The real positive point is that the pressure in the circuit remains at a low level when no function is activated. To my knowledge, no other model manufacturer offer this advantage.
I haven't made a test "in field" now, but the equipment forces seem to be way enough for serious digging.

Sorry for the long post, but I wanted to tell as much as I could about this model. I hope this helps

I like your review!
Please let us know how the castings stand to use and abuse.

In regards to dual stage hydraulic system;
- exactly what I have in mind for my project - if I ever get to that stage instead just pulling the trigger on the prebuilt model.

I think that the benefits of such system are in reduced energy wasted while the hydraulic system is "idling"... I'll have to try something similar with my hydraulic parts soon.

Oh, I nearly forgot to address the weight issue.
I know that it is very hard to pull a loaded trailer. 27kg, I bet the trailer has at least 3 to 5 more and that makes really heavy load. I don't fancy trying to tow that on a loose surface. But, isn't that what is fun? Building your tractor truck with large reduction rates, having decent amount of power, building and "cheating" the drivetrain to make it - yeah, that sounds fun to me!

Congratulations on your equipment she is a beauty and hope you have tons of fun with it and also thanks for all the info you have shared.

Thank you all for the kind comments!

For the weight on a trailer, I can confirm this is absolutely not an issue if you have a "beast" under the gooseneck......but do not consider tuning only the powertrain will do the trick : standard Tam suspensions will just be crushed
I strongly recommand installing a pair of Reg's excellent walking beams
