Getting ready to do 50 hour service on my ck4010se with hst. Still debating about to change the hydraulic oil or not. Already bought 5 gallons of Mobil delvac. Manual says 5.3 gallons. Cant seem to find any more local and cheapest I can find online is Summit 2.5 gallons for about 52 shipped. Wanting to know how much oil actually drains out with the change? Seems like there would be more than .3 gallons in the pump and the lines. Thanks

Welcome from Missouri.
Most folks do not change hydro oil at 50 hours. Only change the filters.

This is what my dealer uses and recommends.
Appreciate the replys but what I am asking from someone that has changed the oil is how Much did it take to refill. Yes I know it does not call for the Hyd oil to be changed til 400 hours..also Mobile Delvac is Mobile 424 which is the Kioti recommended oil per the manual.
Thanks
Thanks

Your owners manual should list the capacity of all fluids.
Attached is a list I found but think it is older and may not include recent models.

Save the oil, change the filters. Hydraulic oil during the first 50 hours, 100, 200, 300, 400, hours has a little material captured by the filters. It has not degraded. I know it feels good to put new stuff in but the tractor could careless. I suspect if it takes 5.3 gallons you might squeeze in 5 gallons. I pulled the plugs after use and let it drain overnight. The oil is subjected to brand new parts that only contribute a little metal, normal break in. The filter easily catches it.

What he's asking is if 5 gallons is enough to do an oil change. He doesn't want to purchase another 2.5 if it's not necessary. I changed mine some time ago and don't have an answer for you but I also used it in my front differential so I needed to purchase 3 of the 2.5 containers from Summit.

I was not clear. I suspect he might make 5 gallons work especially if that includes what is in the attachments since that is not draining out. As you mention, the front differential can also use the same fluid. I suspect there are those here that only want 80-90W because it "seems" better. I suspect because of the very slow speed, most lubricants will suffice. I get hydraulic oil that comes in 5 gallon or 1 gallon containers. If the one gallons cost the same as a five, I would prefer the ones simply because they are easier to manipulate. The 5 is handy to put the used product in easier.
