Hello buzzy, thanks, the machine is around 450lbs (205kg) now, will be another 25- 30lbs when "filled up" with fluids. Yes, the hydaulic system have more than 2 gallon of oil!
The ripper tooth is 4,5lbs (2kg), the big scale adds up a lot of weight.
When starting this build I made some calculations, in my thoughts then was a model weight of 140kg. The "scale" weight was calculated to 216kg so it turns out that I'm hitting the weight almost spot on!
