Agreed some of the parts are pretty pricy. There are all sorts of reasons why some parts might be pricy. Maybe the supplier ran out and they need to make the parts one off? Maybe the machine is old and you're dealing with a limited number of stock items? Maybe it costs more to make than you think?
Overall I feel that Kubota doesn't gouge you for things like filters, fluids and normal service items like seals and bearings. The prices are honestly pretty good, and often i can get an official Kubota filter cheaper than an aftermarket like Napa or elsewhere.
However as with every mfg, we find some parts which are just priced absurdly. Our choice is to suck it up and pay, or leave our tractor broken...there are VERY few aftermarket options for most parts and some are Kubota specific.
