Dear Jughead
Ist let me say ,I dont wish to be seen as a guru.
The loader you speak of .Is this a tracked loader[traxcavator]
Float. I personally seldom use float,as one needs to put down pressure on some places and feather at end of run..
If its a wheel loader then I have had little experiance of them.
My theory about [float] is that its a carryover from the old rope blades, where you can drop blade quickly,and I can remember yrs ago operators condeming the new fangled hydaulic blade.
Of course I could well be wrong and probably are.
As I understand it,Float is the [carry] position,as haveing loaded the blade,you float the load along,something I have had no success with.
The real Guru on Dozers is Ozdozer.
