I think this is the best possible result, because you are not going to break anything because of too much torque. Wonderful news!!!
We have seen that woodgas makes more power than chargas before. Chuckw told us chargas is maybe 4 MJ/m3, wood gas is maybe 6 MJ/m3, definitely not worth compressing.
If you could get to 20 MJ/m3 like retort made ‘town gas’ it might be worth it for stationary systems, but probably not for vehicles.
(Natural gas is 36 MJ/m3 for reference.)
Does anyone know the energy density of water gas?

Its important to note that charcoal gas is usualy ment just as the product of air and charcoal reacting so a hydrogen poor fuel. In case steam is introduced in the gasifocation process the produced gas is at least as good as woodgas, and much cleaner and safer to use.

Incredible result Tone! And difficult to see in the video how steep your hill is, but you can hear the engine work!
I love numbers! Keep them coming please

tone, nice chapel you have in your village…seems built from field stone? …
your tractor is really nice…have you an idea how much wood it consumes approximately in one hour?..only for make some theoretic thoughts in my brain…
my hanomag tractor has over 4 liters motor volume…

in germany this roof terracotta is called beaver tail… in short beaver.
this is the secret what the beaver has to do with the roof…

Giorgio, I have a hard time answering your question, because I work idle for a long time, I run a little busy for a while (carrying loads in the yard, moving trailers with light work in agriculture), well, I also pull a full trailer uphill, … I estimate that it consumes about 5 kg of wood per hour in this mode of operation.

I owe you some more information, according to the hour meter, the tractor spent 15 hours and consumed 9 liters of diesel fuel. Without wood gas, consumption would be somewhere between 50-60 liters, so in the mixed operating cycle, consumption was reduced by just over 80%. I also intend to renovate the diesel pump for precise dosing of a small amount of fuel and thus achieve those 90% wood gas and 10% diesel fuel.

Tone, 80% is still a good number. Many farmers would be happy to be able to cut down 20% on the fuel cost.
If you feel like using the camera in the future, a maintence vidoe on the system would be interesting. Condensation, ash cleanout, cooler flush etc.

JO , your number is definitely 99% wood gas, so I’m pretty far behind you, good to comfort me a little. 
I am also comforted when I think that the modern diesel engine 2.0 tdi at idle consumes approx. 0.8l / hour at 800 rpm, at 1600 rpm (these are the engine revolutions of the tractor, when the hour meter would be in line with the actual hour) the computer shows 1.3l / hour. If I think so, and the outdated 2.3l tractor engine is satisfied with 0.9 l of fuel per hour, I must be satisfied too. Cleaning will obviously be easy, only fine charcoal and ash are accumulating below, and the radiator and pipes are working clean for the time being.

Giorgio, I probably already asked you where you live in Italy, …? Which model is your Hanomag? You wrote that it is too heavy for the field (probably 3-4 tons) and that the engine has more than 4 liters. In Slovenia, the prices of IMT 533 tractors are quite affordable, it weighs around 1300 kg, if you are interested, …??

tone, thanks, i am in middle italy, is to far away for tractor transports, i also not need really the tractor, expect for heavy transport of stones sometimes…we make the most work with the draft horse on our mostly steep land…
for little transports, specially for dry firewood, i got a little kind of garden tractor -motoretta - from friendly neighbors, it has 10 hp, consumes very less diesel, and this we like to convert on chargas, yet not clear with spark ignition or diesel ignition like yours…
the hanomag r 460 is a oldtimer built 1964 with 4,5 tons…on much of our land i cannot go with it, because it is dangerous, with the horse i arrive nearly everywhere…but seen your successfull tractor, the desire comes up to modify also the hanomag, also when it is not needed often…

Giorgio, your Hanomag is interesting, it’s a shame he’s standing there

That tractor reminded me of this one. A Minneapolis Moline UDIX. It was supposed to be a hybrid. Farm tractor and daily driver. I think it didn’t do either well but I have seen recent auction prices around a quarter of a million dollars for one in pristine shape.
