CK20s HST fluids and filters

[Slackdaddy]

Engine oil and filter, no brainer.
The HST filter and fluid fill is kinda under and next to the seat,
but where is the HST drain plug ?

The Hydro filter is under the tractor, but where is the hydro drain and fill ?

The Owners Manual is not real clear.

The HST, aux. hydraulics, and the transmission are all the same reservoir. There isn't a seperate drain for the HST. The HST has a seperate curcuit in the tractor, protected by the HST filter and oil cooler, but is fed from the same reservoir. You fill all of the hydraulic fluid from the fill pipe next to the seat. The drain plugs are under the tractor, on the mid-pto case and transmission case. Look under the tractor, any drain plug is painted orange.

Don't forget about the front axle. Need to chage the fluid there also.

Slackdaddy, Thanks for asking the question, I am coming up on my 50 hr service and was wondering the same thing.
Michigan Iron, my 20cks hst does not have a mid PTO, are there still three drain plugs? I guess I will need to crawl under there one of these days, but not today, we are getting rain and sleet. Thanks for pointing out the plugs are painted orange. I am far from a dealer and therefore will be doing my own 50 hr.
