Levelling machines have been around for ever,
the volvo excavator levelling package is an aftermarket product, built in either new zealand or auzzie, and one of their dealers originally secured the rights to sell it here in BC originally (we know 'cause we tried to get it approx 5 years ago). the system can be installed in any brand exacavator. It has nothing to do with Volvo
Volvo new forestry bunchers are for sure new. They probably are pretty good to be honest as it is a decent company.
Cat is WAY behind in the buncher market
Steep ground guys dont want auto levelling. Pushing the button on the joystick is just fine.
There are only 2 brands leading the way on big bunchers now, john deere and tigercat.
