Hey I wouldn't feel too bad about the cost-I live in Olympia, Washington, and the nearest Kioti dealer is a 180 mile round trip. Last year my Kioti LK3054 was stolen from a jobsite, and thankfully it was recovered (more intact than not) and it cost $771.02 for a the full service (fluids/filters) a few minor parts, and of course, the labor. I ended up going through a nearby Kubota dealer to have this done because I wanted an experienced tractor mechanic to do the work, even though I normally do all my own tractor maintenance.
Anyway, getting to the point- its ALWAYS better to have a dealer/proessional to do the work (especially if you're inexperienced) on your machine for you even if it seems a little spendy. It's well worth it to have them service, or repair your tractor, because if something goes wrong on your end, it could end up costing a whole heck of a lot more. -Like I said, even though I've been doing all my basic maintenance, I still have my machine taken to a dealer every 3-4 years for service, just for that simple "peace of mind" feeling.
