I have a BX2350 with only 350hrs on it. I have already replaced the seal on the "knuckle" that attaches the axle to the left fron tire. I now need to replace the seal on the right tire. I have also had other hydrolic leaks. I don't pressure wash my tractor or abuse it. Is this a common probelm for Kubota's? It seems that these major seals should last much longer than 350hrs of use.
