You touch on one of the reasons I won’t have ISO. As far as I know, all current ISO machines are fly by wire, and that gives a miserable response compared to the older mechanical control systems. Even H pattern electric over hydraulic is miserable.
Quite a few of the ISO machines are pilot controls. The ASV loaders I was looking at have that control system.
If I understand correctly, pilot controls just take those small pilot valves out of the hydrostat pumps, and move them into the control levers instead. There's some long small-diameter hoses that connect the pilot valve to the servo pistons in the pump. It functions exactly the same as the older machines that connected the control levers to the pilot valves with mechanical linkage, just without the sloppy joints.
That's just my limited understanding without having had a chance to dive under the hood of one of those pilot-control loaders. Someone else can correct me if I'm wrong. |
yet another h-pattern vs iso post....
