    I agree, I had paint, metal cuttings [spirials] from machining, sealant, and dirty oil. If one of my customers had that dirty of oil in their hyd system I would have been all over them. The 50 hour service is the most important one IMHO. I changed my engine oil at 10 hours just to get the break in crud out of it. Oil does not wear out it just get dirty and looses the additive package. So whatever comes first the oil needs to be changed, filtered or the additives put back in. With the small amount of oil these tractors hold it is more cost effective to change it. I have a few customers that run large cranes and equipment and we use offline filtration to 3 micron and do oil samples to see what needs to be added. A couple of units have had the same oil for 15+ years. CJ

    Just my 2 cents worth here, your pump was making nasty noises due to being starved of oil which is very hard on them. Personally I would find the correct Amsoil product to run in your tractor from one end to the other. Yes it is expensive oil, but I feel it is also the best lubricant you can get. I use Amsoil in everything I have bought new. From my last Peterbilt down to our ATV's. I can't say enough about the products. I sold my last Pete with 1.2 million miles on every component in it and nothing had ever needed replacing. I'm currently looking at getting a new DK45 HST with cab myself, and with the cold winters of Saskatchewan it would be getting full synthetic oils from one end to the other because I don't have a heated shop for it to be in and it needs to be able to go in extreme cold. Hope this helps someone.

    Welcome to the forums. 1.2 million miles (km?) is pretty impressive to be all original. I love my DK45 cab, it handled it's first Ottawa winter with ease and I only plugged it in once or twice. I put it in the biggest Shelterlogic that Canadian Tires sells to keep it out of the wind and snow in the winter and sun in the summer. They go 40% off fairly often and I'd recommend it over leaving it out in that Saskatchewan wind.

    Thanks for the welcome kiotiken Yes 1.2 million miles, or just over 2 million km on the odometer when I sold her. I do have a shed that I park the tractor I'm using in the winter in to shelter them, makes a big difference. I use Amsoil in my Ram diesel, wife's new car, welder, JD zero turn mower....everything. For extended oil drains on engines though you have to run extra filtration IMO, that's what I do. I'm looking at a Kioti because parts are getting hard to find for the older tractors I have and the run well so it is getting time for a new one to preserve the old ones, and I want a cab and heater for the winter cleaning snow. I drove one of the DK45se HST tractors around at the dealers lot a couple weeks ago and moved a bit of snow there. It seemed to be a good little tractor, especially for the price.

    My first tractor, a Ford 8N, changed it's own transmission oil...about every 40 hours...whether I wanted it to or not!

    Current tractor makes me do it...

    It is my intention at the 100 hour mark to go with full synthetic engine oil. I will talk to the dealer about synthetic for the hydraulics and see what he recommends. By the fall I should have synthetic in both the front and rear diffs as well. i will be putting synthetic in my heep as well. It only has 246,000 kms on it.

    As CJCONE stated earlier, you want transmission fluid that is specked for wet brakes and clutch packs on the container. If it were me I'd try to stick close to those types/brands that are closely related to what is outlined in the owners manual.
    I have NOT changed my HST trans fluid in over 515hours to date since new and have NO problems whatsoever.
    I was going to change at 400hours but didn't get round to it. I will probably change it soon just to have done it and to see what the fluid looks like when I drain it and inspect it for stray varmits and lost tools etc.
    I did my 400 hr interval service yesterday and did not change the hydraulic fluid. My dealer told me it is a waste to change the hydraulic fluid for my conditions where the system is not worked hard. I don't have a backhoe or do sustained hard pulling. He said an 800 hour interval would be fine and a Kioti technical rep agreed changing more often is a waste. He said if I was using the tractor for continuous heavy pulling the 400 hours might be reasonable. The last time we discussed it he suggested 600 hours may be more appropriate. So I'll ask again when I'm near the next 200 hour service interval. But I imagine I'll let it go to 800 hours.

    Although not changing the hydraulic oil, I do change the HST and hydraulic filters at the specified (200 hr) intervals.

    I also changed the hydraulic oil at the first 50 hour service and believe that is a good idea.

    I did my 400 hour service at 450 hours (actually 460--10 hrs late, and 200 hr service was 253 hrs, 3 hrs late). I consider the 100, 200, 400 service intervals to occur at 150, 250, 350, 450, 550.... since the first service is at 50 hours. I realise some don't agree with this.

    Your machine, your service program. If it works for you, then just do it.
