Don't use hydraulic fluid, what you want is Trans/hydraulic fluid.
My Kioti Manual lists their approved brands for the LB1914. I don't suppose other non-HST models differ. I don't know about HST.
Some listed are:
Chevron - tractor Hydraulic Fluid (one gas sta carries it, but does not advertise - it's a word of mouth thing.)
Quaker State - Tractor Hydraulic
Union - Hydraulic/tractor fluid
I mention these because they all SOUND like hydraulic fluids, but in fact are transmission fluids which are also used in the hydraulics. I expect they are especially formulated for both purposes. No wonder the confusion!
I already have a supply for the next change, but at over $75 for 5 gal, I would like something a lot less pricey.
By the way, do you guys change the fluid at the recommended frequency? I changed mine at the required 50 hr and it looks clean and perfectly good after 200 hr. I don't know if it is invisibly degraded in some way. (I think the Chevron product I use is synthetic.)
I'm inclined to not take chances on brand and frequency because the fluid is so important for proper function, unless advised by a reliable source.
