There should be a strainer under the right floorboard. It's similar to an element-type oil filter in appearance.
The transmission filter is on the left side of the machine under your arm. Good luck with that, if I remember right it can be a fun one to get in and sealed. The hydraulic filter is in the oil tank on the right. Or at least it is on the G series, is yours a G or E?
Losing an oil cooler or a supply line can burn them up in a hurry.
