Tractor has 532 hrs. I have not changed the hyd. oil. Does the steering work off the fluid in the trans. case or does it have a reservoir of its own? Also is it ok to use an after market filter. If so what is the part # of filter so the parts house can cross the number. The nearest dealer to me is about 75 miles. Thanks in advance for the help.
Yes, your steering works off the hydraulic fluid reservoir.
I have never been around a BX Kubota but I'm sure that it is like the rest of the Kubotas are. The Oil should have been changed at 50 hrs the first time to get the initial wear particles out of the system and then again at 300 hrs. Depending on the type of filter setup the tractor has and the fluid capacity it may just need the filters changed at the 300 hr mark but reguardless of which you have it definately needed service at 300 hrs. The trans/hyd system should be serviced every 300 hrs. from then on.
As far as filters go my preference is to stay with the Kubota hydraulic filters. You know for sure that they will have the proper specs that Kubota requires to ensure the correct filtration. I know how it is to be a good distance from your dealer. I'm not as far as you are but it's still about 35 or 40 miles for me. My dealer will have all the parts and filters shipped to me from the factory and just bill me for them. I haven't ordered any reciently but every time in the past Kubota paid the shipping cost. All I paid was the price of the filters just like I had went to the dealer myself. If I were you I would ask my dealer about this and see if they will do it for you.
I hope this will help you.
