I want to add a oil cooler to our SCAG SWZ. I am pretty heavy at 220 for the thing to pull around and it has some hours on it causing it to slow noticeably after a hour or so when we are cutting large areas on hot days. Cheaper than new pumps and wheel motors would be an oil cooler. The thing works fine for a hour or so depending on ambient temp and terrain we are mowing. By the time we travel to the next job it works fine again also. So a question for the hydro techs. I am familiar with how to plumb the cooler but not with flow GPMs. Would a towing auto trans cooler such as those sold at the auto parts stores flow enough oil? I plan to mount it above the cooling air intake just like SCAG does on the riders.
