I own a Kubota L2650 DT, recently I contacted Kubota about parts # 35080-40350, 35080-40380, 35060-40400, and 35060-40450. These are hydraulic lines that control the steering. I was informed Kubota no longer produce these parts and no other products were given to replace these parts. I am now waiting to here from Kubota if any technical diagrams can be given with detailed measurements so these parts can be manufactured.
