>hydraulics self levelling has been a thing for 30 years and now its even better with integrated angle sensors.
Sounds expensive.
>and it saves having all that iron hanging out in front of the centre of gravity making the machine nose dive and reducing the lift capacity
Point to the massive amounts of iron hanging in front of the pivot point, images posted are just drafts, the final product would be relatively compact.
>reducing the lift capacity
It would increase the gross weight if just bolted on as an option.
>so keep playing vidja and maybe one day you get to run a real machine
Ran a kanga for spreading wood chip mulch, the self levelling was great for not having to think and lowing cycle time when dumping to the ground with the limited hydraulic capacity.

You sound like a Cat shill to kevech over a simple mechanical mechanism that could replace your electronics that satisfy the bean counters.
