It's the same. With your tractor being a gear and not hst, you should only have one filter for the hydro fluid. There is an extra dedicated filter for the hst transmission models which still uses the same hydraulic fluid from the common sump. You would still use hydraulic fluid for the transmission which also lubricates the differential and brakes and this same fluid, from the common sump, also works your hydraulic pump for the 3pt lift and front end loader if you have one. That one filter keeps your hydraulic fluid "clean" for everything. Some members here do use UTF, universal transmission fluid, from Tractor Supply and say it works well. In my CK30hst, I have been using Shell brand hydraulic oil. As long as the oil meets specs, the brand is up to the user. If you drain, don't forget the drain plugs on each side of the rear axle. These should be shown in your manual and you'll need 7 gallons to fill.
