I have had the idea to convert an old 3 wheel golf cart to hydraulic drive. what are my major decisions in taking on such a project? I have a pump, motor and engine. the cart has a gearbox and i belive adapting the hyd motor is no problem. my concern is acceleration, braking and ratios needed for speed. has anyone ever done this?

The most common use us a close loop hydrostatic transmission.
Have a look at the attached typical curcuit.
Sizing and selecting the right components is another story.
More date required such as rolling resistance, slope, speeds
and power available. Such a system will control acceleration,
deaceleration even constant power and torque control.

Your best bet based on your present knowledge of hydraulics is to go to a local Tech school and talk to the Hdraulics Instructor to see if he might take this on as a class project. I know a similar undertaking was handled by a local Tech Colege class some years back and the instructor was happy to have a real world circuit to design. In fact it was one of his students and they also plumbed the circut they designed.

Trying to design a circuit and get you up to speed so you could understand it is beyond any forum such as this.

Take a look at this web site to see a similar undertaking for a Motorcycle Hydro-static drive. That will give you an idea of what is involved and why you need a lot of knowledge about hydraulics.

Here is another web site on a Military vehicle that is hydraulic drive.
