Oil & Fuel 50 hr service, didn't change hydraulic oil

[dfkrug]

The 50 Hr Service is probably the MOST important service one can perform on a tractor.

The magnet on my plug looked like a Chia pet.

I agree this first major service is the most important. I think all new
tractors will have many metal fragments from machining in them (I sure
did).

The other big reason to change the hyd fluid at 50h is that no one seems
to know what Kioti used. It is most likely some generic hyd oil, not a
brand name tractor-hyd fluid that is designed for HSTs and wet brakes.

I don't think my dealer did mine at 50 either.....hmmmm I think I'll jump on that.

my DK 35 was not done till 100 hrs,,Dealer said it was ok till then,I did all fluids and filters then and all is fine.

Were I work we have a Kubota 4630 hst and that dealer said same thing,,(we dont service them till 100 hrs.
So it sounds like it might be some what common?
I would think dealers would want to do it to make money?
who knows?
just my 2 cents!

The way I read the post, the dealer changed the oil but not the HST oil. Which seems fine to me and I think that normal. Changing the engine oil at 50 is a must for the most part to get all the metal shaving out. I thought the engine oil and HST oil is two different things, or am I missing something in this thread. ?

Trust the manufacturer and change the engine oil at 50h with a
Diesel-rated engine oil, AND the Hydraulic oil (7-9 gallons, depending
on implements) with a branded Tractor-Hydraulic fluid. The latter
oil serves the HST, the hydraulic system, the wet brakes, and the final
drive (rear end). It is all in the owner's manual.

I see little shavings in the engine oil, but many metal pieces in the hyd
oil. Change oil and filters!

I know if I had a tractor with a crash box transmission and dry brakes more than likely I wouldn't change the hydraulic fluid. But, If I had a tractor that was hydro, PowerShuttle, powershift or had fluid brakes, there is no way, no how that the fluid and filter wouldn't be changed. Given the size of passages, fluid clutches, the close tolerance passages and the fluid covered wears surfaces in these systems, the fluid needs to always be keep clean as possible and that means removing any containment from the manufacturing process.
