, as far as I can see no other bodies need to be involved.

Laying it or if the adjacent species will layer peg them into the gap, you can cut back the sycamore to prevent it shading new growth. As has been said it's plain to see that it has been the flailing that has caused the gappiness and laying is the remedy.

So someone has been burning wet wood or the device hasn't got up to temperature.

Pay heed to Woodworks

If the bearings surfaces are up to the load and mean piston speed low, so wear isn't an issue (and I've had a cooked transit tdci apart at 100k miles with no discernible bore wear) then the lower internal surface area will reduce heat loss for a given power. Small swept volume in a substantial block should be better than large swept volume and proportionally lower power.

Certainly is too close. Get the serial numbers onto arbsafe, it needs a big corpus to be effective. People buying used saws should check serial numbers against the arbsafe database as a matter of course. I've still a few tools if you need a borrow Richard

Sorry cannot help with the plough but unless money is no object I wouldn't plough, but has a residual herbicide been used? The ground is weed free from the growing of the maize, so the only reason for ploughing is to bury the stubble, I think I'd just disc it, broadcast a paddock mixture and roll. Flailing in the spring to tiller the grass once it's firmly rooted will deal with the stubble that’s still sticking up.

See further up the thread, I thought it illegal also but cannot find the legislation, the only thing I did see is that a secondary coupling needs to be short enough to prevent the tow hitch hitting the ground..So a security chain long enough not to interfere with the breakaway cable may be acceptable if my memory has deceived me again. I'd stick with making sure the brakes work well and the breakaway cable because having a trailer attached to a long chain with the brakes slammed on may cause more damage to the tow vehicle.

Pretty but that flame not holding means there's CO being wasted and vented till the next one ignites

My old boss just called round to chip some shrubs for me, he used a promark with a Wisconsin engine in the past and said the petrol cost was crippling. Even the 27hp Kohler in the dosko stump grinder can use 40 litres of petrol in a hard day.

I've had a brief look and haven't found anything that says you cannot have a secondary coupling and a breakaway coupling but as you say the secondary coupling would have to be long enough not to interfere with the breakaway coupling. Someone else may know better

Diesel chainsaw? They do take longer to warm up on a cold day, mine is still zero road tax from when diesel was going to save the planet. It'll be a bit damp from that coat rack today

That makes sense but I thought the legal requirement was no chain with overrun brakes, just the break away cable. A chain must be used with unbraked trailer under 750kg and must be short enough to prevent the drawbar hitting the ground if the trailer detaches.

Yes basically. I know little about denatured ethyl alcohol but back in the day methanol fueled grasstrack bikes ran much higher compression ratios with 500cc JAP engines, probably over 12:1 and the carbs were able to accept bigger jets, also I think the jets were not brass as the fuel attacked brass. Unleaded can probably only stand about 10:1 cr ( but maybe higher with a knock sensor which could retard the ignition, even so this would derate it) and power is in direct proportion to compression, all other things being equal. So to get the best out of E85 the engine needs to be higher compression and free of brass and some other metal bits in the fuel system plus no rubber or organic hoses or gaskets. Plus 30% bigger jets or preferably injectors. Then the higher compression should go a small way toward addressing the 25% higher fuel consumption. Much the same is true of LPG (propane) to get the best out of it needs a higher compression ratio to take the advantage of its higher octane rating (which means it resists detonation to higher pressures). I've never seen E85 for sale in UK is it much cheaper in France?
