B2320HST. I have a filter in the left side and in the right side by rear wheels. My manual calls for a transmission filter and a hydraulic filter. Which is which please?? The book is not clear. And what are these filter numbers? Thanks

The HST filter is a finer media filter than the hydraulic filter.

Hydraulic Filter Right side
HH670-37710

HST Filter Left side
HHK70-14070
