Paul,

I am very intrigued in the hydrostatic system you describe for a 406/416 and am curious if that is the way they came from the factory. Do you know if it is? In the statement you made above

First, there is a variable displacement hydrostatic piston pump that looks like it's driven by the rear PTO output - engage the pto and you drive the pump. Next, there's a hydraulic piston MOTOR attached to the bottom PTO where the optional backhoe PUMP is normally installed. So it appears that they're using one PTO out put to drive a pump which powers a motor as input to another PTO to drive the transmission instead of the engine. This way you could have infinitely variable vehicle (low) speed at constant engine speed. Any thoughts? Am I out in the weeds on this?

how does the bottom PTO power the drive train (wheels)? Isn't it separate from the transmission for the wheels just like the side mount PTO unit is?

TIA,
Blane

Does anybody on this list have an hydrostatic drive setup on their 406 or 416 truck?
