Sorry, there are few things as boring as having to explain your joke to someone, but the thruth is I don’t quite follow.
When it comes to mosquitos, we hardly had any so far. Too cold during spring and early summer this year. But I’m sure they are on there way right now.
Either way there will be no beer drinking this Midsummer weekend. I’m working tripple 12 hour nightshifts. We’re on our way to a family Midsummer lunch right now. That will be all when it comes to partying.

JO, I wanted to say that I have a privilege because I can do a lot of hard work very cheaply, my ancestors didn’t have that opportunity,… I can afford cold beer, wine, … when I drink, and the smell and smoke from the gasifier repels mosquitoes,… I have all the benefits to enjoy …
(The statesmen would definitely accuse me of evading the tax on motor fuels)
JO, it is often difficult to understand a joke, especially from a person who is happy that work is going well, that relations are good, but is not “educated” to say it in a humorous way …

I should have looked closer. At first glance I thought I was looking at a tracked vehicle front end with a small windshield at the top and headlight covers. I thought maybe you were going into the forrest business like Jan A. My bad.

Today while working, I remembered that in reality I could measure the power of Fergi on wood gas, I have a 50 m long slope with a uniform slope of 25% (on a length of 10 m it rises 2.5m). I drove this slope in 75 s, which means that I am rising at a speed of 0.1667m/s, the total weight of the tractor and the load is about 8000kg. If I use Goran’s suggestion and use the information that the power is 1kW if we lift 100 kg 1m high in 1s, then we can calculate the power of 13.33 kW or 18 hp. Let me say that the road is gravel and the wheels slip a bit, so I would actually cover this distance a bit faster (I would probably get 15 kW of power). I can’t estimate how much frictional losses are generated in the drive system and how much rolling resistance there is (maybe 5 kW), well, after thinking about it, I would estimate the power at about 20 kW or 27 hp (on diesel fuel it reaches 33 hp).
Mr. Don, let there be no secrets.

Tone, I don’t remember if you ever told us - what do you do with all the gravel you’re producing? Extension to your castle?

It would be interesting to know the ‘drawbar’ power of the original tractor on diesel. About the same as the the hill climb test power on woodgas?

Rindert, I promise that I will do the next ride on diesel fuel and measure the driving time on this slope, … I will report on that, I am also interested in what the result will be.

JO, I have a lot of macadam paths and areas to maintain where I need gravel, I give some to friends and neighbors, and I intend to build another stone building.
I have removed about 30 m3 of stones from this plot these days (10 tractor trips), I poured 15 m3 into the pit where the soil has caved in,… well, there is still at least 15 m3 of stones left to remove…

Keep up the good work Tone, love these reports 
Sure wish I had one of those crushers. Seen less than a handful for sale the last five years and I have not seen one cheaper than 4000€ / 4500$.
Definitely not in my budget but I still hope to stumble upon one some day.

I had to look macadam up Tone. Don’t think I have ever heard it to referred to as such. The definition I got says that it is used with a binder of some kind. Bitumen or tar. Do you use a binder on your paths? I could certainly use a lot of crushed stone on my drive way that was partially washed out with this week end’s deluge.

In Sweden macadam comes in different fractions but the main common thing is that particles smaller than 5/32” or 4mm are sifted away to be able to drain away water, no binder in it.
Will be interesting to hear what the meaning is in Slovenia.

A macadam road in Slovenia is no different from anywhere else in the world. Below is a layer of coarse gravel, and above is a layer of finer gravel. No binder is used, so roads on slopes are very exposed to washing out during rain, which means that such roads require frequent maintenance…

Macadam is a typical Belgium road for me, with hardstone 8 by 8 inch or so.
Is your Fergie still capable of digesting diesel? Nice test btw
Johan, found a crusher the last weeks for not to much money, but here are no stones to crush only mud. Should I tried to reach him?

Thank you Joep but unfortunately it will be too expensive getting it here even if it was pretty much free.
Plus it needs to be a size that can be driven with like a tractor I already have and still be big enough to be useful.

Interesting fact: macadam roads are named after Scottish road engineer Mc Adam.
Yes, it is true

So, today I tested driving up a hill on diesel fuel, I tried to overcome it in a higher gear, but there is no power, so I drove in the same (2nd gear) gear as on wood gas, it maintained about 2000 rpm, slightly higher than on wood gas, a slight black smoke was visible on the exhaust pipe, which is a sign that it was practically working at full power. The road is gravel and it is very dry and hot here, so there is considerable wheel slippage and the driving time was practically the same (75 seconds), well, I have to admit that it overcame the hill with diesel fuel a little easier, but there is no big difference.
Conclusion:
I estimate that the engine on diesel fuel is about 10-15% more powerful than when running on wood gas.

have you calculated also the reduced compression ratio in your experiment?
is it generally 10 - 15 % lower as diesel or in your modyfied engine?
though good performance, compliments…

Giorgio, I didn’t take into account the lower CR, but it doesn’t significantly reduce the power on diesel fuel, it’s just that starting a cold engine is more difficult, but when the engine is hot there is no difference in ignition, it starts at the touch of the ignition key. Modern diesel engines have a fairly low CR, Mazda only has 1:14,…
