The frozen ground melted a week ago and the soil was pretty dry, so I decided to start harrowing the cropland today while I have time. I borrowed my neighbor Ruben’s harrow, which is broader than our one. This is going to be really exciting, because it will be a good test to see how strong the tractor is on wood gas and how it will perform in the cropland. I prepared a fuel log to keep track of the fuel consumption.

I started with fir wood in the tank and the tractor performed ok but not really impressing. I then fueled with birch and felt an increase in power as soon as it began to combust in the gasifier. I was now able to use high gears on the dry parts of the land while the more clayey land near the lake was rougher and needed low gears.

When done I calculated the fuel consumption to 60 liters of wood per hour.
