Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. Quick, easy and effective.

I also asked him if this would work on the hydraulic system of your Scag lawn mower, and he said that the # D13212 would work as it is pressure tested to 350 psi.
I attached a link to a transmission cooler FAQ page below that you might find informative also.
