This spring I traded in my CK20HST, that I bought last year, for a CK35HST. The 20 had 290 Hours on it, plowing, skidding and splitting, but the lift capacity was wanting and I felt the extra weight would benifit my terrain. So far the 35 is a jewel,(130 Hours) however I too have broked off the lower filter, in the bush. I needed to replace the filter housing and that took me a while since the dealer is 120 K away and I wasn't prepared to pay a lot for travelling mechanics. Did I mention I'an not, repeat, not a mechanic? I picked up the part, had a long chat with a real mechanic and spent the next 3 hours under the machine. Part cost $16, Filter $49, Hydraulic Fluid $112=$199.00. Was truly heartbreaking to watch all that hydraulic pour onto the ground. My dealer does the 50 hr free! My 50 Hr (after 2 weeks) cost me $97 for materials. It took a great deal of effort to remove those lower hydraulic filters on both tractors. I would recommend having the dealer do the first one even if you have to pay as I would have not gotten the filters off by myself and I had a good lesson as well. I am so very happy with my Kioti!
