Been using the tractor quite a bit in the last couple of weeks and 50 hours snuck up on me. I happened to be driving by the dealer today so I picked up the three oil filters (Really? $40+ and $60+ for hydraulic filters?). I found hydraulic fluid at WalMart that is compatible with Kubota's UDT and some Shell 15w-40 for the crankcase. Hopefully I have time to get it changed tomorrow.
